intended for the Recueil Historique, and a study of the 

 sheep-tick, earlier than that on the goat-moth. He did 

 not live to carry out this intention, but long after his death 

 the papers, illustrated by fifty-four plates, were published 

 in the Memoir es du Museum} The plates deal with the 

 sheep-tick ; Mallophaga (Anoplura) ; mites and ticks ; 

 the house-spider ; Dytiscus, Hydrophilus and some other 

 beetles ; the life-histories of various Diptera and Lepi-

 student of life-histories finds valuable details in these 

 posthumous memoirs, but they are too difficult and too 

 dry for ordinary readers.^

 painter and engraver, and became expert in the fashion-
