My Mr. Sutton says that the alkaline developer would which the print is formed to the opacity and whiteness necessary to give it any value as a picture. experience does not agree with this. Alkaline pyro entirely unrestrained by soluble bromide in the collodion or in the liquid, brings out but a faint trace of an image before it can be seen to discolour the film all over, very little more when light has acted than when it has not. Strangely Fancy Mons. Marion's new process amounting to the same thing as Mr. Swan's original process, in which he printed through a collodion film, with the back of the sensitive pigment towards the negative! And fancy Mr. Taylor's suggestion of printing through a sheet of paper being valu-enough, under these conditions, the film only changes able for purposes in which extreme delicacy is required! And fancy Mr. Swan's suggestion of printing through oiled paper! Why, that process as actually employed by Mr. Blair before Mr. Swan was ever heard of in connection with carbon printing. years Since writing the above, I have been spending a few days with Mr. Pouncy, and have witnessed all his manipulation of his new processes. I advise my readers to have nothing more to say to any of the existing modes of carbon-printing. Mr. Pouncy has discovered a method which supersedes them all, and in which no transferring of the print is required. Anyone can work the process; it is the simplest thing imaginable. More of this shortly. I speak now of the gelatine and bichromate process. All troublesome transferring is avoided; but as I said before, I still prefer greatly the method in oil-paint. NOTES. BY MAJOR RUSSELL. THE BROMIDE PROCESS. ONE of the best workers with the bromide process tells me that he gets ample opacity of film by exciting in a 60-gr. bath for five minutes, and that he cannot keep the plates in longer without producing fog, after twenty-four hours' washing, unless by giving a long exposure, and using a great deal of bromide in the developer. The very old bath which I have been using must contain a large quantity of other nitrates besides that of silver, and therefore does not hold so much nitrate of silver as is indicated by the argentometer; but this is not sufficient to account for the difference of experience. The plan recently described always answers well in my hands, but whatever the conditions which may cause fogging, when my directions are followed exactly, this state of things, so far from being a difficulty, is an advantage when the process is understood, for it shows that less time in the bath is required. colour very slowly to a brown, and will not intensify to an opaque black, at any rate, with the same strength of developer which, if properly restrained, would have intensified the exposed parts well. An alkaline developer not quite restrained enough fogs slightly from the first, but the fog is not easily perceptible for some time; and fog is often produced towards the end of the development by strengthening the developer too much for the restraining bromide present. A well restrained alkaline developer acts vigorously on the exposed parts, but may be left on for it will, however, in time, stain them of a transparent twenty-four hours without fogging the unexposed parts; brownish yellow colour, the darkened liquid acting as a dye, which can be washed out. Mr. Sutton's mode of accounting for solarisation hardly agrees with the fact already mentioned, that bromide of silver when blackened through by exposure and alkaline development can be entirely dissolved away by dilute nitric acid so as to leave the film transparent, while unexposed bromide of silver remains undissolved around the exposed part. How is it again that similar solarisation occurs on daguerreotype plates on which the sensitive layer is iodide and bromide of silver without any organic matter? I quite agree with Mr. Sutton as to the importance of understanding our processes, and like him only want to find out the truth. I propose before long to make an experiment which will go far to determine whether or not an organic silver combination formed by the bath is necessary with the bromide of silver. Some curious facts have been recently observed which, when more fully investigated, promise to throw some light on the manner in which tannin, and perhaps other organic matters, act on dry plates. A curious, and if correct, important paper on the electrolysis of water has been published by M. Bourgouin. Pure water, he states, is never decomposed by electrolysis, whatever the strength of the battery employed, or however If, equal weights of pyro and carbonate of ammonia long the attempt may be persevered in. Sulphuric acid or an being used in the developer, bromide of potassium in the alkali is always added to enable, it is said, the water to conduct proportion of one-fourth the weight of either will not pre- electricity. M. Bourgouin's experiments, however, go to show vent fog, use a bath as weak as will work well, and, if that these bodies perform a more important part than mere connecessary, keep the plates less time in it until they will ducting agents. When potash was employed, he observed that develop clear. Washing for a much shorter time is another the amount of hydrogen disengaged was always proportional way in which fog can often be prevented, but it seems to to the amount of potassium carried to the negative pole, and be more advantageous, on the whole, to leave a fair amount his opinion is that it is a hydrate of potassium K HO, which of bromide unconverted by the bath at the back of the is decomposed Similarly, in the case of water acidulated with film, and to remove it by long washing. Besides, the sulphuric acid, he believes that a hydrate S H3 O is the body plan of making two operations of the exciting and finish-in the action than to continually replace that removed from the electrolysed, and that the excess of water takes no further part ing, with twenty-four hours between, is as convenient as compound named. The author's views we do not expect to be any other way; it is easy to keep the plates perfectly left unchallenged, and we shall probably hear a good deal on protected from light in a vessel. the subject.