Abstract

In view of the value of the detection of lactic acid in the gastric contents, especially in the diagnosis of gastric carcinoma, the importance of which has been increased by the later work of Boas, and because of the uncertainty and unreliability of Uffelmann's test, I present the following.

The test which I detail is simple and easily applied, the reaction is characteristic, the results reliable. It also affords a method of approximately estimating the quantity of lactic acid present. The test solutions used are:

Solution No. 1, consisting of saturated alcoholic solution gentian violet, 0.2 c.c.; distilled water, 500 c.c.

Solution No. 2, solution ferric chlorid (U. S. P., 1890), 5 c.c.; distilled water. 20 c.c.

The method of applying the test is as follows: Into a small porcelain capsule place 1 c.c. solution No. 1 and add from a pipette 1 drop of solution No. 2. The violet
