The temperature of the blood varies slightly in different parts of the circulation. Its average heat near the surface is in health about the same, viz. 98-1/2 degrees F. Blood is alkaline, but outside of the body it soon becomes neutral, then acid. The chloride of sodium, or common salt, which the blood contains, gives it a salty taste.
Slept eight hours last night, and came to the city on the 7.45 A. M. train. At 8.25 weighed 189 pounds. 4 P. M., was examined by Dr. F. B. Carpenter, who found the temperature 98-1/2° F., pulse regular, tongue clean. Measurements were: waist, 41 inches; chest, 41 inches; hip, 45 inches; calf, 16 inches; biceps, 13-1/2 inches; forearm, 11-1/2 inches. 5.15 P. M., weighed 188 pounds.
The temperature of the frog may be 85 degrees F. in June and 41 degrees F. in January. The structure of its tissues is unaltered and their vitality unimpaired by such violent fluctuations. But in man it is necessary not only for health, but even for life, that the temperature should vary only within narrow limits around the mean of 98-1/2 degrees F.
Read it while in position or the instant it is removed. The natural temperature of the mouth is about 98-1/2 degrees F. Experiment 117. To show the vocal cords. Get a pig's windpipe in perfect order, from the butcher, to show the vocal cords. Once secured, it can be kept for an indefinite time in glycerine and water or dilute alcohol. Experiment 118. To show that the air we expire is warm.
The continual chemical changes, then, chiefly by oxidation of combustible materials in the tissues, produce an amount of heat which is efficient to maintain the temperature of the living body at about 98-1/2 degrees F. This process of oxidation provides not only for the heat of the body, but also for the energy required to carry on the muscular work of the animal organism.
The chief use of clothing, from a hygienic point of view, is to assist in keeping the body at a uniform temperature. It also serves for protection against injury, and for personal adornment. The heat of the body, as we have learned, is normally about 98-1/2 degrees F. This varies but slightly in health. A rise of temperature of more than one degree is a symptom of disturbance.
But these two great obelisks of Queen Hatshepsut were 98-1/2 feet high, and weighed about 350 tons apiece. Yet Sen-mut had them quarried, and set up, and carved all over from base to summit in seven months from the time when the Queen gave her command!
The bonds were delivered to the creditors at the rate of 98-1/2 per cent of their face value.
We have the names in one of the tables arranged in two columns, representing, as you see, two groups platinum, iridium, and osmium constituting one group; and ruthenium, rhodium, and palladium the other. Three of these have the chemical equivalent of 98-1/2, and the others a chemical equivalent of about half that number.
If a thermometer, made for the purpose, be placed for five minutes in the armpit, or under the tongue, it will indicate a temperature of about 98-1/2 degrees F., whether the surrounding atmosphere be warm or cold. This is the natural heat of a healthy person, and in health it rarely varies more than a degree or two.
