The fawns continue with the old ones eight or nine months, and soon after separating their horns begin to appear, simple knobs without antlers; these they shed at the latter end of autumn, and have them renewed during the winter; differing in this from the stag, who sheds them in spring, and renews them in the summer. Several causes contribute to produce these different effects. In summer, the stag takes a great quantity of nourishment, and grows very fat; in the rutting season he exhausts himself so much that the whole winter is not more than sufficient to effect his recovery. At this time, so far from there being a superabundance of nourishment, he experiences an absolute scarcity, and of coarse his horns cannot sprout till spring, when his nourishment is again superabundant. The roe-buck, on the contrary, who never exhausts himself so much, has less occasion for repair; and as he is never incumbered with fat, nor any change is made in him during the time of the rut, being always nearly the same, so he has, at all times, the same superfluity; so that even in winter, and soon after the rut, he sheds and renews his horns; and it appears that these productions, which may be termed vegetable ones, are formed of an organic and superfluous matter, though still imperfect, and mixed with inanimate particles; since in their growth and substance they preserve the vegetable qualities whereas the seminal fluid, whose production is not so early, is a matter altogether organic, divested of inanimate particles, and assimilated to the body of the animal. When the roe-buck has completely repaired his horns, he rubs them against the trees in the same manner as the stag, in order to strip them of the skin with which they are covered: and this he generally does about March, before the trees begin to shoot; hence it is not the sap of the wood which tinges the horns of the buck; yet they are brown in those that have brown hair, and yellow when the animal is red, consequently the colour of the horns arises solely, as has already been remarked, from the nature of the animal, and the impression of the air. The second horns of the roe-buck have generally two or three antlers on each side; the third have three or four; the fourth, five; and they seldom have more; and the old ones are distinguished by the thickness of their stems. While their horns are soft they are extremely sensible of pain. Of this I witnessed a striking proof. With a ball from a gun the young shoot of a roe-buck's horn was taken clear off, and by which he was so stunned that he fell down as if he were dead; the shooter, who was near, seized him by the foot, but the animal suddenly recovering his strength and feeling, dragged the man, though very strong and vigorous, above thirty paces, till he dispatched him with a hanger; it was then found that he had received no other wound than that of the hanger, and what the ball had made in striking the horn. It is also well known that flies
