176 EETUKN TO ENGLAND : AND VISIT TO PARIS 



impudence to ask for Hepat. etc. in the same letter as he 

 so coolly boasts his guilt and shame. I have promised, 

 however, and shall send them, * sans lettre ' however. I shall 

 drop cher confrere quietly, as our friend Berkeley has H.; and 

 place him * inter eos maxime vitandos.' . . . 



One of these Southern Algae, contributed by Darwin, was 

 difficult to identify, and called forth the following to Harvey, 

 November 11, 1844.
