By the study of one or more of the recommended text-books 

 on diseases, every poultryman and student may become familiar

 treated by the following method if the value of the bird warrants 

 the time and trouble : 



Wash the hands and instruments thoroughly with soap, then 

 rinse the hands in a 1 to 1,000 solution of bichloride of mercury.
