For many years Dr. Mulligan and some of his veterinary colleagues have collected spontaneous tumors occurring in dogs. This well written book is a description of 1,000 tumors so observed. Approximately one-half the tumors were malignant, and these were about equally divided between carcinomas and sarcomas. Carcinoma was most frequently found in the mammary glands and skin. Curiously, the most frequent type of sarcoma was that involving mast cells. A good bibliography and a technical supplement are included. The photomicrographs are of excellent quality and are generously provided.
This is one of those small monographs that arises from years of personal work in some specialized field providing useful knowledge that could not have been attained in any other way.
