Coostrum

Body disease and historical medicine · A Chymical Dictionary

At a Glance

The word. A particular part of the diaphragm.

In the book. Cohos gives a comprehensive term for what the skin contains, whereas Coostrum points to one bodily location.

A place to read. The historical definition below, 1650 dictionary, unnumbered definition page 17; facsimile PDF page 345.

Historical Definition

Coostrum is the middle part of the diaphragm.

Meaning

The gloss is anatomical and narrowly locational: it specifies a middle part. It gives no further division of that structure and attributes no separate function to it. The headword should therefore be kept at the scope of the original description.

Use in the Book

Cohos gives a comprehensive term for what the skin contains, whereas Coostrum points to one bodily location. The contrast illustrates how the dictionary moves between whole-body vocabulary and names for parts. No additional bodily identification can be recovered from the similarity of the two words alone.

Places to Read

Cohos. The contents of the body considered within the boundary of its skin.
