Historical Definition

Amnis alcalisatus is water passing through the earth’s chalk, from which Alcali is obtained.

Meaning

The name describes a water through what it passes through and what can be obtained from it. That relational structure is useful: the entry does not simply equate the water itself with dry Alcali. It distinguishes a carrier or source from the product associated with it. The historical wording leaves the precise extraction and the nature of the “chalk” to other evidence.

Read this beside Alcali, where extraction from ash or calx is explicitly described. The two entries show different ways the dictionary organizes substances by origin and preparation. They should not be forced into a single modern account of naturally occurring alkaline water.

Places to Read

Alcali. Salt defined through extraction from ash or calx.

Calx lignorum. A direct identification of a calx as ash from wood.
