Abstract
CATTLE bloods were examined at intervals during the course of the day at Kabete, Kenya, altitude 6,300 ft., the maximum temperature at the season of the experiment being greater than 75° F., the minimum less than 52° F. The cattle were Zebu/European cross. Water was given them at one point while the experiments were in progress but did not affect the results. Blood was drawn from the jugular vein into oxalated tubes, prepared according to Wintrobe1. The neck was constricted with a rope while the vein was entered, but released while the blood sample was being drawn. Blood was drawn at hourly intervals between 9.0 a.m. and 3.0 p.m.
