 metaphors you would make from it ! I wish some one would 

 keep a lot of the most noisy monkeys, half free, and study

A book has just appeared here which will, I suppose, 

 make a noise, by Bishop Colenso,f who, judging from ex- 

 tracts, smashes most of the Old Testament. Talking of 

 books, I am in the middle of one which pleases me, though

 of the Amazons Valley " (' Linn. Soc. Trans.' xxiii., 1862), in which the now 

 familiar subject of mimicry was founded. My father wrote a short review 

 of it in the 'Natural History Review,' 1863, p. 219, parts of which occur 

 almost verbatim in the later editions of the ' Origin of Species.' A strik- 

 ing passage occurs showing the difficulties of the case from a creationist's 

 point of view : — 



" By what means, it may be asked, have so many butterflies of the Ama- 

 zonian region acquired their deceptive dress ? Most naturalists will answer
