horse. They may reach a great length and appear as a horn. Dr. Glass saw one 
from the back of a cat. 
Papilloma, or warts, are common in animals as well as man, usually hard, but 
soft when occurring in mucous surfaces. A wonderful display of these tumors 
was presented in the oral cavity of a dog. 
Admoma usually occurs in the mammary gland aud other vacimos glands. 
Several specimens from the -mammae of bitches were then shown. To distinguish 
admoma from cancer, in the former the skin is freely movable, while in the latter 
it ulcerates. 
Under the head of cysts there was a retention cyst of a mule containing seba- 
cious material. Dr. Huidekoper spoke of the so-called “shoe-evil ” as an instance 
of cystic degeneration. 
The ovarian cysts of a cow were then exhibited and Dr. Formad said they 
were fibrid with cystic changes. There was one presented from ovary in bitch 
and also a cystic sarcoma of intestion and one of ovary in mare, and a dumoid 
cyst of a fowl filled at one time with feathers, also several others of like interest. 
Dr. Formad showed foetal bones found in the fallopian tubes of a mare, 
showing a remarkable instance of extra uterine pregnancy. 
Dr.Zuill mentioned a well authenticated case of a foetus found in the abdom¬ 
inal cavity of an ox. He also mentioned a case of hypospaduis thought to be a 
case of hermapheoditicism. 
As the evening was far spent Dr. Huidekoper moved that Dr. Formad 
should continue next month, which was seconded and unanimously carried. 
The meeting then adjourned. 
At a regular monthly meeting of the Keystone Veterinary Medical Associa¬ 
tion which was held on March 3, 1888, at the Veterinary Department of the Uni¬ 
versity of Pennsylvania, Dr. Zuill presided, the minutes of previous meeting were 
read and roll called, to which eleven members responded. 
. Dr. Formad resumed his lecture on Tumors, starting with actinomycocis, 
which is a disease affecting bone, and he considers it a disease closely allied to 
tuberculosis (Pearl Disease). It is of parasitic origin, otherwise it has the structure 
of sarcoma and he suggests the name of actinomycoma. There are one or more 
fine specimens of thi3 disease. 
The sarcomata are well represented in animals and many fine specimens were 
presented from the museum. The most common under this head are the melan¬ 
otic sarcoma, but not cancer. It is most common in grey or light colored horses. 
In man it generally starts in the eye and gives metastasis. It sometimes starts 
in the skin. It never gives metastasis to the skin but always to an internal organ. 
It proliferates to a large extent and produces enormous metastatic tumors. 
Every black tumor (excepting those caused by accidental hsemorrhage) are 
melanotic. Numerous specimens were then exhibited. 
Dr. Hoskins mentioned a remarkable case that was situated in rectum of a 
horse which subsequently broke down, discharged contents and animal recovered. 
Melanotic tumors in horse are often situated in skin and especially about the natural 
openings. Prof. Zuill mentioned case where he thought the tumors nearly equalled 
the body weight of the patient. Numerous interesting cases were reported by sev¬ 
eral of the members. 
Sarcomas are divided into two classes, the benign and malignant. The benign
