ing mites that may have escaped the brushing the meat 

 may be dipped for half a minute in a solution of one part 

 of carbolic acid, ten parts of alcohol, and ninety parts of 

 water. This solution should kill the eggs and mites and 

 not injure the meat. 



A storeroom or pantry once infested should be thoroughly 

 cleaned and then may be fumigated with sulfur at the 

 rate of 2 pounds to 1000 cubic feet or with hydro- 

 cyanic acid gas at the rate 

 of 1 ounce to 100 cubic 

 feet. If the room is not 

 fumigated, it may be 

 thoroughly sprayed or 

 washed with kerosene oil. 

 The oil should be forced 

 into all of the cracks and 

 crevices where the mites 

 may be in hiding. Prob-

Remarks on the species. Banks, from the material 

 that he had at hand from the United States, found two 

 species of the genus Glyciphagus. In this genus, the 

 cuticle is more or less granular and the hairs of body 

 plumose or scale-like. The name of the genus indicates 

 that these mites are the true sugar mites and cause the 

 disease of which we have spoken as "grocer's itch." We 

 figure one species G. robustus after Banks (Fig. 94).
