MUSCULAR POWER. 125 In a great number of muscles, the fibres, instead of running parallel to one another, are made either to converge, or to diverge, in order to suit parti- cular kinds of movements ; and we frequently find that different portions of the same muscle have the power of contracting independently of the rest, so as to be capable of producing very various effects, according as they act separately or in combination. This is exemplified in the musc . Der Mensch. Anthropology; Human anatomy; Physiology. Fie.l. GeJiim -JiücMnij-itniksrrnne luiffaifiilef.

DIGESTION 261 pteropods. Proteases and sucrases are secreted into the gut in other gastropods (vide infra) (46). Limulus and pycnogonids among arthropods retain a degree of in- tracellular digestion. The food of Limulus consists of polychaetes and lamellibranchs which are torn up by the gnathobases of the walking legs before being swallowed. Enzymes, including proteases, are released into the stomach cavity but the breakdown of proteins is completed intracel- lularly, within the cells of the digestive gland, by an intrac . Der Mensch.
