The weight of the alloy employed for the first experiment was 

 about 300 grms., of which the non-crystalline part weighed about 

 1 50 grms. : in the second experiment the weight of the alloy was 

 about 250 grms., and the non-crystalline part weighed about 50 grms. 



The addition of more tin did not cause any further separation into 

 two masses. The following Table gives the results of the experiments 

 made with the other alloys : 



* This was re-fused in order to remove more completely the crystallizable part 

 of the alloy ; and as soon as a part had solidified, the rest was poured off. That 

 which first solidified was analysed.
