460 DR. CHARLES H. LEES ON THE EFFECT OF TEMPERATURE ON THE 



Glycerine. (Pure, Sp. g. = 1'263.) 



Obtained by filling the brass tube with the liquid and slowly freezing it from below 

 upwards by dipping the base of the tube into liquid air. 



CURRENT in Heaters '991 ampere. C 3 = '982. k r = '00971 



With these results may be compared the following values for k for the liquid : 



H. F. WEBER, ' Berliner Ber.,' 1885, p. 809, '00067, 9 C. to 15 0. 

 GRAETZ, 'Ann. der Phys.,' 25, p. 337 (1885), '00062 at 13 C. 

 LEES, 'Phil. Trans. Roy. Soc.,' A, vol. 191, p. 424 (1898), '00068 at 25 C., 

 00061 at 48 C. 



Probably liquid, as the melting-point of glycerine is given by RlCHTER as 17 C.
