of
the class "four powers." I have observed in several plants of this class,
that the two lower males arise, in a few-days after the opening of the
flower, to the same height as the other four, not being mature as soon
as the higher ones. See note on Gloriosa. All the plants of this class
possess similar virtues; they are termed acrid and anti corbutic in their
raw state, as mustard, watercress; when cultivated and boiled, they
become a mild wholesome food, as cabbage, turnep.

There was formerly a Volcano on the Peake of Tenerif, which became
extinct about the year 1684. Philos. Trans. In many excavations of the
mountain, much below the summit, there is now found abundance of ice
at all seasons. Tench's Expedition to Botany Bay, p. 12. Are these
congelations in consequence of the daily solution of the hoar-frost which
is produced on the summit during the night?]

Stay, bright inhabitant of air, alight,
260 Ambitious VISCA, from thy eagle-flight!--
----Scorning the sordid soil, aloft she springs,
Shakes her white plume, and claps her golden wings;
High o'er the fields of boundless ether roves,
And seeks amid the clouds her soaring loves!

Queen of the coral groves, ZOSTERA sleeps;

[_Viscum_. l. 260. Misletoe. Two houses. This plant never grows upon the
ground; the foliage is yellow, and the berries milk-white; the berries
are so viscous, as to serve for bird-lime; and when they fall, adhere to
the branches of the tree, on which the plant grows, and strike root into
its bark; or are carried to distant trees by birds. The Tillandsia, or
wild pine, grows on other trees, like the Misletoe, but takes little or
no nourishment from them, having large buckets in its leaves to collect
and retain the rain water. See note on Dypsacus. The mosses, which grow
on the bark of trees, take much nourishment from them; hence it is
observed that trees, which are annually cleared from moss by a brush,
grow nearly twice as fast. (Phil. Transact.) In the cyder countries the
peasants brush their apple-trees annually.]

[_Zostera_. l. 266. Grass-wrack. Class, Feminine Males. Order, Many
Males. It grows at the bottom of the sea, and rising to the surface, when
in flower, covers many leagues; and is driven at length to the shore.
During its time of floating on the sea, numberless animals live on the
under surface of it; and being sp
