    [Reprinted from the THERAPEUTIC GAZETTE, November, 1909. ] A SECOND SEASON’S EXPERIENCE OF HYPERTONIC TRANSFUSIONS IN CHOLERA CONTROLLED BY OBSER- VATIONS ON THE BLOOD CHANGES. BY LEONARD ROGERS, M.D., F.R.C.P., Be.4 PR.CS. The great majority of cholera patients are admitted in the collapse stage of the disease or very soon pass into it. This is obviously mainly due to the great loss of fluid from the body by the copious vomiting and watery stools, the latter often amount- ing to several pints at a time. As, however, Dr. George Johnson, in his advocacy of the evacuant treatment of cholera, as late as 1866, denied that there is any relationship between the loss of fluid and the death-rate of the disease, I have investigated the blood changes from this point of view. The results were published in the Proceedings of the Royal Society early this year, so need only be summarized here. In a severe case of cholera the great concentration of the blood is at once apparent on opening a vein, while a blood count shows seven to eight million red corpuscles per cubic milli- meter. The specific gravity is raised from 1056 to 1065 to 1075. In order to obtain @ more accurate measure of. the loss of
