350 LESSONS FKOM NATUEE. [CHAP. XI. 



nation occurs where Mr. Wright tells us it may be that the 

 rattle will serve all the purposes that drums, trumpets, and 

 gongs do in human warfare. The swaying the body and 

 vibrating tongue of most snakes, and the expanding neck, 

 and the hood of the cobra, may serve as banners. I must 

 submit to be blamed for my poverty of resources by one 

 whose reason is supplemented by so active an imaginative 

 faculty. 



&quot; In reviewing my chapter on Independent Similarities of 

 Structure, Mr. Wright replies to my remarks as to 



An objection 



mathema&quot; a characters in placental and implacental mammals 

 which are similar, indeed, but not similar through 

 inheritance : 



&quot; Our author .... has incautiously left a hostile force in his 

 rear. He has claimed in the preceding chapter for Natural Selection 

 that it ought to have produced several independent races of long- 

 necked Ungulates, as well as the giraffe ; so that, instead of pursuing 

 his illustrations any further, we may properly demand his surrender. 



&quot; But such a demand would be futile ; the cases, in fact, 

 being quite dissimilar. With regard to the Ungulates we 

 have the action of similar causes upon organisms which, by 

 the hypothesis, are closely alike ; in the case of the placental 

 and implacental beasts we have similar causes acting upon 

 organisms which, by the hypothesis, are fundamentally 

 different. 



&quot; Certainly, then, if Mr. Darwin s theory is true, we ought 

 to have, in the first case, many similar forms developed ; and 

 we ought not to have such in the second case. It is just the 

 difference between adding equals to equals and equals to 

 unequal s. 



&quot; Passing over Mr. Chauncey Wright s exposition * of our 

 Lord s discourse to Nicodernus (in which, I fear, few Dar- 



* &quot; Mr. Wright speaks of the symbols water and the Spirit, which Christians 

 have ever since worshipped. It is certainly difficult to remember the mul 

 titude of sects which have appeared since the dawn of Christianity, but the 

 existence of any body of loafer-worshippers strikes me as a novelty.
