ALIMENTARY CANAL OF ARTIODACTYLA. 477 The herbivorous Mammals differ from the carnivorous more inthe character of their large than of their small intestines. Theless putrefactive nature of their food renders it susceptible of alonger retention in the body ; and the receptacular and sacculatestructures, and convolute extension, of the large intestines seemespecially designed to retard the course of the alimentary sub-stances. In the anomalous instance in a Human body, recordedby Abernethy, of a reduction of the length of the small intes-tine to about two feet, the compensation was effected by an un-us
