Paper, 'A comparative study of natural and artificial digestions. (Preliminary account)' by A [Arthur] Sheridan Lea

Description

Lea writes: 'When the conditions under which artificial digestions are usually carried on are compared with those under which digestion takes place in the alimentary canal, it is seen at once how imperfect the former are in comparison with the latter. The most important factors present in natural digestion, and wanting in the artificial, are: 1. Constant motion and mixing of the digesting mass. 2. Constant removal of the digestive products. 3. Continuous addition of fresh portions of digestive fluid.'
