Ios

Body disease and historical medicine · A Chymical Dictionary

At a Glance

The word. A name directing the reader to poison.

In the book. Contrast Oleitas rerum, which names sulphur as a principle present in things.

A place to read. The historical definition below, 1650 dictionary, unnumbered definition page 28; facsimile PDF page 356.

Historical Definition

Ios is poison.

Meaning

The entry supplies a broad equivalent, without identifying a particular poisonous material. Its brevity is useful: encountering Ios alone does not establish an ingredient, dose or means of preparation. A surrounding passage may supply those particulars, but the dictionary does not.

Use in the Book

Contrast Oleitas rerum, which names sulphur as a principle present in things. Ios identifies a harmful category rather than one of the general principles by which the book explains their composition.

Places to Read

Oleitas rerum. Oiliness of things interpreted through their sulphur.
