the extract prepared from garden lettuce when in flower is not more 
than 0°02 per cent, Nevertheless, cases have been recorded in which 
the immoderate consumption of lettuce has led to unpleasant and 
even fatal results. Lettuce belongs to the natural order Composite, 
This is the first occasion on which hyoscyamine has been sia in 
plants not belonging to the natural order Solanaceae. (By 
Dymond, from the Research Laboratory of the Ph Sai

Tagetes erecta. 
The flowers contain a erystallizable substance guercetagetin, having 
the composition C*7H*°O'* +4H’O; it is the yellow colouring matter; 
its reactions in alcoholic solution are the same as those of quercetin, 
but it differs from the latter in crystalline form and solubility in 
alcohol, (Bull, Soc. Chim. [27] xxviii., 337.)

Saussurea Lappa. 
Schimmel & Co. in their Report (April, 1892) state that Kusht 
root yields one per cent. of alight yellow essential oil, which 
possesses a sp. gr. of 0°982, and a rotatory power of + 15° 20’ in a 
tube of 100 mm. It begins to boil at 275°, and about one-half goes 
over below 315°; then complete decomposition takes place, producing 
avery disagreeably-smelling vapour. When treated with soda, a part 
of the oil combines with it, and can be separated by acids. The root 
has a violet odour, but it does not seem to yield an odorous oil of that 
perfume, Messrs. Schimmel state that the odour of the oil resembles 
at first that of elecampane. After the volatilization of this odour, 
in about 24 hours, the violet odour develops, but not sufficiently 
strong to indicate that the oil could be of practical use, 
Mr, McDonell, Conservator of Forests in Kashmir, reports that 
the plant grows as high as 9,000 to 10,000 feet. The dried root 
sells at Rs. 25 per maund. It is collected by villagers and paid 
for at Tehsils. The chief purchaser is a Bombay Chinaman, 
CAMPANULACEA.
