There is such a crown on a cow’s face, between the eyes, 
and the circular growth is often strongly marked. The hair 
below—on the nose—grows downwards to the nostrils ; the hair 
above—on the forehead—grows up and back to the horns. The 
hair grows the same in a cat, but there is no definite crown.* 
Darwin has remarked on the growth of the hair on the 
arms—that it grows upwards to the elbow on the hinder part 
of the forearm; and he suggests “that this is due to a habit 
of Man’s ancestors sitting with their hands over their heads 
to keep off rain, as some monkeys do who have the hair arranged 
in the same way.” 
In quadrupeds the direction of the hair on the limbs 
should be downwards, in obedience to flow of rain; but on the 
forearm of a dog and a pig there is a very similar arrangement 
to what obtains in man—in the former, in fact, quite a slight 
upward turn at the equivalent of the elbow.t 
It may be that Darwin is to a certain extent correct in 
his surmise, but the explanation hardly seems sufficient. It is 
necessary to explain the direction of the hair on the dog’s and 
pig’s legs; and rain does not seem the cause for this. t 
Further, in Man the downward growth of the hair on the 
inside of the arm and back of the hand does not accord with 
this idea of the hands clasped over the head, for in such a 
position the hair ought to grow on the backs of the hands in 
the same direction as on the forearm. 
[ * In the Bonnet monkey there is a very distinct crown on the back of the 
head ; on the forehead and scalp the thin hair falls sideways from a central 
parting. ] 
[ft There is on the forearm of Cebus fatuellus, Capuchin monkey, the same 
arrangement of hair as in Man. | 
[ { Motion through the air having more effect than rain, on account of its 
greater frequency, or any habits of seeking shelter might be a cause. |
