TYNDALL, JOHN. - CLASSICAL PAPER ON RADIANT HEAT.

The Bakerian Lecture. - Contributions to Molecular Physics. - Being the Fifth Memoir of Researches on Radiant Heat. Received March 17,- Read March 17, 1864.

(London, Taylor and Francis, 1864). 4to. No wrappers as extracted from "Philosophical Transactions" 1864 - Vol. 154 - Part II. Pp. 327-368, textillustr. Clean and fine.

First printing of a pioneer work in the investigation of the manner in which different gases and liquids conduct heat, and the high absorptive and radiative power of aqueous vapor. The two textillustrations shows his experimental equipment.

Prior to Tyndall it was widely surmised that the Earth's atmosphere has a Greenhouse Effect, but he was first to prove it. The proof was that water vapor strongly absorbed infrared radiation.

"In 1859, Tyndall began the importent series on "Radiant Heat...", for which he received the Rumford Medal in 1869 and produced his classic work, Heat considered as a Mode of Motion (1863). (Bibliotheca Mechanica). - See Milestones of Science No 191.
