Cometz

Language number and measures · A Chymical Dictionary

At a Glance

The word. A quantity expressed as one half of a drop.

In the book. Carena and Karena each give a twentieth part of a drop.

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

Historical Definition

Cometz is half a drop.

Meaning

This is a measure entry, defined by a fraction of another quantity. Its meaning depends on the historical use of “drop” in the passage being read. The dictionary does not specify a fixed volume, the liquid concerned, or an instrument that would make all drops equal.

Use in the Book

Carena and Karena each give a twentieth part of a drop. Their presence shows a vocabulary of small fractions, but does not provide a conversion into modern units. Preserve the half-drop relation when comparing quantities in a historical text.

Places to Read

Carena. A small measure expressed as a fraction of a drop.

Karena. A minute quantity measured as a fraction of a drop.
