Kitchen Parker on Mammalian Descent 287 



perfect teats, but their young are born so early that they 

 derive no direct nourishment from the mother until they are 

 placed on the teat. 



" (3) Euthevia. — These forms are the highest, and their young 

 do derive direct nourishment from the mother for a consider- 

 able time before birth — before they are nourished by milk. 

 In this group we have moles and men, and all the forms that 

 lie between these two extremes. I shall speak of the mole as 

 a low Eutherian, of man and of his horse as high Eutheria. 

 There are at present three groups of labourers working at the 

 mammalia, as, indeed, at other types also ; these are : — 



" (1) The Zoologists. These study the finished form, 

 habits, and distribution of the various types, in the present 

 state of the planet. 



" (2) The Palaeontologists. These study the fossil remains 

 of the extinct forms, and their past distribution. 



" (3) The Embryologists. These men are working out the 

 development of this or that type, following it through the 

 various stages of the history of its life." 



The author from whom we have taken the above was not 

 only one of the most highly skilled naturalists of his day, but 

 one of the most genial and open-minded of men. He was 

 both reverential and religious, and remained to the end of his 

 life a Wesleyan Methodist. He was accustomed to assert 

 that the idea of evolution was not so new as many seemed to 

 think it, and would clench his argument and shock his friends 

 by remarking that Job showed some perception of it when he 

 wrote, " I said to the worm, thou art my mother." The 

 quotation which we have given is a good specimen of 

 Professor Kitchen Parker's style, at once picturesque in 

 manner and profound in detail.
