The method here proposed for making the typhoid agglutination test requires an ordinary microscope slide, or other piece of glass, a surgical needle or other puncture needle, and an ordinary medicine dropper, all costing less than 10 cents. The material required is one drop of a suspension of typhoid bacilli that should not cost more than half a cent for each test made. The time required to make the test is less than two minutes. No special bacteriological or laboratory experience is necessary; and the test, when properly performed by one with even limited experience, is as reliable and accurate as can be made by an expert bacteriologist within an hour with a microscope and the facilities of a laboratory. The test may be made at the bedside in two minutes instead of waiting hours for a report from the laboratory or a day or two as country
