DR. IVAN A. MITROPOLSKY, of Moscow, warmly recommends, on the ground of his personal experience, the following simple method for preventing or aborting all symptoms of seasickness. As soon as giddiness, nausea, etc., appear, the author shuts his eyes and begins to make deep and slow inspirations and expirations. In a few moments (sometimes after three or four respiratory cycles) the symptoms disappear, to yield to a comfortable subjective sensation. On their reappearance the same procedure is repeated again and again. If the recurrence be rather frequent, it is better to perform the procedure in a recumbent posture (with closed eyes). Since the time the author has begun to practice the method, he never yet suffered from vomiting on board. In referring to this case in the London Medical Recorder, Dr. Idelson says that Dr. Mitropolsky seems to think that the means proposed by him are novel. Meanwhile, in the British Medical Journal, March 24, 1888, p. 676, he will find a very interesting note by Dr. J. J. Leiser, in which the writer says: (1) That seasickness is caused by irregular and imperfect respiration, leading, necessarily, to an inadequate aeration of the patient's blood, which consequently becomes poisonous to his brain and gives rise to sympathetic sickness; (2) that a system of regular free breathing prevents sickness or rapidly relieves it; and (3) that his experiments were successfully repeated by Drs. G. C. Stockman and C. W. C. Prentice, who, having selected ten suffering passengers, each seated himself with five of them and "timed the breathing in the following manner: They [the doctors] raised the hand from the knee, indicating an inspiration, and down again for an expiration, thus timing the respirations to exactly twenty per minute. At the expiration of one hour, the active symptoms in each case had entirely subsided." By this time the doctors had thoroughly educated their patients in the modus operandi of the cure. The cases continued to be permanent "cures" during the remainder of the voyage from Queenstown to the United States. The writers conclude by asserting that "the cure is infallible in all cases that persist in carrying it out."—Medical Record.
