COMPLETE FREEZING-POINT CURVES OF BINARY ALLOYS.

At the end of the experiments the alloy was weighed and found to be 270 grams, 
while from the statement of the weights of antimony and silver used, the weight 
should have been 285 grams. Some of this loss is due to metal adhering to the 
pyrometer, stirrer, and crucible, but the missing 1 5 grams cannot all be accounted 
for thus ; there has certainly been a loss of alloy by volatilization or splashing. This 
fact renders the atomic percentages of the latter part of the series somewhat 
uncertain.

t The ingot when taken ont of the crucible was bright; it weighed 360-8 gram.s. The calculated 
weight was 366‘46 grams. As the loss was probably for the most part antimony, we see that there was 
during the experiment a loss of 2 per cent, of this metal. Splashing, spitting, and oxidation will 
account for this,
