tion. The venom of a poisonous animal, the matter of smallpox, and many other contagions, produce their influence through the medium of the skin. Infectious diseases are communicated by the reception of air in our lungs, impregnated with contagious matter. The influence of the constant respiration of air in any degree impure, is fully evinced in the pallid countenances and languid frames of those who live in confined and ill-ventilated places; and the health of all classes of society suffers precisely in proportion to the susceptibility of their constitutions, and according to the greater or less impurities of the air which they habitually respire.

Of the offensive nature of animal effluvia, the senses of every one who enters a crowded assembly, must immediately convince him. When, therefore, we reflect on the state of the air which we breathe in churches, theatres, schools, and all crowded assemblies; and when we consider the amount of the exhalations emitted by each individual, and the very offensive nature of those emitted by many; and when, on the other hand, we take into consideration the importance of air to life, and the great quantity of this fluid which we daily respire, we must be naturally led to the adoption of such measures as would secure in our private dwellings, as well as in our public buildings, a full and unintermitting supply of fresh atmospheric air.

It is curious to observe the influence of habit, in reconc.ling us to many practices which would otherwise be considered in the highest degree offensive. Thus, while, with a fastidious delicacy, we avoid drinking from a cup which has been already pressed to the lips of our friends, we feel no hesitation in receiving into our lungs an atmosphere contaminated by the breath and exhalations of every promiscuous assembly.

"Were once the energy of air deny'd,

The heart would cease to pour its purple tide
The purple tide forget its wonted play,

Nor back again pursue its curious way."

The next Subject of Curiosity we shall consider, is, THE HAIR OF THE HEAD.

If we consider the curious structure, and different uses o the hair of our heads, we shall find them very well worth our attention, and discover in them proofs of the wisdom and power of God.

In each entire hair we perceive with the naked eye, an oblong slender filament, and a bulb at the extremity thicker and more transparent than the rest of the hair. The filament forms the body of the hair, and the bulb the root. The large hairs have their root, and even part of the filament, er closed in a small membraneous vessel or capsu e. The size of this

sheath is proportionate to the size of the root, being always rather larger, that the root may not be too much confined, and that some space may remain between it and the capsule. The root or bulb has two parts, the one external, the other mternal. The external is a pellicle composed of small laminæ; the internal is a glutinous fluid, in which some fibres are united; it is the marrow of the root. From the external part of the bulb proceed five, and sometimes, though rarely, six small white threads, very delicate and transparent, and often twice as long as the root. Besides these threads, small knots are seen rising in different places; they are viscous, and easily dissolved by heat. From the interior part of the bulb proceeds the body of the hair, composed of three parts; the external sheath, the interior tubes, and the marrow.

When the hair has arrived at the pore of the skin through which it is to pass, it is strongly enveloped by the pellicle of the root, which forms here a very small tube. The hair then ushes the cuticle before it, and makes of it an external sheath, which defends it at the time when it is still very soft. The rest of the covering of the hair, is a peculiar substance, and particularly transparent at the point. In a young hair this sheath is very soft, but in time becomes so hard and elastic, that it springs back with some noise when it is cut. It preserves the hair a long time. Immediately beneath the sheath are several small fibres, which extend themselves along the hair from the root to the extremity. These are united amongst themselves, and with the sheath that is common to them, by several elastic threads; and these bundles of fibres form together a tube filled with two substances; the one fluid, the other solid; and these constitute the marrow of the hair. The wonders of creating power are seen in every thing, even in the hair that adorns our surface.

All are but parts of one stupendous whole,
Whose body Nature is, and God the soul.
That, chang'd thro' all, and yet in ail the same ;
Great in the earth, as in th' ethereal frame;
Warms in the sun, refreshes in the breeze,
Glows in the stars, and blossoms in the trees.
Lives thro' all life, extends thro' all extent,
Spreads undivided, operates unspent ;
Breathes in our soul, informs our mortal part,
As full, as perfect, in a hair as heart;
As full, as perfect, in vile Man that mourns,
As the rapt seraph that adores and burns:
To him no high, no low, no great, no small;
He fills, he bounds, connects, and equals all.

We shall now introduce to our readers some Ancient and dern Opinions respecting the Hair.

The ancients held the hair a sort of excrement, fed only

with excrementitious matters, and no proper part of a livin body. They supposed it generated of the fuliginous parts o the blood, exhaled by the heat of the body to the surface, and then condensed in passing through the pores. Their chief reasons were, that the hair being cut, will grow again, even in extreme old age, and when life is very low; that in hectic and consumptive people, where the rest of the body is continually emaciating, the hair thrives; nay, that it will even grow again in dead carcases. They added, that hair does not ed and grow like the other parts, by introsusception, i. e. by juice circulating within it, but, like the nails, by juxtaposition. But the moderns are agreed, that every hair properly and truly lives, and receives nutriment to fill it, like the other parts; which they prove hence, that the roots do not turngrey in aged persons sooner than the extremities, but the whole changes colour at once; which shews that there is a direct communication, and that all the parts are affected alike. In strict propriety, however, it must be allowed, that the life and growth of hairs is of a different kind from that of the rest of the body, and is not immediately derived therefrom, or reciprocated therewith. It is rather of the nature of vege tation. They grow as plants do, or as some plants shoot from the parts of others; from which, though they draw their nourishment, yet each has, as it were, its distinct life and economy. They derive their food from some juices in the body, but not from the nutritious juices of the body; whence they may live, though the body be starved. Wulferus, in the Philosophical Collections, gives an account of a woman buried at Nurenberg, whose grave being opened forty-three years after her death, hair was found issuing forth plentifully through the clefts of the coffin. The cover being removed, the whole corpse appeared in its perfect shape; but, from the crown of the head to the sole of the foot, covered over with thick-set hair, long and curled. The sexton going to handle the upper part of the head with his fingers, the whole fell at once, leaving nothing in his hand but a handful of hair: there was neither skull nor any other bone left: yet the hair was solid and strong. Mr. Arnold, in the same collection, gives a relation of a man hanged for theft, who, in a little time, while he yet hung upon the gallows, had his body strangely covered over with hair.

