24 The Descent of Man 



process of his development. He points out (vol. i. p. 11) not 

 only the close similarity even of cerebral structure between 

 man and apes, but also how the ^ame animals are ' liable to 

 many of the same non-contagious diseases as we are ; thus 

 Kengger, who carefully observed for a long time the Cebus 

 Azaroe in its native land, found it liable to catarrh, with the 

 usual symptons, and which when often recurrent, led to 

 consumption. These monkeys suffered also from apoplexy, 

 inflammation of the bowels, and cataract in the eye. 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.' He also tells us of 

 baboons which, after taking too much beer, ' on the following 

 morning were very cross and dismal, held their aching heads 

 with both hands, and wore a most pitiable expression : when 

 beer or wine w^as offered them, they turned away with 

 disgust, but relished the juice of lemons.' He notices, 

 besides, the process of development in man with the 

 transitory resemblances it exhibits to the immature con- 

 ditions of other animals, and he mentions certain muscular 

 abnormalities. 



Mr. Darwin also brings forward an observation of Mr. 

 Woolner, the sculptor, as to a small projection of the helix or 

 outermost fold of the human ear, which projection ' we may 

 safely conclude 'to be ' a vestige of formerly pointed ears — 

 which occasionally re-appears in man ' (vol. i. p. 23). Very 

 many other interesting facts are noted which it would be 

 superfluous here to recapitulate. It is, however, in connection 

 with man's bodily structure and its resemblances, that we 

 have observed slight errors on the part of Mr. Darwin, which 

 it may be as well to point out ; though it should be borne 

 in mind that he does not profess to be in any sense an
