DISEASES OF THE DIGESTIVE TRACT 99 



After the chicks were hatched they were not to 

 receive any feed for forty-eight to seventy-two 

 hours, as the yolk contained in their abdominal 

 cavity will furnish food for that length of time, 

 and an engorgement of the intestines might im- 

 pinge on this part and interfere with its absorp- 

 tion by pressing on the absorbing vessels. 



The following solution was to be kept before 

 them from the time of hatching to four weeks of 

 age, and then given twice a week for the next few 

 weeks: Zinc sulphocarbolate, fifteen grains, sod- 

 ium and calcium sulphocarbolate, of each seven 

 and one-half grains, bichloride of mercury, six 

 grains, and citric acid, three grains. This quan- 

 tity was dissolved in a gallon of water. The re- 

 sult was that eighty per cent of the next hatch 

 was saved. 



Blastomycosis of the Pigeon 



There is a condition in pigeons in which there 

 is a nodular mass in the upper portion of the 

 esophagus, due to 

 a kind of yeast-like 

 germ. It is termed 

 blastomycosis, and 

 is well illustrated 

 in Fig. 37. The 

 squabs become af- 

 fected early, and as 

 the diseased or tu- 

 mor-like area be- 

 comes larger, the 

 bird is unable to 

 eat or swallow. The
