On the Blood-Picture (especially Blood-Platelets and reticulated red Cells) and Blood Sedimentation of an ankylostomiasic Patient

1. In the cases of ten healthy men, the number of blood-platelets amounted to 260,000 at the smallest and to 300,000 at the largest as it was determined by Fonios method. 2. The number of blood-platelets in the ankylostomiasic case is equal to the upper limit of the number of blood-platelets of a healthy man or even exceeds it. It amounts to an average of three hundred and sixty-one thousand, not running parallel with the intensity of anemia, and seems to return to its normal value before the convalescence of anemia which follows the extermination of worms. 3. Corcerning the other blood-pictures, hemoglobin and red blood corpuscles, nothing noteworthy was found within the field of prede-cessors' works, and the reticulated red cells were normal or increased slightly in number. 4. The velocity of blood sedimentation increases, generally coinciding with the intensity of anemia. At the conclusion. I wish to express my cordial thanks to Prof. K. Kukinuma, for his unfaubiling guidbauce aud revision of my results.
