believe, than any city in the United States. It has been brought about in great part by researches into the life history of the parasite which produces malaria, and by the effectual measures taken for its destruction. Here again is a chapter in human achievement for which it would be hard to find a parallel. But let us not forget that these are but illustrations of wide-spread possibilities of organization on modern lines. These are sanitary blessings. To make them available in the Tropics is the heaviest burden of the white man; how heavy you may know from the startling figures which have just been issued from British India. Exclusive of the native states for the year 1908, the total deaths from fever and cholera exceeded 5,000,000, out of a population of 226,000,000. The bright spot in the picture is the diminution of the mortality from plague--not fewer than a million fatal cases as compared with 1907. These are brief indications of the lines along which effective progress is being made in man's redemption by man. And all this has a direct bearing upon the disease, the fight against which brings us together. Tuberculosis is one of the great infections of the world, and it has been one of the triumphs of our generation to determine its cause. With the improvement of sanitation there has been a reduction in its mortality, amounting since 1850 to above 40 per cent. But it still remains the most formidable single foe, killing a larger number of people than any other disease--some 60,000 in Great Britain and Ireland in 1908, and 589 of this city. Practically between 10 and 11 per cent. of all deaths are due to it. A plain proposition is before the people. We know the disease--how it is caused, how it is spread, how it should be prevented, how in suitable cases it may be cured. How to make this knowledge effective is the prime reason of this conference. It is a campaign for the public; past history shows that it is a campaign of hope. The measures for its stamping out, though simple on paper, present difficulties interwoven with the very fabric of society, but they are not insuperable, and are gradually disappearing. It is for this reason we urge you to join with enthusiasm in the crusade; remembering, however, that only the prolonged and united efforts, carried through several generations, can place the disease in the same category with typhus fever, typhoid and small-pox.
