C. L. Speyers — Solubilities of Some Carhon 



condition, neither supersaturated nor undersaturated. The 

 thermometer was the one used for the solubilities and the tem- 

 perature is certain to 0-1°. 



The uncertainty in the density is about 3 units in the third 

 place in extreme cases ; in general it is 2 or 3 units in the 

 fourth place, the pycnometer holding between 8*5 and 9*8^'' 

 and the weighings being made to milligrams. 



The following tables give the temperatures and correspond- 

 ing densities ; namely, weights in grams reduced to vacuum of 

 one cubic centimeter of solution.
