On the Thermo-electric Properties of Solid Mercury. 
By Dr W. Peddie and the late Alex. B. Shand, Esq. 
(Read February 18, 1901.) 
(Abstract.) 
This paper contained an account of a redetermination of the 
thermo-electric position of solid mercury, by a method described 
in a note read last session. The only difference was that, by the 
use of three galvanometers, simultaneous readings of the deflection 
due to the Hg-Fe circuit, and of the deflections due to thermo- 
electric circuits giving the temperatures of the two Hg-Fe junctions, 
were taken. 
The results confirmed those previously obtained. 
It may be said that the line of solid mercury on the thermo- 
electric diagram is practically parallel to the iron line at ordinary 
temperatures, and that, if produced, it meets the line of copper at 
or near, its intersection with the ordinate of 0° C.