-Mechanics' Magazine. MR. SUTTON'S NEW THEORY. In Mr. Sutton's article (p. 295) nothing appears which will reconcile his theory with the facts mentioned at page 271. The effect of dilute nitric acid on a fully exposed and developed portion of a bromide film, proves beyond all doubt that bromide of silver is reduced by alkaline pyro. That no organic combination formed by nitrate of silver THE ILLUSTRATED PHOTOGRAPHER is making friends in all parts of the world, and right earnest, true, active friends some have proved. In the Toronto Globe for July 3rd, an advertisement appeared offering to forward any photographer who would send the advertiser-Mr. Wyles-a penny postage stamp, one copy of our journal. We felt quite a thrill of grateful pleasure in receiving this practical evidence that our labours are appreciated from a generous stranger in a land so far away N the present number I give five specimens of posing. The initial block is from a photograph by myself, and the sketch above it is from a photograph by Mr. Cox Walker. Fig. 1 is from a carte by Mr. Wyles, of Bourne; fig. 2 by Mr. Oliver Sarony; and fig. 3 is also by Mr. Walker. Numerous inquiries have from time to time been made respecting the publication of these illustrations of posing and grouping in a separate form. I am happy to be able to state, that at the end of the year they will all be re Fig 3. printed and published separately, so as to be convenient for reference in the studio. I have received some very suggestive pencil sketches from nature, by G. A. and L. B., which the donors think might prove suggestive and useful. Some of these I shall have much pleasure in using. I am promised for next week an illustration by a new photographic process of producing relief blocks, which, judging by some specimens kindly shown me by Mr. Fruwirth, of Sydenham, is likely to be very successful. The drawing for this specimen has been made by Mr. Wall, and will be reproduced by the photographic and electrotype processes, by the inventor, Mr. Courtenay. On another page the reader will find a few remarks devoted to this subject, which is, I believe, one of very great importance, and opens out a field of greater commercial importance than any into which photography has yet entered. On the occasion of my visit to Mr. Fruwirth, I also saw some of the finest specimens of photo-lithography I have yet met with. Photographic Wanderings. A TOUR ROUND THE COAST OF ANTRIM. BY R. H. KINNEAR. If the editor will be so good as to publish these few jottings, which I will endeavour to make as interesting as possible, I will give a slight sketch of my annual photographic ramble in search of the picturesque; and as this is a cheap route, I hope many looking out for a week or a fortnight's jolly, cheap, and withal profitable photographing, may be induced to go round the coast of Antrim; for in no place that I have ever heard of or seen is there more beautiful scenery. Nor is there any sameness in it; for one time the tourist, on an outside jaunting-car, will be rolling smoothly through a fertile and well-cultivated valley, and at another creeping over mountains which from the valley looked unpassable: then along the coastroad, with a beetling cliff at one side rising five to seven hundred feet in a direct line, and on the other the "blue sea" dashing to within a few feet of where he sits, as he spins" along. If the engineer of that coast-road had worked with a poet and painter at his back, he could not have laid out its course more agreeably for the eye or imagination. It is constructed with equal skill, taste, and enterprise-cliffs cut through, chasms crossed, water-courses walled and bridged—a roughly ribbed and rugged coast, in short, traversed by a road as smooth and level as a tenniscourt. It runs from Larne to Cushendall. But I am anticipating, and must start on my tour before describing the places of interest. 66 About this time last year, my friend and I started on a flying tour through this beautiful country, wishing to transfer to our albums a few of the best known and finest "bits" on the coast. Our, or more accurately speaking, my, process was the wet, my friend being a non-photographer--to his loss be it said; but he was a very pleasant companion, as well as a very useful auxiliary in carrying tent or camera-box, as the case might be, for the principal part of the journey was made on foot. From Belfast we started by the Northern Counties Railway for Larne, and while my friend got the tickets, I saw all the necessary traps (dark tent, camera-box, two tripod legs, and a box of spare chemicals) safely stowed away in the luggage-van, took our seats, heard the usual bell, whistle, and exclamation of "We're off," and away we sped, along the shores of the Belfast Lough, which I have heard compares for scenery favourably with the Bay of Naples. Past the neat villages of Green Castle, Whitehouse, and White Abbey, each village with its flax-spinning mill and bleach 70 The general principle is that the light passes only through a small aperture to a sheet of prepared paper moved slowly by clockwork. The orifice rises and falls with the temperature. The same principle can be applied in various ways to record the pressure of steam, &c.