96 ANTHROPOID APES. 



a close embrace. If they were separated, their eyes 

 became bright and restless, and they again sought 

 to embrace each other while uttering plaintive cries. 

 On tickling one of the animals under the chin, it 

 made a most absurd grimace, and its eyes brightened, 

 as Martin has observed in similar cases. The eyes 

 of the gibbons which I have observed had a 

 thoroughly mild and placid expression, rarely 

 animated by any fire. 



The instance we have mentioned of hairless 

 Australians is the more remarkable since these 

 aborigines are for the most part distinguished for 

 their luxuriant growth of hair. The Australian 

 blacks and the Ainos of Yedo are, as a rule, perhaps 

 the most hairy races in the world. It is known, 

 however, that in all countries and climates excep- 

 tional cases are found of individuals whose bodies 

 are wholly or partially covered with hair, and these 

 conditions sometimes affect whole families. Inte- 

 resting historical and morphological researches 

 respecting these hairy men have recently been made 

 by von Siebold, Ecker, Virchow, Bartels, and Orn- 

 stein. In many of these cases we are presented 

 with decidedly brute-like phenomena. The Mexican 

 woman Julia Pastrana displays the strongest resem- 

 blance to apes. Other hairy men remind us at the 

 first glance of some of the canine species. In all 

 races the women are less hairy than the men. Dar- 

 win states that in the females of some species of 

 apes the under side of the body is less hairy than in 

 the males, and this is also the case with anthropoids, 

 especially with the chimpanzee.