Before we dismiss this subject, we shall give the following curious Instances of the Internal Growth of Hair.

Though the external surface of the body is the natural place for hairs, we have many well-attested instances of their being found also on the internal surface. Amatus Lusitanus mentions a person who had hair upon his tongue. Pliny and Valerius Maximus say, that the heart of Aristomenes the

Messenian, was hairy. Callus Rhodiginus relates the same of Hermogenes the rhetorician; and Plutarch, of Leonidas king of Sparta. Hairs are said to have been found in the breasts of women, and to have occasioned the distemper called trichiasis; but some authors are of opinion, that these are small worms, and not hairs. There have been, however various and indisputable evidences of hairs found in the kidneys, and voided by natural discharge. Hippocrates says, that the glandular parts are the most subject to hair; but bundles of hair have been found in the muscular parts of beef, and in parts of the human body equally firm. Hair has been often found in abscesses and imposthumations. Schultetus, open ing the abdomen of a human body, found twelve pints of water, and a large lock of hair swimming loosely in it. It has, however, been found on examination, that some of the internal parts of the body are more subject to an unnatural growth of hair than others. This has long been known to anatomists; and many memorable instances have been recorded by Dr. Tyson, and others. In some animals, hairs of a considerable length have been discovered growing in the internal parts; and on several occasions, they have been found lying loosely in the cavities of the veins. There are instances of mankind being affected in the same manner. Cardan relates, that he found hair in the blood of a Spaniard; Slonatius, in that of a gentlewoman of Cracovia; and Schultetus declares, from his own observation, that those people, who are afflicted with the plica polonica, have very often hair in their blood.

We shall, in the next place, call the reader's attention to some CURIOUS REMARKS CONCERNING THE BEARD.

A beard gives to the countenance a rough and fierce air suited to the manners of a rough and fierce people. The same face without a beard appears milder; for which reason, a beard becomes unfashionable in a polished nation. Demosthenes, the orator, lived in the same period with Alexander the Great, at which time the Greeks began to leave off beards. A bust, however, of that orator, found in Herculaneum, has a beard, which must either have been done for him when he was young, or from reluctance in an old man to a new fashion. Barbers were brought to Rome from Sicily, the 454th year after the building of Rome. And it must relate to a time after that period, what Aulus Gellius says, that people accused of any crime were prohibited to shave their beards till they were absolved. From Hadrian downward, the Roman empercrs wore beards. Julius Capitolinus reproaches the Emperor Verus for cutting his beard at the instigation of a concubine. All the Roman generals wore beards in Justinian's time. The pope shaved his beard, which was held a

manifest apostasy by the Greek church, because Moses, Jesus Christ, and even God the Father, were always drawn with beards by the Greek and Latin painters. Upon the dawn of smooth manners in France, the beaus cut the beards into shapes, and curled the whiskers. That fashion produced a whimsical effect: men of gravity left off beards altogether. A beard, in its natural shape, was too fierce even for them; and they could not, for shame, copy after the beaus. This accounts for a regulation, anno 1534, of the University of Paris, forbidding the professors to wear a beard.

Now follows, A curious account of WOMEN with Beards.

Of women remarkably bearded we have several instances. In the cabinet of curiosities at Stutgard, in Germany, there is the portrait of a young woman, called Bartel Graetje, whose chin is covered with a very large beard. She was drawn in 1787, at which time she was but twenty-five years of age There is likewise, in another cabinet, the same portrait of her when she was more advanced in life, but likewise with a beard. It is said, that the Duke of Saxony had the portrait of a poor Swiss woman taken, remarkable for her long bushy beard; and those who were at the carnival of Venice in 1726, saw a female dancer astonish the spectators, not more by her talents, than by her chin covered with a black bushy beard. Charles XII. had in his army a female grenadier, who wanted neither courage nor a beard to be a man. She was taken at the battle of Pultowa, and carried to Petersburg, where she was presented to the czar, in 1724: her beard measured a yard and a half. We read in the Trevoux Dictionary, that there was a woman seen at Paris, who had not only a bushy beard on her face, but her body likewise covered all over with hair. Among a number of other examples of this nature, that of the great Margaret, the governess of the Netherlands, is very remarkable. She had a very long stiff beard, which she prided herself on: and being persuaded that it contributed to give her an air of majesty, she took care not to lose a hair of it. It is said, that the Lombard women, when they were at war, made themselves beards with the hair of their heads, which they ingeniously arranged on their cheeks, that the enemy, deceived by the likeness, might take them for men. It is asserted, after Suidas, that in a similar case the Athenian women did as much. These women were more men than our Jemmy-Tessamy countrymen. About a century ago, the French ladies adopted a mode of dressing their hair in such a manner, that curls hung down their cheeks as far as their bosom. These curls went by the name of whiskers. This custom, undoubtedly, was not invented after the example of the Lombard women, to fight men.
