PERSISTENT SCIENTIFIC DOUBTS

[Notwithstanding the report of the Cambridge examination of the claims for an economic nutrition advanced by the authors, American physiologists were still doubtful if a nitrogenous economy like that reported could be maintained, and the writer was invited to submit to further tests at the Physiological Laboratory of Yale University, under direction of Professor Russell H. Chittenden, Director of the Sheffield Scientific School, and President of the American Physiological Society, and Dr. Lafayette B. Mendel.

The following article, first published in the Popular Science Monthly, June, 1903, is a report of that test, and indicates a desire to carry the investigation further to include a variety of test-subjects.

In response to Professor Chittenden’s request, the Trustees of the Bache Fund of the National Academy of Sciences appropriated $1000 towards a more extended inquiry; and other means having been assured, a project of experiments was taken under consideration.
