    tlie whole and, after a short maceration, or, as frequently happens in the dead subject, spontaneously, may be readily stripped off in large white sheets, either Fig 199 alone, or accompanied by adherent portions of the deeper layers. The proper mucous membrane, measur- ing on the average 03', possesses numerous conical papilla of 0-04—0-05' in length, and consists of ordi- nary connective tissue, with fine elastic fibres, among which, however, as Briicke and I have ascertained, a great quantity of longitudinal bundles of smooth muscles, and in addition, more isolated groups of ordinary fat cells and small racemose mucous glands, may be observed. The oesophagus is moderately provided with lymphatics and blood-vessels ; the latter send loops into the papillae and form at their bases, a not very wide network, like that in the pharynx. Nerves may also be met with in considerable numbers in the mucous membrane, containing fine fibres of O0012'—00015', but I have not yet succeeded in tracing them into the papilla, nor in observing divisions, nor the modes in which they ter- minate.

Those parts which constitute what may, more strictly speak- ing, be called the alimentary canal, are the least fixed of all which compose the alimentary tract and are almost invariably attached by special membranous bands—the mesenteria—in the great cavity of the abdomen, lined by the peritoneum.
