GUT MANUFACTURE, an unpleasant though rather importZnt branch of manufac ture, the operations of which consist in preparing the membranes of animal intestines for various useful purposes. The French call it boyawderie, from boyau, intestine, and have placed it under stringent legal regulations, on account of its offensive and pestifer ous character, especially when conducted in a populous quarter of a town, as at the Rue de In Boyawderie, in Paris. One branch of gut manufacture has been described under GOLDBEATEHS' SKIN. Cat-gut, as it is called, is made from the intestines of sheep, are first cleansed and freed from loose fat, then prepared by soaking and partial putrefaction, to loosen the different membranes of which the intestine is composed. These are then separated by scraping, then further soaked in clean water and scraped separately. After this, they are treated with a solution of potash, and drawn by women through a sort of thimble, and sorted for twisting into threads. They are then exposed to fumes of sulphurous acid, given off from burning sulphur, which deodorizes them, and prevents subsequent putrefaction. The small intestines are used for cat-gut. the large intestines are simply scraped and salted, for the use of sausage-makers and by confectioners, and for tying over preserve and pickle jars, etc. The coarser kinds of eat-gut strings are used for pulley and lathe bands, strings for archery-bows, drill-bows, hatters-bows, and other purposes where a strong cord subject to friction is required; the finer kinds are twisted into whip-cord, and are used for fishing-tackle and the strings of musical instruments. For the latter purpose a very superior quality is required,
The best, called Roman strings, are made chiefly at Milan. Our manufacturers have never been able to equal these, and this is attributed by sonic to the fact that the Italian sheep are much' leaner than ours, and the membranes of lean animals are tougher than those which arc highly fattened and rapidly fed up to Marketable size.
GUTS HUTHS„TOtt. CIIIUSTOPH. FRIEDR., a German instructor of youth, was b. at Quedlinhurg, in Prussian Saxony, Aug. 9, 1759, studied at Halle, and subsequently became attached to Salzmann's institution at Schnepfenthal. There lie gave himself specially to the elaboration, theoretical and practical, of gymnastics (q.v.) as a branch of education; and from hint it has passed into the curriculum of other German institu tions. In 1793 Guts Muths published his Gymnastik fib. die Jugend, which has become a classic work on the subject, and the basis of all subsequent treatises. Besides several other works ori his favorite subject, Guts _Moths holds a distinguished place as a writer on geography. He died iu 18,19. His centennial anniversary was celebrated Aug. 9, 1859, at Schnepfenthal.
