    the guide of our determinations in regards to the preservation and recovery of health. For human temperature varies from this type. Besides its unhealthy variations, perturbations proper, resulting from ex- cesses or sickness, there are ecarts from the norine, like those of the pendulum from its axis; and there are even displace- ments of the axis (norine) by age, climate, occupation, acci- dent, etc., without sickness: anomalies, as normal for a few as the norine for mankind. Let us explain the idea by its very application, and first to II.—The Diurnal Oscillations. Temperature varies a little, oscillates, even in healthy per- sons, aceordingto the time of the day, by .5° C. = .9° F. Lich- tenfels and Frohlich state the time of the lowest from 10 p.m. to 1 a.m., and from 6 to S a.m. ; the highest from 4 to 5 p.m. According to Damrosch the temperature rises from 7 to 10 a.m. about .5°C. = .9° F.; falls till 1 p.m. about .1°—.2° C. = .2°—.4° F. From thence till 5 p.m. it rises .2°—.3° C. = 4°—.0° F. ; and then falls again till 7 p.m. by about .3°—.5° C. = .6°—.9° F. Occasionally the afternoon fall is absent, the 7 to 10 a.m. ele- vation and the 5 to 7 p.m. fall are the most constant. (See Appendix III. a.—Ogle; b.—Alvarenga; c.—Barensprung.) Ogle states an . ec&rt of 1.5° F., Alvarenga excursi from .49° above the norine to .71° below it, total difference 1.20° C., average temperature 36.9° C. Finlayson, of Glasgow, found a daily excursus of 2° 0. as the daily average of 283 observations taken on 18 children. Barensprung (same Appendix, c) notes the excursus above the norme .49°, below .69° C.; total L18°. Like Alvarenga he notes the influence of the meals besides that of the hours. In the following table the same observer shows the tidal movement of daily oscillations : Maximum of the evening (4 to 6 o’cl.) 37.49° Maximum of the morning (9 to 11 o’cl.) 37.20° Minimum of the evening (8 to 10 o’cl.) 37.05° Minimum of the morning (5 to 7 o’cl.) 36.31° Medium of the day (24 hours) 37.03° Labbee indicates two daily maxima irrespective of digestion or sleep, therefore tidal too, and thinks that the sum of the tern-
