"In those places where infectious diseases, according to experience, are prevalent and unusually severe and frequent, it is necessary to abstain as much as possible from the employment of water taken from without the ship for cleansing said vessel, and also for washing out the hold when the water of the sea or of a river, in the judgment of the commander of a vessel, confirmed by the statement of the physician, is shown to be surcharged with organic matter liable to putrefaction. With this end in view, if you are unable to send elsewhere for suitable water, you must make use of good and fresh water, but with the greatest economy. In that event the purification of the hold must be accomplished by mechanical means or by disinfectants." "As I have demonstrated by my investigations that in the distillation of paludal water, and that from the marshy shores of the sea, the Limnophysalis hyalina, which is impalpable, is carried away and may be detected again after the distillation, it must be insisted that the water intended to be used for drinking on shipboard shall be carefully filtered before and after its distillation." The Klebs-Tommasi and Dr. Sternberg's report, as summarized in the Supplement No. 14, National Board of Health Bulletin, Washington, D.C., July 18, I would cordially recommend to all students of this subject. I welcome these observers into the field. Nothing but good can come from such careful and accurate observations into the cause of disease. For myself I am ready to say that it may be that the Roman gentlemen have bit on the cause of the Roman fever, which is of such a pernicious type. I do not see how I can judge, as I never investigated the Roman fever; still, while giving them all due credit, and treating them with respect, in order to put myself right I may say that I have long ago ceased to regard all the bacilli, micrococci, and bacteria, etc., as ultimate forms of animal or vegetable life. I look upon them as simply the embryos of mature forms, which are capable of propagating themselves in this embryonal state. I have observed these forms in many diseased conditions; many of them in one disease are nothing but the vinegar yeast developing, away from the air, in the blood where the full development of the plant is not apt to be found. In diphtheria I developed the bacteria to the full form--the Mucor malignans. So in the study of ague, for the vegetation which seems to me to be connected with ague, I look to the fully developed sporangias as the true plant. Again, I think that crucial experiments should be made on man for his diseases as far as it is possible. Rabbits, on which the experiments were made, for example, are of a different organization and food than man, and bear tests differently. While there are so many human beings subject to ague, it seems to me they should be the subjects on whom the crucial tests are to be made, as I did in my labors.
