Sir B. Thompson's experiments on heat. 

 Ph. tr. 1792. 48. 



Maintains that the attiaction of loose substances for air 

 is the principal cause of thtir impeding the passage of 

 heat : thinks that elastic fluids do not conduct heat like 

 solids and liquids, from particle to particle. 



Count Rumford on the propagation of heat 

 in fluids. Ess. I. vi. Ph. M. II. 343. 

 Gilb. 244. 



Extends to liquids what he had before suggested respect- 

 ing elastic fluids. Observes, that water thickened with 

 farinaceous substances is with difficulty heated and cooled, 

 and that fruits have the same property. 



Rumford on a phenomenon observed in the 

 glaciers. Ph. tr. 1804. 23. Nich. IX. 58. 



The consequence of the expansion of water when it is 

 much cooled, and of the want of conducting power of 

 fluids.

Shows that fluids actually conduct heat when quiescent, 

 but that their motions are usually the most concerned 

 in its communication. Says that water conducts heat, 

 as it does electricity, more readily than ice : that 

 the maximum of effect of water in thawing ice must be 

 at the maximum of density : which, by neglecting to con- 

 sider the expansion of glass, he erroneously places at 



Nicholson's experiment on the conducting 

 powers of fluids. Nich. V. 197.

 and Thomson. B. Soc. Ph. n. 53, 62. 



Biot on the propagation of heat in solids.

Confirms Newton's law of decrements proportional to 

 the difference of temperature. A bar of iron was dipped 

 at one end in mercury at 21 a", and 7 holes were mada 

 in it at equal distances, in which thermometers were 

 placed : the last was never affected : the next, which was 

 at the distance of 39 inches, was never raised more than 

 1° of Reaumur. Such a rod is recommended as a tlier- 

 raometet for high temperatures : but it is probable that the 

 effect of the air would produce great irregularities. Copper 

 appeared to conduct heat somewhat more readily than iron. 

 The temperatures of thermometers were nearly, in geome- 

 trical proportion when their distances were in arithmetical 

 proportion. 



Leslie's inquiry into the nature of heat. 



Maintains that heat is communicated through gases 

 in three ways, by pulsation, by abduction, as in solids, 

 and by regression or circulation : but in liquids he finds 

 that there is no radiation. 



Parrot on the propagation of heat in fluids. 

 Gilb. XVII. 257, 369. 



BerthoUet. Chem. Stat. Nich. VIII. 134. 



Thinks that fluids must communicate heat from particta 

 to particle.
