1 2 THE DESCENT OF MAN. [Part I. 



The younger ones when shedding their milk-teeth often 

 died from fever. Medicines produced the same effect on 

 them as on us. Many kinds of monkeys have a strong 

 taste for tea, coffee, and spirituous liquors : they will also, 

 as I have myself seen, smoke tobacco with pleasure. 

 Brehm asserts that the natives of nortlieastern Africa 

 catch the wild baboons by exposing vessels with strong 

 beer, by which tliey are made drunk. He lias seen some 

 of these animals, which he kept in confinement, in this

 when beer or wine was offered them, they turned away 

 with disgust, but relished the juice of lemons.^ An Amer-

 would never touch it again, and thus was wiser than many

Man is infested with internal parasites, sometimes 

 causing fatal effects, and is plagued by external parasites, 

 all of which belong to the same genera or families Avith 

 those infesting other mammals. Man is subject like other 

 mammals, birds, and even insects, to that mysterious law, 

 which causes certain normal processes, such as gestation, 

 as well as the maturation and duration of various diseases, 

 to follow lunar periods.^ His wounds are repaired by the 

 same process of healing ; and the stumps left after the

 fering from tertian ague.
