SPECIFIC GRAVITY TABLES. 



105 



XXXVIII. Alloys. 



For the following table completeness is not claimed. The compiler has 

 merely sought to tabulate the more important published determinations of 

 the Specific Gravities and Melting Points of Alloys, including only those alloys 

 whose composition admits of moderately simple formulas. Some of these 

 substances are, doubtless, definite chemical compounds; hut the formulas, in 

 most cases, merely indicate the proportions of the metals in the alloj's.
