of nature for it to obtain properties from the atmosphere 

 essential to the existence of life. The passage of the blood 

 to the extremities of the vessels that convey it, is accom- 

 panied, in sweating, by another phenomenon, viz., the for-, 

 cing of the moisture through the pores of the skin, which 

 we call sweat. In the evacuations from the bowels and 

 kidneys there is never a particle of fat, and the emaciation 

 following purging or excessive staling is not due to fat 

 being carried from the body directly, but to causes result- 

 ing therefrom. In exudation, however, the oily part of 

 the blood is got rid of, as well as the watery fluid that ac- 

 companies it. You will perceive, when a horse takes his 

 first sweats, the moisture is of a thick, unctuous nature, 

 forming a lather like soap when it meets with friction 

 from the clothes or harness. As the horse's body becomes 

 freed from impurities, the sweat becomes thinner and 

 clearer, finally, having the appearance of clean water, as 

 it trickles down his legs. The skin, then, appears to be 

 the most direct way of getting rid of the fat, and not only 

 fthe most direct, but the most natural. 



The consequence of the fall of man was, that his bread 

 should be obtained by labor "the sweat of the brow" 

 was to be the lot of all of the descendants of Adam ; and 

 let horse or man be required to exert himself sufficiently, 

 the hindrances to that exertion are got rid of by those 

 natural outlets, the pores of the skin. 



The fat, in the first place, having been deposited by the 

 blood, the loss of the oily portion in sweating is replaced 

 by the absorbants working on the surplus in store, remov- 

 ing it from .where the original deposit was made ; and as 

 the sweatings are continued, exhausting all that we desire 

 to get rid of. There are probably other changes that take 

 place in the blood, one being a greater degree of fluidity, 

 perhaps occasioned by an increase of heat. It would ap- 

 pear that the abstraction of the watery particles would
