The selective absorption in this substance is very slight, beginning at a thickness of 
5 millims. and ending at the next thickness of 4 millims. in a solution of 1 grm. in 
5000 cub. centims. (alcohol). 
This solution gives a blue fluorescence similar to that given by pseuclaconitine and 
apomorphin e-hydrochloride.
