The student of anatomy is perfectly well aware 

 that there is not a single organ of the human body 

 the structure of which does not vary, to a greater 

 or less extent, in different individuals. The skele- 

 ton varies in the proportions, and even to a certain 

 extent in the connections, of its constituent bones. 

 The muscles which move the bones vary largely 

 in their attachments. The varieties in the mode 

 of distribution of the arteries are carefully classi- 

 fied, on account of the practical importance of a 

 knowledge of their shiftings to the surgeon. The 

 characters of the brain vary immensely, nothing 

 being less constant than the form and size of the 

 cerebral hemispheres, and the richness of the con- 

 volutions upon their surface, while the most 

 changeable structures of all in the human brain are 

 exactly those on which the unwise attempt has 

 been made to base the distinctive characters of 

 humanity, viz. the posterior cornu of the lateral 

 ventricle, the hippocampus minor, and the degree 

 of projection of the posterior lobe beyond the cere- 

 bellum. Finally, as all the world knows, the hair 

 and skin of human beings may present the most 

 extraordinary diversities in colour and in texture. 



So far as our present knowledge goes, the ma- 

 jority of the structural varieties to which allusion 

 is here made, are individual. The ape-like ar- 

 rangement of certain muscles which is occasion- 

 ally met with * in the white races of mankind, is
