The alveoli measured l-200th of an inchin length, by in breadth; thewidth of the septa being 1-lOOOth of aninch. The smaller alveoli measuredl-2.)0th of an inch in length, and l-300thin breadth.

The di-ameter of these cells varies from g^^th to 3I o^^ of ^^ inch ; but, nearthe pylorus, it is as much as jljjth. of an inch. In the bottom of thecells, minute openings are visible, which are the orifices of perpen-dicular glands embedded, side by side, in bundles in the substance ofthe mucous membrane, and composing nearly the whole structure.^These tubular follicles vary in length from one-fourth of a line tonearly a line. They are longer and more closely set towards the py-lorus than elsewhere, their length being equal to the thickness of themucous membrane of the stomach, which varies. The office of the tubular follicles, it has been thought, is to secretethe gastric fluid, during digestion; for in the intervals they are atrest. They are formed by inflections of basement membrane, withcylindrical epithelium resting upon it. One of them is represented intlie marginal f
