Diseases of the Digestive System. 203 



passage along the gall-ducts to the intestines, is not 

 uncommon. 



Treatment. — The pain is to be soothed by warm 

 baths and the internal administration of opium, chloric 

 ether, &c., measures which are also beneficial in the 

 removal of the obstruction as well as the resulting 

 jaundice. The presence of one stone suggests the 

 presence and constant formation of many others, therefore, 

 some alteration in the diet should be made, more 

 frequent exercise being enforced, while one of the liver 

 pills {see Aperients), or podophyllin and calomel are 

 regularly given. 



Disease of the Spleen and Pancreas is rarely 

 recognised except in conjunction with morbid conditions 

 of the liver, and chiefly after death. We have, therefore, 

 but little information in reference to morbid signs during 

 life, the principal being enlargement of the spleen, which 

 may be felt on the left side of the front of the belly. 

 The organ is then sensible to pressure, and the animal 

 emits cries of pain when he is moved. A husky cough 

 is present ; the coat is rough and dirty ; the bowels are 

 relaxed, and the evacuations are yellow and mixed with 

 froth, a state which alternates with constipation. The 

 mucous membranes are pale, and fever is more or less 

 present. Emaciation proceeds with the continuance of 

 these signs, and the disease is practically incurable, de- 

 pending on conjointdiseaseof the liver and other organs. 



Goitre, or Bronchocele, is not unfrequent in newly 

 born pups, associated with rickets, the probable result of 

 parental mal-nutrition. Among older animals pugs are 

 singularly liable, the swellings being known as "Kernels." 

 The disease consists of enlargement of the thyroid 

 glands, situate on each side of the throat, which has 

 been known to cause obstruction to the flow of blood in 

 the jugular veins, with resulting dulness, and even death. 

 Pressure on the windpipe has also been known to 

 produce suffocation. The diseased enlargement sometimes 

 disperses spontaneously ; otherwise painting with iodine, 

 after removal of the hair, with internal administration of 

 the drug, will accomplish its disappearance.
