RUDIMENTS.

thus 
scattered over the body are the rudiments of the 
Uu iform hairy coat of the lower animals. This view is 
gendered all the more probable, as it is known that fine, 
10r b ail d pale-coloured hairs on the limbs aud other 
I’Hrts of the body occasionally become developed into 
iickset, long, and rather coarse dark hairs,” when ab- 
nor ma Hy nourished near old-standing inflamed surfaces . 29 
^ f am informed by Mr. Paget that persons belonging 
0 the same family often have a few hairs in their eye- 
J1 °ws much longer than the others: so that this slight 
Peculiarity seems to be inherited. These hairs appa- 
r ently represent the vibrissa:, which are used as organs 
0 to nch by many of the lower animals. In a young 
j '| m panzee I observed that a few upright, rather long, 
ail- s, projected above the eyes, where the true eyebrows, 
1 present, would have stood. 
. e fine wool-like hair, or so-called lanugo, with 
rch the human foetus during the sixth month is 
. llc kly covered, offers a more curious case. It is first 
y vdoped, during the fifth month, on the eyebrows and 
,ie e, and especial])' round the mouth, where it is much 
( l,l ger than that on the head. A moustache of this kind
