growth when transplanted into other mice; but after the animal bearing the tumor had been irradiated for twenty minutes there was noticed a slowing in the growth rate of the tumor after inoculation, which gradually increased until after sixty minutes there was no growth at all (Fig. 7).When carcinoma 11 was exposed in vivo and then transplanted into other mice, it was found that slightly longer exposures to roentgen ray than in the case of sarcoma were required before any effect was shown on the growth of the tumors after inoculation.After sixty-five minutes' exposure the appearance of the tumor was delayed, but showed fair growth ; and it was not until after an exposure of seventy minutes that no growth resulted (Fig. 8).CONCLUSIONS
