Thesame slight changes in the chromatin of the renal epith-elium were found, but appeared less marked. Experiment 5.—White mouse exposed as above andkilled two hours after exposure. No. symptoms. Macro-scopic appearances of kidneys negative. Marked nucleardisintegration in the spleen. Microscopic changes in thekidney the same as in the preceding. Experiment 6.—White mouse exposed as above andkilled two and a half hours after exposure. No symptoms.Macroscopic and microscopic conditions in spleen and kid-neys same as in the preceding. Experiment 7.-—White mouse exposed as above. Nosymptoms. Killed three hours and twenty minutes afterexposure. Spleen red, slightly enlarged. No macroscopicchanges in kidneys.

Killed four hours after exposure. Spleenslightly enlarged. No macroscopic changes in kidneys.Microscopic picture same as in preceding, with slightlymore disintegration in the spleen. Experiment 9.—White mouse exposed as above. Fourhours after exposure the animal was more quiet than nor-mal and its eye-sight was apparently impaired. Backhumped. It was killed five hours after exposure. Thespleen was somewhat swollen and brownish in color. Nomacroscopic changes in the kidneys. Microscopic examina-tion showed slight cloudy swelling of the renal epithelium. Experiment 10.—White mouse exposed as above.Several hours after exposure became quiet, back humped,eye-sight impaired. Was killed six hours after the ex-posure. The macroscopic and microscopic pictures same asin the preceding. Experiment II
