280 Edward’s Industry. [CHAP. Xv. 
then you will find that all my time and attention have been 
occupied with the isopods. So do try and look out for 
some of these, and leave the Amphipods alone for a little 
while.” 
And again: “Please never apologize for writing to me 
about natural history. We have now been such long cor- 
respondents, that. unless I hear from you now and then, I 
begin to fancy myself forgotten. Your letters always give 
me pleasure. The crustacea that you speak of is a Vibilia,

ing the day, with only a few hours in the early morning 
and a few hours at night which he was able to employ in
