LIFE-HISTORT OP FILABIA BANCROFT!. 



the name of Lewis will henceforth tower above all others in this 

 connexion, and Bancroft would, I am sure, he the last to dispute 

 the well-earned prerogative of Lewis. If my record is approxi- 

 mately correct, the dates of discovery will stand pretty much as 

 follows : — 



1. "WucHERER, 1866. — Probably embryos of StrongylidaB 

 (Leuckart) ; Vers du Bresil (Wucherer ; Davaine) ; Filaria 

 wiichereri, suggested, conditionally, in this memoir (Cobbold). 



2. Salisbijrt, 1868. — Trichina cystica (Salisbiu-y) ; nematode 

 eggs and embryos (Cobbold). 



3. Lewis, 1870. — Worms that seem to belong to the Filaridce 

 (Busk). 



4. Cobbold, 1870. — Embryos of a minute nematode supposed 

 to infest the urinary passages.

 AnguiUula (Sonsino). 



10. O'Neill, 1875. — Filariose dermatJiemica, from craw-craw

11. Manson, 1875 (?). — Filaria worm in connexion with 

 chyluria, &c. (Manson). 



12. Bancroft, 1876 (spring of). Filarice from human blood 

 (Bancroft; Eoberts ; Cobbold).

 Lewis, and Bancroft (Cobbold). 



The above is the nearest approximation to a correct chrono- 

 logical record that I can offer. With one or two exceptions the 

 dates refer to the actual periods of discovery. In the exceptional
