Tliree hundred cubic centimeters of 1 per cent sodium chloride solution were heated to 70° C, 

 with 5 grams, )'. e., an excess of preparation 21, and filtered on a steam-jacketed funnel. On cooling, 

 the filtrate rapidly deposited a large crop of apparently rhomboliedral crystals. The residue 

 undissolved by the hot 1 per cent brine was washed with the same weak brine heated to 70°. On
