The result points clearly to a state of natural immunity enjoyed by those who, like these men of the Naval Service, lead an hygienic, contented well regulated life with the simple accessories of good and sufficient food, fresh air and regular exercise. The same principle has been recently demonstrated in England in the same connection by the annual report of one of the great public schools celebrated for hygienic methods, where amongst a total of 800 students not a single case of influenza appeared--although no preventive measures were employed beyond the simple rules of health and cleanliness. Finally, as regards serums and specifics, the judgment of Dr. Karl F. Meyer, of the Hooper Institute of Medical Research of the University of California, may be accepted as focusing the consensus of unbiased opinion on the subject. It was as follows: "Serums have not yet been introduced which produce immunity from Spanish Influenza. The serums now employed are of no use whatsoever. You have no idea how really and truly helpless we are. As an example, take the advice given us by the Public Health Department when we asked what should be done if the epidemic struck West. They said: '_Organise your hospitals and undertakers_.'" In the same statement Dr. Meyer declared that the Medical fraternity _is in total darkness as to the cause and nature of the epidemic_. Of other preventive measures resorted to--Masks, Quarantine and the veto upon public gatherings--proved equally mistaken and futile. Masks of a texture calculated to baffle the most determined attempts of the minute invisible homicide were made compulsory, and in the great cities masquerading millions became a constant feature of the streets, until an idea of the danger of masks, _as microbe preservers and carriers_, dawned upon the official mind. Thus, beyond fostering fear and depression amongst the citizens nothing was achieved in the direction desired, but rather the reverse; since it is now very generally recognized that such mental conditions with their consequently lowered vitality are a common prelude to disease. At the annual meeting of the American Public Health Association in Chicago, following a two days' discussion of preventive measures against Influenza and Pneumonia, Dr. Chas. J. Hastings, president of the organization said: "A tremendous amount of damage is done by interfering with nature, when nature would have done better had she been left alone. We have very little power over pneumonia. I am convinced that as many patients have been _killed_ by physicians as have been _cured_." The talented "Health" editor of the Los Angeles Times, commenting upon these matters, writes: "The handling of this epidemic by 'health boards' and doctors who have been running around like wet chickens--their eyes, however, fastened on the feed box--has furnished another striking evidence of the futility of what is misnamed 'Medical Science.'"
