For examining the blood group and precipitin reaction of the dried blood or saliva stain, the author used the heat and mechanical actions under ultrasonic radiation. The results are briefly as follows: It was apparent that the determinations of blood type and precipitin reaction were rapidly completed by ultrasonic radiation (710 kc) of intensity of 1000 V (radiation time-over 10 minutes) or 1500 V (radiation time-over 5 minutes) against the dried blood stain and 1000 V or 1500 V (radiation time-both over 5 minutes) against the dried saliva stain.
