BOMBUS TERRESTRIS. 211 



with a very acute pain in the part, very quickly succeeded by an 

 inflammatory swelling, and more or less fever according to the 

 severity of the injury. In general it is sufficient to rub the part 

 with olive-oil, vinegar, or some spirituous embrocation, after 

 extracting the sting. In more severe cases emollient anodyne 

 applications should be resorted to, in order to allay the irritation 

 and swelling, and five or six drops of the volatile alkali administered 

 every fifteen minutes. The same mode of treatment is to be 

 adopted to relieve the pain and inflammation arising from the sting 

 of the common wasp, humble-bee, hive-bee, ichneumon fly, &c.
