ON NARCISSUS. 
M. Jourdain has ascertained that the peculiar principle resides 
in nearly the same proportions, in the narcissus poelicus, la- 
zetta, as in the pseudo-narcissus. The N. Jonquilla contains 
a more viscid matter than the preceding species. 
According to M. Jourdain, the bulb of the N. pseudo-nar- 
cissus contains, in 100 parts, 
Narcitine, 57 
Gum, 6 
Tannin, 24 
Lignin, 28 
Saline matter and vol. o 1. 
The flowers of the narcissus contain scarcely 25 per cent, 
of narcitine. 
The opinion of M. Jourdain, which agrees with that of 
MM. Avuret, Waltecamp, Dufresnoy, in establishing the eme- 
tic properties of narcissus, is contrary to the facts observed 
by MM. Loiseleur Deslongchamps and Caventou; it would 
therefore be useful to repeat these experiments, and to ascer- 
tain whether the narcissus collected in the department of Seine 
possesses the same properties as that which was examined by 
M. Jourdain.
