KUPTURE CF THE HEART AND LARGE BLOOD VES- 

 SELS. 



Rupture of the heart or large vessels accompanied 

 by fatal hemorrhage appears to be quite common with 

 birds. The cause is over exertion in trying to escape 

 when being chased, or it may be due to compression 

 of small birds in the hands, or to other injuries. It 

 is most common in full blooded or plethoric individuals . 

 Cadeac has noted its occurrence twice with birds af - 

 fected with diphtheria. This accident results' in 

 speedy death, and can neither be foreseen nor treated. 

 Megnin recommends that parrots, on account of being 

 predisposed to this trouble, should constantly be given, 

 for drink, water which has been made alkaline with 

 bicarbonate of soda. t
