it, and die off quickly and in large numbers. It is 

 a very peculiar disease and the same as in many others 

 the hirds' health must be in a certian condition to al- 

 low the germ to develop and the disease to take prop- 

 er hold, although it is very often inherited from the 

 parents and may run back for generations. Birds ap- 

 parently well may have Roup in a mild form and may 

 not suffer much, but their offspring never thrive and 

 generally die before a month or two of age. 



The germ or bacillus is the same in all cases but 

 the severity of the symptons altogether depends upon 

 the condition upon which it was developed, i. e. deli- 

 cate birds and ones which catch cold very easily are 

 liable to contract it much sooner than stronger birds 

 although the latter when afHicted often die off quicker 

 than the former. Roup affects birds as well as poultry 

 in most all climates and countries the bacillus tuber- 

 cles being found wherever birds live. The germs after 

 taken into the system gradually develop, becoming 

 increased in numbers to such an extent that the bird 

 finally dies from true form of Tuberculosis. 



Symptoms: High fever, offensive breath. The 

 breathing is somewhat constricted caused by the thick- 

 ening of secretions of the mucous membranes, there is 

 some sneezing and cough. From the nostrils there 

 comes an offensive discharge, bubbles appearing in the 

 mouth and sometimes at the corner of the eyes. The 

 membranes of the mouth have a very pale appearance 

 probably due to a deposit of tubercules being formed 

 after which ulcers put in their appearance. It may 

 however be only a sign of anaemia or deficiency of 

 the red corpuscles of the blood caused by the di- 

 sease.
