Fatigue and Disease.

The fles-li of overdnven animals j«. now j generally regarded <i« unlit for food. It is also well known that death sometimes lesults from over-exertion For several years eminent experts have been carefully studying the mfluenct of fatigue in cau-ing actual disease. It w;is fiist shown ;hat fatigue in animals might give n-e to a ijphoid itatn. fo 1 lowed Jreciue:itlv by death -with rapid decomposition. Later the same was pioved to bo tine of human beings. Revjll.oc?, in 1880, made it evident that ovenvoik might bring on either a typhoid state, or, less often, that, form of cnuhiic disease known as ' nritable henit."' Fp b.ivs that multitudes of cases of fever oceuinng in the practice of physicians might properly be classed among fevers due to fatigue or overwoik. The most complete trentise on the subject is that of Yictoi Rendon. According to thi« writer, all diseased states diva to fatigue are of a typhoid character, of which there are three Joims The first is wilhodi fever, is slight, and is soon recovered from by re&t. If the overwork is sufficiently prolonged there is a tine fever, but with an alteration only of the fluids of tlie organisation. Still more arduous or prolonged work Is followed by fevti with ilterntion not only o! the fluids, bur al-o of the solids, es pecui'!\ ot the he.ul blood-ves-,els, k.dreys, and spiml r oid This third foim octuis m over di :ven animals, in inns?-, ■who work by day and watch by night, in se>Miers after prolonged foiced marches, and m pupils wheise bidins aie overworked at school. In ihe normal action of the physical system there is a continual product ie>n m ithiu jt of vjiiou« kinds of wa.ste eh'ments. The muscles, pioducp certain kincK and the brain others- These are neit only produced in much i_ r reater abundance by eneiwoik, but the weakened eliminating organs ,ne unable to j^et rid of them. The le-ul' is that they .ice iiinul.ite in th'j system, mid actually poison it. Heine lauguoi, piostiation, musculai p. tins, the typhoid state, and fevei. In an over diiven fox the ejuantity of a .single one eif these poihonou- waste elements was found to be ten times more than noimal. The^e poisonous elements and the rebiilting synip toms -will diffei according to the chaiaclei ol the overwoik It will thus lie seen how veiy unfit ior food is the He-h of ovcidnven cattle.
