    GASTRIC STIMULATION. It was decided that the best results would be obtained by following the Fractional Testmeal Method, as described by Rehfuss. This method is described in all the text-books, and it is too well- known to be repeated here. It is sufficient to say that the gastric contents are withdrawn every 15 minutes after giving the testmeal, and the specimens so obtained are analysed for their various constituents. In the first part of the investigation, human gastric juice, which was produced by the ingestion of Brand’s Essence, was analysed, and the free and total acidity tested. As a standard of comparison a similar investigation was made upon a number of persons, using one pint of gruel as a testmeal. The curves illustrate quite lucidly the points of dissimi- larity in the two cases. ae RE she tb Ee ae ee ee ee 60 60 HH 1 = 4 r] 50 50 40 40 alyact 50 30 total 20 acid me : freq ac 10 = -Jol t free] aci 30 wecw =?
