Excerpt from Studies From the Otho S. A. Sprague Memorial Institute, Vol. 5: Collected Reprints Wild animals in general would seem, as far as the very small number of recorded cases indicates, to have a relatively high incidence Of sarcoma as contrasted with carcinoma. Of 34 tumors found in all sorts of animals in the Philadelphia Zoologi cal Gardens by F ox there were 18 epithelial tumors and 10 sarcomas. Of these 10 sarcomas, 4 were in birds, and, especially since Rous's studies, the relative frequency of connective tissue growths in birds is generally recognized. But even with the birds eliminated, the relative incidence of sarcoma is high in the wild animals. Of the 6 mammalian sarcomas in Fox's collection, 3 were in wolves, 1 in a male wild mouse (peromyscus leucopus), 1 in a Dorcas goat and 1 in a zebra. The mouse sarcoma was spindle-cell, arising from the soft tissues of the right thigh, and metastases are not mentioned.
