ANAPHYLAXIS 51 



cases paralysis of posterior extremities, which may 

 end fatally or complete recovery may result within a 

 few hours. Marked intolerance by some animals to 

 certain drugs, which intolerance was described as 

 being due to idiosyncrasy, has now been found to be 

 drug anaphylaxis ; this intolerance is often seen with 

 iodoform, antipyrin, quinine, and the different 

 bromides. The mallein and tuberculin reactions 

 were thought to be due to anaphylaxis, but Besredka 

 and others seem to have conclusively proved that 

 such is not the case.
