By the study of one or more of the recommended text-books 
on diseases, every poultryman and student may become familiar 
with the symptoms, causes, and common methods of treatment 
of the diseases outlined. These are by no means all of the diseases 
of poultry, but they cover the more common affections. 
Poultry Surgery.—In the case of lacerations, cuts, or other 
wounds, a little knowledge of surgical methods may enable one 
successfully to cleanse and sew them up, thus in many cases saving 
a valuable bird. From a surgical standpoint, there is more lati- 
tude with poultry than with almost any other animals, as illus- 
trated in the operation of caponizing. This is usually performed 
with but little, if any, attention to aseptic precautions. 
Cuts or wounds of any degree of severity may be successfully 
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. 
Pluck all feathers in the vicinity of the wound and wash the 
adjoining parts with warm water, using a piece of cotton or soft 
cloth, then wash with the mercury solution. 
If the wound is small, it need not be sewed up; if large, it 
should be sewed with white silk thread previously soaked in alcohol. 
If the wound penetrates the muscles or other organs besides the 
skin, sew each up separately. 
When completed, powder the wound with iodoform, put the 
bird in a small, clean coop, and watch the wound for a few days 
and keep it clean. 
Bumble Foot.—This means corns or abscesses on the sole of
