Pneumatic_Institution--Humphrey_Davy

The Pneumatic Institution (also referred to as Pneumatic Institute) was a medical research facility in Bristol, England, in 1799–1802. It was established by physician and science writer Thomas Beddoes to study the medical effects of gases, known as factitious airs, that had recently been discovered. Humphry Davy headed the Institution's laboratory, examining the effects of laughing gas on himself and others, and James Watt designed much of the lab's equipment.
