[EVANS] SPECIFIC HEAT OF WATER OF CRYSTALLIZATION 125 
finely pulverized while the former, the anhydrous ones, were in the 
form of very fine powder. The obvious deduction is that the solid 
skould be employed in the form of a powder as finely ground as pos- 
sible. Further, means are being devised to permit of the use of a very 
much larger proportion of the solid, so that the heat absorbed by it 
may be a much larger fraction of the total. It is hoped that farther 
results will be ready for publication before long.
