    that a thermometer always registers the same de- gree of heat when placed in any internal part of the body, and this in spite of the ever - changing temperature of the surrounding atmosphere. On re- ference to this table, you will see the relative propor- tions of carbon, hydrogen, and oxygen, in the different non-nitrogenous substances. Carbon. Hydrogen. Oxygen. Starch ... 44-44 6-17 49-39 Cane sugar 4210 6-43 51-47 Grape sugar 40-0 6-66 53-34 Hogs’ lard 79 09 11*16 9-75 Mutton suet 78-99 11-70 9-30 Olive oil 77 21 13-36 9-43 Cod-liver oil 77-44 11-27 11-29 Butter ... 65-60 17-60 16-80 Alcohol ... 52-18 1304 34-78 In the sugars, the oxygen and hydrogen exist in the proportion to form water. In the oils, the hydrogen is in excess of the oxygen to form water, and hydrogen is the substance which gives out most heat by its oxidation. It is quite clear, therefore, that the oils are the most important heat producers, as they have by far the greatest proportion of hydrogen. Alcohol, according to its composition, ought to give out more heat by oxidation than the starches; whilst another of its properties is its high osmotic equiva- lent. By that I mean it is very readily absorbed into the system, and is therefore in action long before the starches are turned into soluble dextrine, or even the
