_and skatole when extracting sugar from molasses ‘by the strontia method. Everybody, —

__ baryta, will remember the nauseous, sometimes almost unbearable fecal smell of the | 
_ vapours, evolved by the molasses on continued boiling with the alkaline earths. It isa

for the purpose of turning to advantage their comparatively high content of ammonia. 
Indole and skatole were ascertained to be the cause of this smell. The indole showed — 
the known colour reaction and melted at 52°, skatole at 95°. Both yielded a picrate — 
- and were successfully analyzed. von Lippmann supposes that the residues of albu- 
_ mines and their resolution products-are responsible for the yield of indole and skatole.
