 would be liable to' the same fate. 



There are some startling facts on the subject of parasitic 

 insects, to be found in the " Monographia Anoplurorum Bri- 

 tanniae," by Mr. Henry Denny, Curator to the Leeds Philoso- 

 phical Society, a work which, although with a dog-latin title, 

 that has doubtless limited its circulation, is written in such 

 plain and truthful English, as to make the flesh creep on one's 

 bones. It is not easy to enjoy uninterrupted slumber the night 

 after reading Mr. Denny's Monograph. 



" The author has had to contend with repeated rebukes from 

 his friends for entering upon the illustration of a tribe of in- 

 sects whose very name was sufficient to create feelings of dis- 

 gust. ' Why not take up some more interesting or popular de-

 to him. He considered, however, that if he wished to render 

 any service to science, he must not consult popular taste or 

 ephemeral fashion, but must take a page from that part of the 

 great Book of Nature less generally read, and consequently 

 less understood and appreciated, by the world at large." 



The number and variety of species given is frightful ; some 

 of those which infest Poultry are : 



" Goniocotes hologaster (Louse of the Domestic Fowl). 



<( Goniodes falcicbrnis (Louse of the Peacock). This beauti- 

 ful (!) parasite is common upon the Peacock, and may be 

 found after the death of the bird congregated in numbers 

 about the base of the beak and crown of the head. During 

 the year 1827, three or four specimens of Pavo cristatus hav- 

 ing passed through my hands, upon each of which I observed, 

 for the first time, several examples of the large and well-marked 

 parasite of this bird, the Goniodes falcicornisj I was induced to 

 examine whatever other species of birds, &c., might come in 

 my way, to ascertain whether great diversity in size or ap- 

 pearance existed between the parasites of different species or
