38 HOMO V. DARWIN. 



of animals " differ in no respect " from one another, then he 

 must also believe that it is only because of the different 

 conditions under which they are developed, that different 

 creatures are produced from them. Under the same con- 

 ditions the result would be the same, and all born creatures 

 might be donkeys, monkeys, or men. It follows, also, that 

 in the germ, all creatures are not only similar, but abso- 

 lutely identical. Originally, there is no difference between 

 a man and a rhinoceros, or between a chimpanzee and a sheep. 



Lord C. Mr. Darwin will doubtless think of this, end 

 will, perhaps, modify his language in subsequent editions 

 of his work. 



Darwin. My Lord, " as some readers of my book may 

 never have seen a drawing of an embryo, I have given one of 

 man, and another of a dog, at about the same early stage of 

 development, carefully copied from two works of undoubted 

 accuracy." (Vol. i. pp. 14, 15.) 



Lord C. (Examining the drawing.) The difference is 

 certainly quite as striking as the resemblance. Any 

 intelligent child could indicate the points of dissimi- 

 larity. 



Homo. And yet, my Lord, the ovules from which such 

 developments proceed, " differ in no respect " from one 

 another. 



Darwin. My Lord, " it would be superfluous on my part 

 to give a number of borrowed details, showing that the 

 embryo of man closely resembles that of other mammals. 

 It may, however, be added, that the human embryo likewise 

 resembles, in various points of structure, certain low forms 

 when adult." (Vol. i. p. 1G). 



Lord C. I suppose that no one who has looked into the 

 matter will deny that, in the germs and embryonic be- 

 ginnings of all vertebrate m-.'iturcs, there are points of
