. Fever, thermotaxis, and calorimetry of malarial fever. 2 ISAAC OTT. expect to use one so graduated that I can read fiftieths. The rectaltemperature would have been preferable on account of bucket, I, receives the water from the motor, X, and so con-veys it to the water-wheel, N, that it runs the meter as an meter is filled with water, and belongs to Voits little respira-tion apparatus. The quantity of air aspirated an hour is five tosix thousand litres, which is sufficient for respiratory purposes. Theinstrument is made air-tight by means of the door, K, which isclamped by eight powerful iron clamps. The inner edge of the dooris lined with rubber. The whole apparatus is enclosed in over sixinches of saw-dust, the door, K, having against it a saw-dust mat-tress. The interior of the instrument is lighted by an electric lightof one-candle power, by which a paper can be With these arrangements, excepting light, and a mattress insidethe instrument I have tested the apparatus. As the apparatus ne-cessary for the hydrogen test was not available, I used absolutealcohol. The different physicists who have burned a gramme ofalcohol have obtained the following various numbers : Thus Rum-ford obtained 6,195 ; DuLong, 6,962 ; Andrews, 6,850; and Favreand Silbermann, 7, These numbers mean so many gramme-calories, and the number 7,183, is supposed to be the most accu-rate. In their experiments, in order to allow for the loss of heatdue to radiation, a preliminary experiment was made with the bodywhose heat was sought, the only object of which was to ascertainapproximately the increase of temperature of the cooling water. Ifthis increase be io°, for example, the temperature of the watercalorimeter was reduced one-half this number—that is to say, 50below the temperature of the atmosphere. By this method the CALORIMETRY OF MALARIAL FEVER. 3 water of the ca
