This alloy, Hke the preceding, has two temperatures of maximum den- 

 sity or minimum volume ; the one at 133° C, the other at some point 

 far below zero.

 iodides of Silver, between 0° C. and 750° C. 



The experimental results obtained with the last two alloys were less 

 consonant than those of the other alloys, which might be predicted from 

 the nature of the alloys in question.
