Historical definition

Cohos is everything contained by the skin throughout the whole body.

Meaning

The definition takes the skin as a boundary and gathers what it contains into a single term. It is broader than the name of one organ, fluid or tissue. “Everything” is important: replacing Cohos with a particular internal substance would narrow the definition beyond what the compiler says.

Use in the book

Corpus gives another general word for a bodily or material subject, while Excrementa identifies things expelled as superfluous. Cohos describes inclusion within a boundary; Excrementa describes the book’s account of removal. Their contrast can help a reader follow changes between the body as a whole and particular products of its activity.
