green fluorescence; it consists of two longish cotyledons 
surrounded by albumen; the cell contents of bath appear 
granular. 
Chemical composition—Some seeds crushed, and treated 
with water for a few minutes, produced after filtering a 
pale yellow fluid with.a marked green fluorescence ; this was 
destroyed by alkalies and restored by acids, A further examina- 
tion of the seeds was made by exhaasting them with rectified 
benzine, rectified spirit, and water acidulated with hydro- 
chloric acid. The benzine solution was of a pale yellow colour, 
and upon evaporation yielded a rich reddish brown oil, havin 
no very marked odour, and a nauseous taste. The tincture 
made with rectified spirit was of a deep red, like Tra. Lavandule 
Comp., very opaque and highly fluorescent. Upon evaporation 
it yielded a soft extract of the colour of Dragon’s blood, and 
having the odour of Cannabis indica. This, when exhausted 
with water, gave a pale red solution with a green fluorescence, 
which, when treated with a solution of oxalate of ammonia, 
threw down the red colouring matter and became pale yellow. 
but retained its fluorescence. The remainder of the spirituous 
extract, after complete exhaustion with water, consisted of a 
soft resin of a deep carmine lake colour, having a heavy nar- 
cotic odour like resin of Cannabis indica. The portion treated 
with acidulated water yielded a pale sherry-coloured fluorescent 
solution, which, upon evaporation, gave a soft yellow extract, 
with an odour like honey ; the greater part of this dissolved in 
rectified spirit, forming a yellow fluorescent solution ; this, 
after filtration, was evaporated to a thin syrup, and upon 
cooling formed a dark brown mass, The seeds contain two 
alkaloids, Harmaline, C'* H'4 N2 O, discovered by Gobel in 
1837, and Harmine, C'* H!? Ne O, discovered by Fritszche 
in 1847, The yield of the two alkaloids according to Fritszche 
is 4 per cent., of which one-third: is Harmine and two-thirds 
Harmaline. These two substances have be
