you had to stand at the bed and had seen the suffering and de- 
spair of the patients, and found that the worms were eating them 
up, you would not think so. All these cases occurred in the 
month of September.—/red. Humbert, M. D., F. C.S. 
[Upon this communication Dr. C. V. Riley says, that the insect 
here referred to as attacking a human subject in Illinois, “is the 
Lucilia macellaria of Fabricius, the injuries of which to different 
animals are well known in the South and West, where the larva 
is called the ‘screw-worm.’ I have repeatedly endeavored to 
obtain the true parent of this worm. Dr. Humbert’s communica- 
tion is most interesting, but the specimens yet more so, as the 
flies he forwards are the first that have positively been bred from 
the: larve known as ‘screw-worms,’ and they confirm the above 
determination of the species. The larve agree with others which 
I have from Texas, taken from the root of the ear of a hog which 
had been bitten by a dog.”]—Froc. U. S. Nat. Mus., Sept, 1883,
