PROFESSOR W. N. HARTLEY OH THE 
Three solutions of oxynarcotine were examined, this solution, which was kept for 
some time after the notes written below had been taken, yielded a spectrum from 
which the curve was drawn. It was found however that the liquid had undergone 
great change, so a second solution was made which yielded the dotted curve when quite 
fresh.
