The first three freezing points of this series were well marked, and accompanied by 
a considerable formation of precipitate. 
At 16 atoms of tin the freezing point was a very steady temperature, and there 
was much precipitate at the moment of reading. 
* Determined the day after the previous reading, 
t Residue of the preceding alloy after the removal of I34'6 grams.
