it may be applied by flannels, wrung out of a decoction of the Hops, 
or what is better, by inclosing the vegetables in a flannel bag, and 
after boiling them a short time, press out the water, and apply 
the bag as hot as it can be borne. 
The active principle of Hops is found to reside in a peculiar 
substance, called lupulite, which has the bitterness of the Hop, and 
when heated the same smell, and by distillation with water a volatile 
oil passes over, containing a portion of sulphur and acetate of 
ammonia,

Fioots large, fleshy, black externally, white within. Stems long,

without tendrils. Zeaves alternate, a bright shining green, broadly 
heart-shaped at the base, with a long acuminated point, the footstalk 
long, slender, channeled, with a pair of slender stipules at the base. 
Flowers pale yellowish green. Barren flowers in long loose imper- 
fectly whorled racemes, mostly in pairs from the axis of the leaves. 
The fertile flowers in short racemose clusters. Berries globoso-oblong, 
smooth, fleshy, shining, a bright orange red. 
Haditat.—Hedges, thickets, woods, &c.; common. 
Perennial; flowering in June. 
The fleshy roots abound in feculent matter, combined with a bitter 
principle ; but by heat and washing this is removed, and a nutritive 
fecula is left, which may be used as a food. The smaller tubers 
attached to the large one are much the most acrid, so much so, that 
beaten into a pulp, they have been used as a stimulant in external 
application. The tender young shoots of the plant have a mild 
agreeable flavour, and are sometimes used by the poor people as 
a spring vegetable, as asparagus, and by the Moor they are said to be 
boiled and eaten with oil and salt,
