Diathermancy and Athermancy — Transmission of Thermal Rays. —
Diathermancy is the term used to express the power which bodies have of
transmitting heat, and bears the same relation to radiant heat that transparency
docs to light.

What are diathermancy and atherni ancy ? The power which bodies have of
transmitting heat is called di- athennancy, analogous to transparency in light. The
power of stopping radiant heat is athermancy, and corresponds to opacity in light.

Tn other words, the athermancy of the air varies with its relative humidity. The
nearer it is to that state in which it begins to deposit cloud or fog, the more
opaque is it to dark heat, and it is this, and not merely the absolute quantity of the
vapour ...

by night, plant-life would be destroyed, and the earth would be uninhabitable. It
should be stated, however, that recent investigations cast some doubt on the
athermancy of aqueous vapour, and even seem to show that it is as
diathermanous ...