-Engineer. green, the white linen belonging to which, stretched away up the slopes of the hills, giving with the green a most picturesque effect; and on the other side of the Lough are the Castlereagh hills, Sydenham, and Hollywood, suburbs of Belfast; Bangor, a favourite bathing-place in summer, and Groomsport, where Schomberg first cast anchor in Ireland, in the reign of William the Third, till, coming out of a cutting, we find ourselves within view of the town and castle of Carrickfergus, where Paul Jones appeared in 1778, and, after a bloody engagement, captured the British sloop of war Drake. The castle lies at the end of a small bay, and forms a noble protection to the Belfast Lough, from every part of which it has a most picturesque appearance. The At common tides three sides of the castle used to be enclosed by water; but lately, on one side, there has been a pier and breakwater built, where a number of fishing-craft and a few "colliers" are generally to be seen. greatest height of the rock is at its further extremity, where it is about thirty feet, shelving considerably towards the land; the walls of the castle following exactly its different windings. Towards the town are two towers, called, from their shape, half-moons, and between these is the only entrance, which is defended by a straight passage with embrasures for firearms. About the centre of this bridge was formerly a drawbridge, a part of the barbicons which protected the bridge can still be seen. Between the half-moons is a strong gate, above which is a machicolation or aperture for letting fall stones, melted lead, or the like, on the assailants. Inside the gate is a portcullis, and an aperture for the like purpose as that just mentioned. In the gun-room of these towers are a few pieces of light ordnance. Within the gates is the tower-yard, or balium; on the right are the guard-room and a barrack; the latter was built in 1802. Opposite these are large vaults, said to be bomb-proof, over which are a few neat apartments occupied by officers of the garrison, ordnance storekeeper, and master gunner. A little south are the armourers' forge, and a furnace for heating shot, near which, on the outer wall of the castle, is a small projecting tower called the "Lion's Den." This tower is divided into five stories; the largest room was formerly on the third story, with semicircular windows. It was called Fergus's dining-room, and was twenty-five feet ten inches high, forty feet long, and thirty-eight broad. Within the keep was formerly a draw-well thirty-seven feet deep, the water of which was eminently celebrated for medicinal purposes. It is now nearly filled up with rubbish. As to the age of this castle I have nothing by me at present which would aid me; but the following notice is given in a survey by George Clarkson in 1567: "The building of the said castle on the south part in three towers, viz., the gate-house tower in the middle thereof, which is the entry at a drawbridge, over a dry moat; and in said tower is a prison and porter'slodge, and over the same a fair lodging, called constables' lodging; and in the curtain between the gate-house and west town in the corner, being of divers squares called cradyfugus, is a fair and comely building, a chapel, and divers houses of office, on the ground, and above the great chamber and the lords' lodging, all which is now in great disuse, as well as the couverture, being lead, also in timber and glass, and without help and reparation it will soon come to utter ruin." However, the prophecies of Mr. Clarkson have not come true as yet, for it is still in very good repair, having had a helping hand now and then from Government perhaps, and is still a rather formidable stronghold. What it must have been when it was built can only be left to the imaginative reader. However, as the railway goes through a cutting just at the town, we do not get a fair view of the castle, and this description is only from previous experience, and while I have been describing the castle, the train has been moving on through the tunnel at Whitehead, past the large limestone quarries, and through what is believed to have been the bed of the sea at one time, between Island Magee and the mainland, through the little village of Ballycarry, and along the rather flat and dreary shores of Larne Lough to the town, a very good view of which is got from the railway, getting the ruin of Olderfleet Castle in the background. This was the end of the journey by train, and, while waiting for the post-car, I gleaned the following from the obliging landlord of one of the principal inns : Larne was anciently called Inver (which means lowly situated). Its trade was once of importance, but gradually went to Belfast. It is now brightening up again. A year or so ago a trial was made to run a line of steamers between it and Stranraer; but from some unforeseen cause (perhaps want of money, or more probably want of traffic), it was stopped, and Larne will likely now remain only as a dependent on the larger seaport of Belfast, except for coals, &c., for the town and country round, and exporting rock-salt and limestone, both of which used to be exported in large quantities, and, I suppose, are so still. There is also a good deal of cotton-weaving in the poorer parts of the town. The most interesting historical record in the vicinity of Larne, is the Castle of