 acquired vitality enough to annoy him 

 while in contact with the sound flesh. 

 So soon as thev came in contact with

Dr. Britton forwarded to me speci- 

 mens of the fly, bred as above stated, 

 which I identified as LiiciliamaceUaria 

 Fab. In order, however, that there 

 might be no possibility of error, I sub- 

 mitted them to Dr. S. W. Williston, of 

 New Haven, Conn., who corroborated 

 tliis determination and furnished the 

 f)llowing notes concerning the species: 

 ■■The specimens arc evidently Lucilia 

 ( Campsomyia) macellaria Fab., a fly 

 common from tlie Argentine Republic 

 to Canada, and which from its varia- 

 tions has probably received more spe- 

 cific names (20!) than any other Amer- 

 ican fly. It belongs to the Muscidac 

 (true) and is not far from Musca. Their 

 hominivorous propensities have gained 

 for them the synonyms of Lucilia 

 iiominivorax Coquerel, and L. homi- 

 iiivorus Cenil (S. America)." 



In the Peoria (111.) Medical Monthly 

 for February, 1SS3, Dr. Joshua Rich- 

 ardson, of Moravia, Iowa, has an article 

 upon •' The screw-fly and its ravages," 

 from which I make the following ex- 

 tracts: " While travelling in Kansas 

 in the latter part of last August a citizen 

 of this place had the misfortune to 

 receive while asleep a deposit of eggs 

 from this flv. lie had been troubled 



for vcars with catarrh, hence the attrac- 

 tion to the fly. He returned home a 

 few days after the accident and shortly 

 after began complaining of a bad cold. 

 Growing rapidly worse, 1 was called 

 to attend him. Monday, my first day, 

 his appearance was that of a man 

 laboring imder a severe cold. Had 

 slight congestion of the lungs, and 

 moderate grade of fever. His nose 

 seemed greatly swollen and he com- 

 plained of a smarting, uneasy feeling 

 in it, and general misery through the 

 head. Gave him treatment to relieve 

 the congestion and fever. Tuesday saw' 

 him again. His nose and face were 

 still more swollen, and in addition to 

 the other symptoms he was becoming 

 slightly delirious and complained a 

 great deal of the intense misery and 

 annoyance in his nose and head. A few 

 hours after, I was sent for in haste with 

 the word that something was in his 

 nose. I found on examination a mass 

 of the larvae of this fly (or "screw- 

 worms" as they are commonly called in 

 the south) completely blocking up one 

 nostril. On touching them they would 

 instantly retreat 01 T)iasse up the nos- 

 tril. Making a 20 per cent solution of 

 chloroform in sweet milk I made a few 

 injections up both nostrils, which im- 

 mediately brought away a large num- 

 ber, so that in a few hours I had taken 

 away some 125 of them. By Wednes- 

 day evening erysipelas had begun, im- 

 plicating the nose and neighboring 

 portions of the face. Another physi- 

 ci;ui was called. By continual syringing 

 with a strcnig antiseptic solution of
