JAUNDICE OR YELLOWS. 85

 introducing a less virulent form of the disease amongst 

 them, he seldom or never knew them to sicken after-

 even when they might experience a second attack.

 the excretory ducts of the liver, it either regurgitates 

 into the habit of the hepatic veins, or is absorbed by 

 the lymphatic system, in either case it produces the 

 disease called jaundice." This is frequently generated 

 by too high feeding, without a sufficient quantity of 

 exercise ; lying in damp places will also produce it ; it 

 is exceedingly dangerous, when it attacks puppies 

 which are also suffering from distemper, and it almost 

 invariably proves fatal, at least I never knew an instance

 with hepatic absorption, in distemper and acute inflam- 

 mation of the abdominal viscera, but that icteric 

 obstruction to the flow of bile producing human 

 jaundice I have not met with in them." The method 

 which I have always pursued has generally proved