Olderfleet before mentioned, standing on the end of the peninsula, the Currain,* a sort of natural pier, forming the northern side of the Larne harbour, and completely commanding the strait by which it is entered. In the road from the town to the castle the ruins of a little chapel, called "Clondumales," are passed. The castle is now an insignificant ruin; but the advantage and dignity of its situation can never fail of attracting the visitor. It is supposed to have been erected by one of the Bissetts, a powerful Scotch family, upon whom Henry III. bestowed large possessions in the Barony of Glenarm, some of which were forfeited by Hugh Bissett in the reign of Edward II. for rebellion. James M'Donnell, Lord of Cantyre, asserted his claim to this land in the right of the Bissetts, but his son Æneas was content to accept of them on conditions approved of by Elizabeth, viz., that he would not carry arms under any but the kings of England, and would pay an annual tribute of hawks and cattle. It was on the peninsula of the Currain that Edward Bruce effected his landing in 1315, with the expectation of making himself king of Ireland; which vain and foolish ambition caused so much bloodshed through the east of Ireland, and was productive of such dreadful calamities to the English settlers particularly. (To be continued.) Currain is a corruption for carrain, a hoop, which the curved form of the peninsula suggested originally. THE LONDON PHOTOGRAPHERS' HALFHOLIDAY.

SIR, I beg to have a word with you, through the organ incorporated with your late publication, the Notes. Your estimate of a certain claim in reference to the carbon process is just about the "real grit ;" and when any, or all, of the present processmongers can put on one side and do without the genuine discovery of Mons. Ponton, then, and not till then, will they have claims fairly based on justice, law, and truth. With respect to their patents, I firmly believe that the greater part of the same are not worth the material on which their language-twisted nonsense is written or engrossed. The Southampton photozincographic process has been rather a poser to many patent claimants who have threatened a "little law;" but on second thoughts, and finding they would have the "Crown" for a defendant, have taken a little wisdom" and dropped the threat." All photo patents are more or less delusions, as the progress of invention is so swift and sure, that the wonder of one day is eclipsed by the wonder of the next. A reliable simple carbon process, quite independent of "Swan's patent," is only a question of time. Ponton's discovery, which is free to all, will most probably be as it has been and is, the base of every process, while simplifying the other details will follow in the course of experiments. The process needed for general use is one similar to the relief process. Now, the foundation of this is if the various patents will "hold water." I am quite ready the old story, Mons. Ponton. Again, it is remarkably doubtful and quite willing to give all the patentees every praise and credit for their industry and perseverance in carrying out a series of experiments based generally on the discoveries of others-Ponton in regard to bichromate, to wit; for it is exceedingly probable, and quite possible, that if the unselfish Scotch surgeon had not freely communicated his discovery to the world, a great variety of patentees and process-claimers service has Fox Talbot been to art. He was not a needy man, would never have been heard of. Again, let me ask you, of what and could very well have given his discoveries, as a contribution, to the world of science; but in lieu, he preferred to surround mangerism, consequently the whole of his proceedings have been himself with a lot of costly patents, a sort of dog-in-theof little value to himself, and less to the world at large; so I again repeat that the method most needed is a block-printing or mould method for printing, with or without letterpress. The great rock on which many have split has been the aiming at high art, attempts to produce something beautifully perfect and clear, which, had the operators commenced at the bottom of the ladder instead of the top, would have been successfully accomplished cards, and a host of commercial wants that would have met with a ready sale, and where a speck or a trifling blur would have been of no moment. This would have led to improvement, through practice, and many fresh advantages would have been secured during the course of the same. Had this plan been followed with regard to Paul Pretsch's photo-galvanographic process, it would by this time have been a great commercial success, instead of being, as the sporting papers would say, "nowhere; "therefore if Mr. Sutton will turn his attention to service, and further merit the good wishes and thanks of the a photo-cast printing process, he will do a large amount of votaries of an art that he has, individually, considerably benefited and advanced. If Mr. Blair were to publish his simplified carbon process in a pamphlet at a shilling, and sell the material to the public for carrying out and practising the same, he would get paid for his outlay, without sinking money in patents and protections, which have, as a rule, with but few exceptions, been signal and decided failures. I have little faith in companies, but much in single-handed energy and enterprise.

Lockyer, High-street, Ringwood. Loan Exchanges. UNDER the above heading, a subscriber who may have something which he would be willing to lend, for something which he is anxious to borrow, may make his desire known.
