DISEASES OP COWS. 459 



This tincture, well infused, is given in doses of three 

 ounces, in two quarts of infusion of savin leaves. 



The removal of the membranes by manual force is 

 recommended when they are wholly or in greater part re- 

 tained, and are causing serious injury. This is done as 

 follows : A person with a small hand and arm, which are 

 well oiled, takes hold of the exposed portion of the 

 membranes with the left hand and follows them into 

 the uterus with the right hand. Feeling cautiously for 

 the attachments, each one is carefully separated until all 

 are loosened, when they come away immediately without 

 any further trouble. In case of partial retention of the 

 membranes one ounce of hyposulphite of soda may be 

 given daily as an antiseptic to prevent harm by the ab- 

 sorption of the retained matter. 



TUMORS OF THE JAW. 



The frequently occurring hard swellings on the jaw are 

 caused by a disease of the jawbone which is contagious, 

 and is produced by a special germ which lives and grows 

 at the expense of the bony substance. It is known as 

 actino mykosis, or ^^ lump-jaw." It is constitutional 

 and descends by heredity. It first appears as a small 

 nodule upon the side of the face or on the jawbone. 

 This grows gradually into a large tumor which dis- 

 charges extremely fetid pus, known by its odor to come 

 from the decaying bone. The progress of the disease is 

 slow but sure. The jaw is gradually eaten away and 

 the animal perishes from inability to eat. The disease, 

 however, is not always fatal, as it has been known to suc- 

 cumb to antiseptic treatment when in its early stages. 

 Some valuable animals, treated by advice of the author 

 with hyposulphite of soda m one-ounce doses daily, 

 continued for three months, have gradually recovered, 

 without any permanent injury or blemish.
