Fig. 23.—The Muscular System of the Horse The work done yearly in this country by horses and mules is worth over $2,- 000,000,000. (From Ellenberger.) third of the energy used by men or animals in muscular exertion is recovered as useful work. The rest takes the form of heat within the body, and is lost so far as the production of work is concerned. These figures do not take into account the energy lost in the excreta, that expended for digestion and assimilation, or that used in maintaining the body when at rest. Allowing for all of these, a man actually con- verts about 20 per ct. of the fuel of his food into external work. The best steam engines have about the same efficiency, while the average.
