(2) When an intravenous injection of 15 (warmed) pure dis-tilled water was given, there was a marked fall in rectal temperature(Chart 8, Experiment 21). This was accompanied by a constriction ofthe ear vessels and a diminution of respiratory rate and these remainedat their low value even when the rectal temperature had reached itsinitial value again. The same efTect on the ear vessels is seen in Ex-periment 64, in which a fall in rectal temperature was produced by theinjection of -0011 gm. of B. coli communis—Na2S04 powder containing3-8 % dry bacteria.
