Excerpt from The Southern Planter, Vol. 18: Devoted to Agriculture, Horticulture, and the Household Arts, August, 1858D1. Playfair afterwards went on to tell them, in regard to warmth, that it was up to a cer tain point an equivalent for food. He said, The average tempe1ature of the bodies of our cattle is about 100 degrees, 01 more than 40 deg1ees higher than the ordinary temperature of this climate. Hence there must be some provision in the animal body to sustain the heat which 1s absolutely necessary tor the p r formance of the organic functions. The air, being~so much colder than the body, must con stantly' withdraw from it heat, and tend to lower its tempe1atu1e. Whence, then, comes the fuel for the production of the heat What the doctor said was, in other words, that 'the heat required by the animal's body being 100 degrees, when the temperoatu1e was below that the exchanges were against the animal. If the bodily heat was only 60, it must be made up to 100 by fuel. What fuel? Why, food. Surely, then, breeders ought, for the sake of economy, to keep up the animal heat. The doctor quoted Liebig in confirmation of his views. Were Liebig, to go na ked like certain savage tribes, or if in hunting and fishing we were exposed to the same de gree of cold as the Samoyedes, we should be able with ease to consume ten pounds of ¿esh, -and perhaps a dozen of tallow candles into the bargain, as warmly clad travellers ha1e related with astonishment of these people. We should then also be able to take the same quantity of brandy or train-oil without bad effects, because mthe carbon and hydrogen of these substances cwould only suffice to keep up the equilibrium ~between the temperature of the external air Maud that of our bodies. Dr. Playfair him 11 self afterwards said: The enlyxuse of clothes.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
