in the treatment of subacute and chronic rheumatism, and in 

 that form complicating influenza in horses. 



Potassium iodidje is generally prescribed with colchicum

 rheumatic origin. Colchicum is c.ommonly believed to be 

 a serviceable diuretic in various diseases (although this 

 hypothesis is not physiologically substantiated). It is there- 

 fore recommended in lisemaglobinssmia and swelling of the 

 legs in horses ; in cerebral congestion ; ascites ; pleural and 

 pericardial effusions, and dropsies, as an eliminative. Col- 

 chicine, subcutaneously, is especially lauded in rheumatism.
