Hair FRomM THE Stomacu.—Dr. F. A. Vandyke told us of a case of a female lunatic, who 
extracted her hypogastric hair and swallowed it. Upon a post mortem examination, had 
for another purpose, they were found in her stomach in the form of a ball. 
We have in our cabinet quite a variety of hair-balls extracted from the stomach of Rumi- 
nants, many of which we have examined.

Dr. Rogers, speaking of these hair-balls found in the stomach and alimentary canal of 
Cows, &c., says that the animals lick the hairs from the skin and swallow them with the 
saliva; that they concrete, forming a ball. (Prin. and Prac. of Med., 1844, p. 934.) In 
Youatt’s Essay on Sheep, in Lib. of Usf. Know., 439, will be found an account of these 
balls by the name of Bezeors or Calculi in the abemasum of these animals. From a note 
affixed it seems that they are found likewise in every species of Deer and Antelope, in the 
Elephant, the Rhinoceros,-the Porcupine and some other animals. 
Hair on the Tongue.—The second volume of the Medical Examiner, 1846, p. 266, 
mentions several cases of hairy productions on the surface of the tongue. (Med. Times, 
v. 18, p. 148.) 
Or Pine wHicH APPEARS TO GRow ouT oF THE INTERIOR SURFACE OF THE SkKIN.— 
Some of the skins of the lower animals, tanned with the pile on, have filaments which 
appear to be growing out of the zterior surface of the skin. The first one upon which 
we noticed this phenomenon was the skin of an Otter. It was about one foot in length 
and about seven inches wide, and there was a spot near the centre, of about five by three 
inches, where the pile grew sparsely upon the inner surface. The animal was, as usual, 
covered with a dense, fine wool, with long hairs above, but none but the hairs were to be seen 
on the inner surface. The hairs on the back of the animal have the usual acute angle, 
which obliged them to lie smoothly, inclining from the head towards the tail; but these
