The study of animal tumors has assumed great importance in recent years owing to the demonstration of the transmissibility of the malignant neoplasms occurring spontaneously in albino mice and rats. Of late, the discovery of a peculiar sarcoma of the fowl has interested investigators on tumors because this growth is transmissible by cell-free filtrates. This property has been used as a basis for far reaching but as yet unsubstantiated theories concerning the possibility of a parasitic origin of human growths. However, this property of filtrability seems to be wholly confined to tumors of the fowl. Interesting tumors in guinea-pigs and rabbits are also being studied. Such investigation has led to renewed interest in the morphologic examination of the great variety of neoplasms frequently found in other domesticated animals, and it is now clear that practically all the tumors that occur in human beings may be found in animals.
