therefore, corresponds to an alloy of the formula AggSb, a body that is known to 
exist. An angde such as we have here is not the sort of indication of the existence 
of a compound that the theory would lead us to expect. Indeed, another examina¬ 
tion of this part of the curve with especially pure antimony would be needed before 
it would be safe to assert that the angle is at exactly AggSb.

The numbers below the curve give the Centigrade temperature. 
The numbers above the curve give the atomic percentage of antimony or bismuth. 
The first series, Table VIIIa., which ends at 53 atoms of antimony, involved the 
maintenance of the alloy at a high temperature for a good many hours, and, as tlie 
notes show, there was a considerable loss of metal. Consequently we feared that the 
latter part of the series might not be trustworthy. We therefore carried out a new 
series, Table YlIIc., beginning near the eutectic point. The result of this is given 
on a large scale above the main curve, and seems to show that the eutectic alloy has 
not a formula, although it is not very far from 40 atomic per cents, of antimony,
