limited degree. Smoke is a protection against them, and it is produced 

 by putting live coals into heaps of dung, leaves, hay, and the like. 

 Another protection against their bites is an embrocation of tobacco decoc- 

 tion or of kerosine oil. For cattle, an ointment is made in the following 

 way : 2 lbs. of tobacco leaves are boiled in 20 lbs. of water, the decoction 

 is evaporated to the consistency of honey, then to this extract is added 

 1 ib. of lard and J oz. of kerosine oil. The resulting ointment is 

 rubbed into the skin of the cattle and has the effect of keeping the 

 flies off. It has to be applied especially near the openings of the body, 

 on the belly and genitals, and the application must be repeated every 

 third day. 



Against the bites of the flies and their consequences on the recom- 

 mendation of Schonbauer people apply fomentations of lukewarm milk, 

 warm poultices of linseed and water, fresh linseed oil, or fresh butter, 

 which diminish the smarting pains very much and prevent swelling, if 

 they are used early enough. Finally, lukewarm softening baths are re- 

 commended ; also internally cooling drinks, and in convulsions opiates. 



Besides this, washing with diluted Goulard-water, vinegar and 

 ammonia is recommended. Aqua plumbic, grm. 400, externally.

2. Description of a new species of the Dipterous Genus Simulium 

 from Assam. — By Dr. Edward Becher. Communicated by J. Wood- 

 Mason. 



(Abstract.) 



This paper consists of a detailed description of the insect, which 

 Dr. Becher has named Simulium Indicum, and is illustrated by a plate. 

 Dr. Becher remarks that this is the first known Asiatic species. Only 

 a few of the non-European species have hitherto been described, whilst 

 the number of the European species is not inconsiderable.
