MEXICO AND INDIA 193 



America had excited his interest in the old civilizations 

 of this hemisphere. In the following letter, when speak-

 bulk of the Plates for that memoir done. There are now 

 fourteen finished and ten more to make. This will make 

 quite a dose even after the Challenger Echini. In mean-

 Young Fishes, which has been under way in some shape

 Murray's, but I don't want you to have a copy from 

 anybody but myself, and hope you will put it on your 

 shelves, and when you look at it sometimes think how
