 rise to the disease and death of cattle suspected of loco-poison- 

 ing. In cattle that died he found enormous numbers of sarco- 

 sporidia. They were very numerous in the heart and muscles. 

 He 4 reported that his work in and about Lethbridge showed

that sarcosporidiosis may be closely associated with and is 

 probably a very frequent sequel to the disease of cattle known 

 as loco- disease. He feels that this form of parasitism may 

 complicate the diagnosis in both loco-poisoning and dourine. 

 Foelger 5 calls attention to the presence of eosinophiles in the 

 muscles infested with sarcosporidia.
