820 PARASITIC DISEASES. 



The vitality of the trichinae is not destroyed unless the meat 

 in which they are contained is exposed to the influence of the 

 heat of boiling water for a sufficient time to insure that every 

 particle of it has been acted upon by that degree of heat. The 

 mere toasting of ham or bacon is insufficient to destroy the 

 worms, and smoked ham and German sausages are, unless well 

 cooked, sources of danger. Many remedies have been suggested 

 for the destruction of the trichince in the treatment of the 

 disease, more particularly picric acid, picro-nitrate of potash and 

 benzole, carbolic acid, sulpho-carbolate of soda, &c., but none of 

 these have been proved to have any effect ; indeed, in trichinous 

 pork of a pig killed with picric acid, the worms were found 

 alive by W. Miiller of Homburg.
