About this source

What it is

This printed table is a plate from Considerations on the Medicinal Use of Factitious Airs, a book by Thomas Beddoes and James Watt published in Bristol around 1794-96. It lists patients treated with different gases, their conditions, the air used, and the results, held by the Wellcome Collection.

Why it matters

Watt, better known as an engineer, also worked with the physician Thomas Beddoes on early experiments using gases to treat illness. This table shows how Watt applied his technical skills to medicine, recording real patient outcomes in a period when the therapeutic use of different airs was being tested.
