Abstract
WE learn from the researches of Tyndall that the radiation from heated air streaming from about a copper ball heated to near redness was just detectable, but scarcely measurable with the most delicate apparatus then in existence.He was also able to show that other gases, under like conditions radiated, some to a much greater extent than air, and he formed a table in which the different gases experimented upon stand in the order of their radiating powers.This at present comprises about the sum of our knowledge of this important matter.The recent invention of several forms of extremely delicate heat• measuring apparatus now enables us to deal sue• cessfully with quantities of heat so minute, that the ordinary thermopile gives no indication of their existence.The apparatus used in the following investigation is something of an improvement upon that formerly here devised and described* which improvement has been effected by the substitution of a junction of the bismuth, antimony and tin alloys in place of the iron-nickel couple formerly employed.By a peculia.rmethod of casting these alloys into thin leaves it is possible to give them a certain amount of temper by which their tenacity is considerably increased, so that .byskill and patience they can be worked into bars as small as O'002 cm thick, and O'03 cm wide.More difficulty however being experienced with the alloy of bismuth and antimony.To avoid too
