Pathologists have long noted that the number of mitotic figures, for example, varies enormously from time to time, as determined by multiple biopsies on the same neoplasm. The rhythms of growth noted in grafted animal tumors are dependent more on the nutritional arrangements between the animal host and the tumor and the rise and fall of tissue immunity, owing to the fact that a graft is to a certain extent, even though growing, a foreign material, so that this observation made by Bashford many years ago is not of great interest. When selected stocks homozygous for the tumor inoculated are employed,
