or three days another a little tighter for a day and then cut off 

 and sear with a hot iron. Considerable inflammation is apt to 

 accompany this method, but it is the best way. 



The ovarian cyst is common in women, cows and cats. It is 

 a dropsical condition of the ovary and it does not always involve 

 the whole of the organ. In the human these cysts may become 

 malignant by the growth of the epithelium lining the cavity. 



Sometimes these cysts can be treated heroically by inserting 

 the hand in the vagina and another hand in the anus and crush- 

 ing the cyst between the two. The serum escapes into the ab- 

 dominal cavity and does no harm. Give soft feed and rest and 

 the animal will recover in a day or two. 



Mucous cysts develop in the mucous membrane and fill with 

 mucus instead of serum. In the mouth they are called Ranula, 

 and they grow into long, tuberous forms. Slit them up full 

 length and wash out with boracic acid solution. 



Cysts in the thyroid gland are called bronchocele when they 

 are filled with water, and goitre when they fill with the solid 

 colloid substance. Goitre is very common in dogs and they fre- 

 quently develop into malignant growths of the sarcomatous type. 



Treatment. — In new growths, paint the parts with iodine once 

 a day and give iodide of potash internally. If the skin gets 

 sore, cease the treatment for a time and then continue again. It 

 is a dangerous operation to attempt to dissect such a tumor out. 

 It is, however, an operation that is becoming more common 

 every day, especially in the human. Goitre is also very common 

 in the stallion. Thyroid extract is used in the treatment of goi- 

 ters in dogs with much success. 



Dentigeroiis or teeth-bearing cysts are often found. Tumor 

 teeth may be found most anywhere, but frequently at the base 

 of the ear. sometimes in the maxillary sinuses or the frontal and 

 also in the testicles or ovaries. When they develop at the base 

 of the ear, there will first be seen a little swelling, which will 

 grow suddenly and finally rupture. Upon cutting it through a 

 molar tooth may be found which seems to grow without a matrix. 



Certain inflammations may result in hard fibrous swellings 

 which become more or less permanent. The so-called scirrhous 

 cord is one example. It is not a true tumor, but is the result of
