60 A'OKTH CAKOLIXA HOARD OF HEALTH. In connection with the above table it is only fair to say that the showing is, as a whole, very creditable to the State. The average quality of all but a very few of these water supplies is excellent. When the laboratory first began these systematic analyses in 1003, we found that many of the water companies using the mechanical filtering process were running alum into the filtered water. At the present time we rarely find any trace of alum in the filtered waters sent us. The germ contents of all these filtered waters are comparatively low, and the groups represented are, in most cases, harmless, sporiferous saprophytes. The ahuu used as a coagulent in filtering water by the mechanical process has a powerful bactericidal effect. It acts in a destructive way upon these organisms, both mechanically and physiologically. Artesian wells as sources of public water supplies for small towns seem to be growing in favor in this State, and most of the recently established supplies are of this class. All of the artesian waters of this State contain a high percentage of total solids, chiefly the sulphates and chlorides of soda, lime and magnesia. These artesian waters are wholesome, though they are apt to disagree at first with those who have been accustomed to soft, surface water. They are not well suited for steam boilers and other industrial uses. We have advised the managers of the more highly mineralized artesian supplies to install a softening plant, which will remove the larger part of the dissolved minerals—chiefly lime—and thus render the water soft and more desirable for both domestic and industrial uses. In pathological work done for physicians the number of samples of suspected tuberculous sputum sent in is steadily increasing. About three-fourths of all samples of this kind now received show bacillus tuberculosis. In this connection the Biologist desires to say that he keeps himself informed as to the most recent developments in controlling human tuberculosis, as published in German and French scientific periodicals. The consensus of opinion among working European biologists is that tuberculosis is rarely transmitted directly from cows to humans. This does not necessarily mean that there is any radical or specific difference between the germs of human and bovine tuberculosis. It simply means that germs habituated to parasitism on hovines do not easily or at once adapt themselves to the human environment, and as a consequence are less virulent and less able to overcome or counteract the natural protective secretions of the healthy human organism. In other words, most new cases of human tulierculosis seem to arise from some pre-existent human case or infection. The plain moral inculcated by this fact is that such possible infection should be more rigorously guarded against. There should be a stringent law requiring all public assembly and waiting rooms, public carriages, cars, jails, asylums, hotels, etc., to l>e period-
