    In the small deer from Prince of Wales's Island in the East Indies, which differs from the rest of its tribe in having no third cavity to the stomach, the coecum is larger, longer, and the rectum of unusual size, although the course of the colon is nearly the same, as will be seen in the engraving.* In a small animal of the deer kind, smaller than that from Prince of Wales’s Island, and resembling it in the gall-bladder and other respects, the turns of the colon are different, although in no very great degree; but the difference is suffi- ciently strongly marked to demonstrate, that nature deviates from any particular structure, whenever a variety of the same animal is produced: and the annexed engraving is to shew this particular fact.-f- In the hog-deer from the East Indies, the turns of the colon are more extensive than in the species already de- scribed.]; In the East Indian deer, they are probably not more exten- sive, but put on a different form.§ In the common deer, the duodenum almost immediately upon leaving the stomach crosses the body to the left side, without any mesentery. The mesentery of the jejunum and ilium, instead of being oblique, is almost horizontal. The ilium enters the colon, not upon the edge where the meso- colon is attached, but upon the anterior surface, and is attached to the coecum by a meso-colon. The coecum is one foot long. The course of the colon is shewn to differ from that in others of the deer tribe, in the turns being horizontal instead of perpendicular.|| * Tab. CXXVH. t Tab. CXXVIII. $ Tab. CXXIX. § Tab.
