In the dog variation in the temperature of the blood, before it is withdrawn from the artery, between the limits of 25° C. and 45·1° C., does not appear to affect its coagulation time provided it is kept at a constant (25° C.) temperature afterwards. Prolonged etherisation does not affect the coagulation time appreciably. Changes in the temperature of the blood, after it is withdrawn from the body, produce a marked affect on its coagulation time. From 10° C. to about 40° C. the time is shortened as the temperature rises, and beyond this from 40° C. upwards, it is lengthened. At 55° C. or 56° C. the blood does not coagulate at all.
