wart. The eyelids and the legs are the usual places for warts. 

 Not only is the connective tissue increased to form the bulk of 

 the wart, but the surface epithelium is increased also and they 

 may become malignant. 



An interesting polypus is sometimes found in the vagina of 

 the mare and may grow to a large size. It could be confused 

 with an everted bladder or with an impervious hymen in fillies. 



The condroma or cartilaginous tumor develops commonly 

 on the sternum of the horse or ox, following injury. In the 

 horses we may find one growing in the trachea, following trach- 

 eotomy or from kicks and wounds. If they are limited in size, 

 they can be removed with the knife, but when large, removal 

 is impracticable. In the early stage of their growth they are 

 largely made up of fibrous connective tissue. 



The so-called osteoma or bone tumor is usually an inflam- 

 matory growth and it is not a true tumor. 



The lipoma or fatty tumor consists of fat and it is liable to 

 grow in any animal and in any part. Such a tumor is easily re- 

 moved ; it is non-vascular. Apply a little cocaine when operating. 



The neuroma is a nerve tumor and it is most commonly seen 

 as a sequel of neurotomy. In this operation the nerve should 

 be drawn down and cut off so that the end will draw up into the 

 wound. Then it will not grow out into the granulations which 

 form during the healing of the wound. You will find that when 

 the horse is not benefited by the operation of neurotomy, it is 

 usually due to the formation of one of these tumors. 



CYSTS. 



Cysts are very common and they are important. Examples 

 are Capped Hock, Capped Knee, Wind Galls, etc. They may 

 grow on any part of the body, inside or outside. They may 

 contain hair and they are lined with skin as well as being cov- 

 ered with it. They usually follow an injury. When produced 

 they rapidly fill with serum and an acute inflammation takes 

 place in from 12 to 48 hours. 



Treatinoif. — For cystic tumors on a horse's legs the first 

 thing to do, especially if they are of large size, is to open them.
