306 INORGANIC AGENTS 



In acute diseases, as pueumonia, these antipyretics may be 

 occasionally employed to advantage when the temperature 

 rises above 104^ Far., and remains there any length of time. 

 They are generally inadvisable in asthenic, febrile diseases, 

 since they are too depressant in their action upon the heart 

 and have no effect in removing the cause of the disease. 

 The hyperpyrexia of insolation may be treated with these 

 agents, in combination with cold, externally and per rectum. 

 For the relief of pain their scope is limited in veterinary 

 practice to that of a rheumatic character. Motor distur- 

 bances, including convulsions, chorea and spasm, may be 

 abated by the antipyretics, but they are usually inferior to 

 chloral, opium, or other antispasmodics. 



Phenacetin, combined with codeine or heroin, in powder 

 or tablet, is a useful remedy for cough in dogs.
