Last year I described two cases of leukemia treated with benzol (benzene, C6H6) after the plan of Koranyi. This article1 is so recent that it will not be reviewed here. The extensive bibliography on the subject is also omitted; it was reviewed then, and Sappington and Pearson2 have given a list of the articles on the subject to the date of their own.
Suffice it to say now that the patient with lymphatic leukemia referred to has since died. As suggested, benzol was discontinued shortly after the paper was printed because it seemed to have no effect on the leukemic process. So far as we could see, benzol neither helped nor harmed the patient.
The second case, one of the splenomyelogenous type, has been under observation almost continuously since Aug. 23, 1913, nineteen months. The length of treatment exceeds any that I have seen recorded,
