passage along the gall-ducts to the intestines, is not 
uncommon. 
TLveatment.—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 conjoint disease of 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.
