SALICYLIC ALDEHYDE. 
he sample of salicylic aldehyde from Scbuchardt was recti¬ 
fied by redistillation. The portion taken had a constant boiling 
point and the specific conductivity was 5.98 X l(r 6 .

FURFUROL. 
The sample of furfurol from Merck was treated with fused 
calcium chloride over which it stood for several weeks. It was 
then distilled and the distillate again distilled. The portion 
coming over between 156° and 158° at 744 mm. pressure was 
collected and its specific conductivity was 2.4 X 10 -5 . 
1 Apparently not quite all dissolved. After cooling became a very vis¬ 
cous mass.
