INTRODUCTION  This study of the morphology of the blood with reference to the leukocyte in cases of "irritable heart of soldiers" was suggested by the report of the Medical Research Committee, under the direction of Dr. Thomas Lewis.1 In comparing this work to that which has been published in England, it must be borne in mind that the cases studied in the Hampstead Military Hospital may have differed from the type observed in U. S. Army General Hospital 9, at Lakewood, N. J. However, the basis of this work was a large series of selected cases in which no organic lesion of the heart and no foci of active infection were found by careful and repeated examination. The following are the more common symptoms given by these patients:

  1. Breathlessness, produced by slight exertion.

  2. Precordial pain, coming on suddenly after exertion, spreading over the left chest.

  3. Fatigue, with or without
