Experimental Studies On the Ef- fect of Ethyl Gasoline and Its Com- bustion Products-This bulletin of 447 pages including 105 pages of appen- dix is replete with tables, graphs, and il- lustrations to complete the text of the extensive studies made at the Pittsburgh Experiment Station of the U. S. Bureau of Mines extending from December 6, 1923, to August, 1925. Part I concerns the psysiological effect of exhaust gases from engines using ethyl gasoline. Part II, the effects of inhalation of unburned vapors from ethyl gasoline and other motor fuels (gasoline-benzol mixtures, straight benzol vapors and various com- binations of ethyl gasoline with these). Part III, deals with skin absorption ex- periments with ethyl gasoline, 50-50 benzol-gasoline blend, benzol, and benzene (c.p.). In this part are also con- sidered inhalation experiments with ani- mals treated with ethyl gasoline and with other mixtures and chemicals above stat- ed. The following are abstracted from the general summary and findings of in- vestigations which appear on pages 14- 28: Part I.
