This comet was difficult to be observed, from its faintness, and from the indistinctness of its nucleus: it is also somewhat uncertain whether the orbit was truly hyperbolic, as it appeared to be, from the observations of the first months in which it was visible.

Hitherto I am not acquainted with any other observations of this comet than those of Gambart, Schumacher, Nicolai, Harding, and Olbers, most of which are printed in the Astr. Nachr. IV. N. 81. The elements have some resemblance to those of the second comet of 1790, N. 93; but they differ from them too much to allow us to suppose the comets identical.

Home, Bart., F.R.S., was read. This paper contains the account of a repetition of the author's former experiments upon the effects of dividing the nerves supplying the velvet of the deer's horn, in which the same results have been obtained, while some exceptionable parts of the former proceedings have been carefully avoided. It was now found, as before, that immediately upon the division of the nerves of one horn, the temperature of that horn was diminished sometimes to the amount of 7°, and that in the course of ten or twelve days the disparity of temperature between the two horns began to cease, and they ultimately again attained precisely the same temperature. When this was the case, the deer was killed, and the parts carefully dissected and examined, when it was found that the interval occasioned by the recession of the divided nerves, was filled up by a newly-formed substance, which firmly connected them, and this explained the restoration in their functions which had taken place. In further proof of the influence of the nerves over the evolution of heat, independent of mere sanguineou scirculation, Sir Everard adverts to a case of aneurism, in which he tied the femoral artery immediately below Poupart's ligament. The obstruction of this large arterial trunk, however, did not occasion diminution of temperature in the foot, below the natural standard. any 306 Proceedings of the Royal Society. your country, and secured the gratitude of a body of men who are not tardy in acknowledging benefits."

As in commerce, so in science, no one country can become worthily pre-eminent, except in profiting by the wants, resources, and wealth, of its neighbours. Every new discovery may be considered as a new species of manufacture, awaking novel interest and sagacity, and employing new capital of mind. When Newton," said the president, "developed the system of the universe, and established his own glory and that of his country on imperishable foundations, he might be regarded as giving a boon to the civilized world, for which no adequate compensation could ever be made; yet even in this, the most difficult and sublime field of discovery, Britain has been repaid, if not fully, yet fairly, by the labours of Euler, La Grange, and, above all, La Place, perfecting the theory of the lunar motions and planetary perturbations, and affording data of infinite importance in the theory and practice of navigation. Fortunately, science, like the nature to which it belongs, is neither limited by time or space; it belongs to the world, and is of no country and of no age-the more we know, the more we feel our ignorance-the more we feel how much remains unknown, &c. ;-and in philosophy, the sentiment of the Macedonian hero can never apply there are always new worlds to conquer." On delivering the medal to Mr. Barlow, the president said, that although he had already been honoured by marks of approbation more valuable in a pecuniary point of view, he trusted that none would give him more durable satisfaction; " for this award," said Sir Humphry, "has, I believe, never been made, except after dispassionate and candid discussion; never to gratify private feelings, or to call for popular applause. We trust," continued the president," both on account of the public good and your own glory, that you will engage in and accomplish many new labours You have not merely had scientific success, but one still more gratifying to your feelings-the idea that you have been useful to |
