From the above it is evident that there is a gradual decrement* 

 in the values obtained, and therefore we are not justified in 

 taking, as is done by Mr. Sabine (page 459), the mean of these 

 values and calling them " the conducting powers of the metals in 

 a fluid state" (I.). 



Again, in our paper (p. 179) we state that "if to melted 

 bismuth traces of tin or lead be added, a decrement, and, on 

 further addition, an increment in the conducting power will be 



* A slight error in the determinations materially affects some of these 

 numbers, owing to the very small amount of metal allo)"ed with the mercury. 

 Thus the conducting power of the silver amalgam containing 0*025 per cent, 

 of silver was found equal to 10*930 and 10*923 ; and if we deduce from these 

 the values for the conducting powers of silver, we shall find them equal to 

 72*5 and 50*9. Again, we find the conducting powers for zinc deduced 

 from the observations made with the amalgam containing 0025 per cent, 

 equal 93*2, 95-4, and 102*0.
