DIPTERA OF MINNESOTA. 



155 



lis, in 1895, reported two cases, possibly this fly, where the ear was 

 the point of attack. The writer was not here at that date, and finds 

 no specimen thus labeled in the collection. 



Three cases of some interest, not occurring in this country, are 

 mentioned here. In one case 250 larvse or maggots were found 

 in the nasal fossae of a sixteen-year-old girl. The second case was 

 that of an old man with an ulcer on his leg, filled with maggots. 

 The third case was that of a three-year-old boy attacked in his left 

 ear. These are only a few of many which are on record. In cases 

 where it is known that eggs have but recently been laid in the nos- 

 trils, if a physician cannot be obtained at once, the nasal passages 

 should be most thoroughly syringed with a solution of one part 

 of carbolic acid to 200 parts of water. 



Methods of Preventing Attacks of the Fly. 



Sores made by barbed wire or otherwise on domestic animals 

 diould be immediately dressed. A solution of one part of carbolic 

 icid in 30 parts of water makes a good dressing; or a mixture of one 

 Dunce of oil of tar in 20 ounces of sweet oil is also recommended. 

 Carcasses of animals dying or killed on the farm should be buried.
