At a late meeting of the British Association (1862), Pro- 

 fessor Owen read a paper "On the brain and limb characters 

 of the Gorilla as contrasted with those of Man," * in which, 

 without alluding to the disclaimer by the Dutch anatomists 

 of their defective plates, now so widely circulated in Eng- 

 land, he observes that in the gorilla the cerebrum "extends 

 over the cerebellum, not beyond it." This statement, al- 

 though slightly at variance with one published the year be- 

 fore (1861) by Professor Huxley, who maintains that it does 

 })roject beyond, is interesting as correcting the description 

 of the same brain given by Professor Owen in that year, in 

 a lecture to the Royal Institution, in which a considerable 

 jjurt of the cerebellum of the gorilla was represented as un- 

 covered. f In the same memoir it is remarked that in the 

 Maimon Eaboon the cerebrum not only covers but " extends 

 backwards even bej^ond the cerebellum."| This baboon, 

 therefore, possesses a posterior lobe, accoi'ding to every de- 

 scription yet given of such a lobe, including a new definition 

 of the same lately proposed by Professor Owen. For the 

 ])Osterior lobe was formerly considered to be that part of the 

 cerebrum which covers the cerebellum, whereas Professor 

 Owen defines it as that part which covers the posterior third 

 of the cerebellum, and extends beyond it.§ 



We may, therefore, consider the attempt to distinguish the 

 brain of Man from that of the ape, on the ground of newly- 

 discovered cerebral characters, presenting differences in kind, 

 as virtually abandoned by its originator, and if the sub-class
