Hospital, Mok Po city. The results obtained were as follows ; 1. The thermometer sterilized with 0.1 ％ bichloride of mercury sponge showed no growth of bacteria organism in 5 cases but showed growth of pathogenic organism in 1 case and non pathogenic organism in 4 cases. 2. The thermomerer sterilized with 70 ％ alcohol sponge showed no growth of bacteria organism in 8 cases but showed growth of nonpathogenic organism in 2 cases. 3.
