coustitutional disorder therefore, we must look rather to the de-. 

 rangements of the digestive functions, to the abnormal condition 

 of the faeces, and to the alterations in subordinate functions like 

 the glycogenic action of the liver, for indications of an unhealthy 

 state of the pancreas. The suppression of the pancreatic secre- 

 tion has long been associated with the occurrence of fat in the 

 stools, yet this may result from the lack of bile which has im- 

 portant functions to fulfill in emulsionizing fat, and in securing 

 its endosmosis. On the other hand the lack of pancreatic juice 

 may hinder the complete digestion of the albuminoids, and favor 

 their fermentation and the occurrence of tympanies, congestions, 

 abnormal secretions, etc. , which may be easily attributed to an- 

 other origin. Then again the dependence of the liver on the 

 pancreas for its stimulus to glycogen e.sis, would suggest a series 

 of disturbances from the abundance of the unused food principles, 

 from the hindrance to nutrition and growth, and perhaps from 

 the toxic action of the hepatic products. Once more, through 

 the common excretory duct, infection of the pancreas may extend 

 to and involve the liver, and blocking of the common duct by 

 pancreatic parasites, or calculi, may .stop the flow of bile and 

 cause jaundice or other icteric disorder. And yet, it is rarely the 

 case that pancreatic disorder is succe.s.sfully diagnosed, and it is 

 too often only at the post mortem examination that the actual 

 lesions are revealed. 



CATARRHAL PANCREATITIS. 



Probable causation by parasites, calculi, irritants, microbes. Lesions : 

 mucosa reddened, thickened, ducts dilated, epithelium fatty, granular, des- 

 quamating, pus, connective tisstie indvirated. Interdependence of pancre- 

 atitis and hepatitis in horse, sheep and goat. Liver lesions. Symptoms : 

 loss of vigor, endurance, appetite, and condition. Icterus, costiveness, 

 foetid, fatty stools, percussion tenderness — right side. Treatment : anti- 

 thermics, eliminants, antiseptics, derivatives, alkalies, salicylates, ether. 



Causes. We know little of the causes of this affection, but it 

 may be inferred that parasites, calculi and other irritants, will 

 produce in this as in other mucosae a mucopurulent inflammation. 

 Then again the presence of pus suggests the cooperation of pus
