    shorter; and by the combined action of these fibres, the food is gradually propelled through the whole length of the intestinal canal. The motion thus exci- ted may be distinctly seen in an animal recently kill- ed and in some it continues a considerable time after death. The intestine, however, is not entirely com- posed of muscular fibres: its internal surface is lined with a fine nervous and vascular membrane, which is endued with exquisite sensibility, and has the power of forming on its surface a mucous substance, which serves to protect it from the action of acimonious bo- dies. Beside the muscular and nervous coat, there is another which enters into Vim composition of the intes- tine : this is a thin membrane cnUedperitonceiun. The peritonaeum not only forms the third and external coat, it likewise envelops all the organs contained in the abdomen, forming their external coat, and is closely connected with them, and is then so reflected as to form a kind of sac, in which they are all enclosed.— Thus are the intestines composed of three coats, which are closely in contact with each other; the peritonaeal the muscular, and the nervous coat. We have yet to describe the course of the lacteals, or those vessels which take up the chyle or nutritious parts of the food. We have before observed that they are spread upon the mesentery, whence they pass on toward the spine, becoming larger and less numerous in their progress ; at length they terminate in a large tube, which runs along the spine, and is named the thoracic duct: this pours its contents into a large vein near the heart, to which part it is immediately after conveyed, and converted into blood. The kidneys are two glandular bodies, situate with- in the loins; their office is to separate urine from the blood. The urine, thus separated, is conveyed by two tubes of considerable length, termed ureters, into the bladder, which is composed of three coats, like those of the intestine ; and when it has received a suf- ficient quantity of urine to stimulate its muscular fibres
