In studies of the coccidium and tlagellato in artificial culture alkaline media 

 furnished a condition favorable to rapid development, while acid media re- 

 stricted development. Milk soured by means of inoculation with pure cultures 

 of a strongly acid producing micro-organism {liacUriuin huloaricum) was fed 

 in large amounts. It is relished by the poults and uj* to the time of writing has 

 shown a marked tendency to prevent manifestation of the severe clinical symp- 

 toms and pathological appearances of the disease, ;it least during the early 

 critical period (thirty-fifth to fiftieth day).
