Italian buffalo " 1 never to use bis bonis; be 



u tremendous blow with his convex forehead, and then 

 tramples on bis fallen enemy with his knees." Darwin 

 also says that male quadrupeds with tusks use them in a 

 variety of ways: thus the boar "strikes laterally and up- 

 ward, the musk-deer with feci downward," wh 

 the walrus can strike either upward, downward, or side- 

 ways with equal dexterity. 



Thr males are usually larger when th anydiffi 



in size; this is seen in the oared seals, in the ox, Indian 

 buffalo, and the American bis »n, as well as the lion. The 

 mane of the latter adds »f greater weight 



and bulk, and Darwin at the lion's mane "forms 



od defence against the one danger to which he is liable 

 — namely, the attacks of rival lions." As regards distil - 

 tions in color, male ruminants are most liable to exhibit 

 them. In the Derbyan eland the bodj ler, the neck 



much blacker, and the white band separating these col - 

 broader than in the females. In the Cape eland the ma 

 is slightly darker than the female. In the Indian black- 

 huek the male is very dark, almost black, while the female 

 fawn-colored: male antelopes are blacker than the female. 

 The Banteug bull is almost black, while the cow is of a 

 bright dun. Among the lemurs the male of Lemur n 

 s coal-black, while the female is reddish yellow. The 

 \es of monkeys differ much in coloration. Certain male 

 - als. bats. rats, and squirrels have brig olors than in 



the opposite sex. On the other hand, the female Rhes - 

 monkey is adorned with a brilliant red naked ring around 

 the tail; this is wanting in the male, which, however, - 

 larger, with larger canines, more bushy whiskers and eye- 

 brows; and Darwin - that in monkeys the mal< 

 ally differ from the females in "the development of the 

 beard, whiskers, and mane." 



The vocal organs of mammals are. in general, constructed 

 on the same type. The larynx is formed by a modification
