THB INTESTINES. 48i The Laege or Double Colon (Figs. 282, 283, 284).—This intestine begins at the caecum, and terminates by suddenly contracting at the origin of the small colon. Length—Capacity.—It is from about 10 to 13 feet in length, and has a medium capacity equal to 18 gallons. Form—General arrangement.—Removed from the abdominal cavity, and extended on a table or on the ground, this portion of the intestine appears as a voluminous canal, offering a succession of dilatations and contractions ; its surface being traversed by longitudinal bands, and sacculated and furrowed transversely for a great part of its extent, exactly like the caecum. It is also doubled in such a manner as to form a loop, the two branches of which are of equal length, and are held together by the peritoneum, which is carried from Fig. THE COLON OF THE HORSE. 1, First portion ascending to form the supra-sternal flexure; 2, second portion descending to form the pelvic flexure, 7 ; 3, 6, longitudinal muscular bands; 4, point of the caecum, 5; 8, duodenum; 9, small intestine. one to the other; so that the terminal extremity of the large colon returns towards the point of its origin. But this colic flexure, owing to its length, could not be contained m the abdomen ; and it is therefore doubled in its turn from above to below, and from right to left (at the points f, f, in Fig. 283), forming curvatures which will be noticed presently. From this circumstance, it results that the large colon, studied in the abdominal cavity, is divided into four portions lying beside each other in pairs ; so that a transverse section of that cavity, made in front of the base of the csecum, would give for this intestine the results indicated in Fig. 285. Course and Relations.—In following the course of the large colon from its origin to its termination, in order to study its four portions in their normal relations, the fol
