185 In sulphurous eddies round the weird dame
Plays the light gas, or kindles into flame.
If rests the traveller his weary head,
Grim MANCINELLA haunts the mossy bed,
Brews her black hebenon, and, stealing near,
190 Pours the curst venom in his tortured ear.—
Wide o'er the mad'ning throng URTICA flings
Her barbed shafts, and darts her poison'd stings.
[Mancinella, I. 188. Hyppomane. With the milky juice of this tree the Indians poison their arrows; the dew-drops, which fall from it, are so caustic as to blister the skin, and produce dangerous ulcers; whence many have found their death by sleeping under its shade. Variety of noxious plants abound in all countries; in our own the deadly nightshade, henbane, hounds-tongue, and many others, are seen in almost every high road untouched by animals. Some have asked, what is the use of such abundance of poisons? The nauseous or pungent juices of some vegetables, like the thorns of others, are given them for their defence from the depredations of animals; hence the thorny plants are in general wholesome and agreeable food to graminivorous animals. See note on Ilex. The flowers or petals of plants are perhaps in general more acrid than their leaves; hence they are much seldomer eaten by insects. This seems to have been the use of the essential oil in the vegetable economy, as observed above in the notes on Dictamnus and on Ilex. The fragrance of plants is thus a part of their defence. These pungent or nauseous juices of vegetables have supplied the science of medicine with its principal materials, such as purge, vomit, intoxicate, &c.]
[Urtica. I. 191. Nettle. The sting has a bag at its base, and a perforation near its point, exactly like the stings of wasps and the teeth of adders; Hook, Microgr. p. 142. Is the fluid contained in this bag, and pressed through the perforation into the wound, made by the point, a caustic essential oil, or a concentrated vegetable acid? The vegetable poisons, like the animal ones, produce more sudden and dangerous effects, when instilled into a wound, than when taken into the stomach; whence the families of Marfi and Psilli, in antient Rome, sucked the poison without injury out of wounds made by vipers, and were supposed to be indued with supernatural powers for this purpose. By the experiments related by Beccaria, it appears that four or five times the quantity, taken by the mouth, had about equal effects with that infused into a wound. The male flowers of the nettle are separate from the female, and the anthers are seen in fair weather to burst with force, and to discharge a dust, which hovers about the plant like a cloud.]
And fell LOBELIA'S suffocating breath
Loads the dank pinion of the gale with death.—
195 With fear and hate they blast the affrighted groves,
Yet own with tender care their kindred Loves!—
So, where PALMIRA 'mid her wasted plains,
Her shatter'd aqueducts, and prostrate sanes,
[Lobelia. I. 193. Longiflora. Grows in the West Indies, and spreads such deleterious exhalations around it, that an oppression of the breast is felt on approaching it at many feet distance when placed in the corner of a room or hot-house. Ingenhouz, Exper. on Air, p. 14.6. Jacquini hort. botanic. Vindeb. The exhalations from ripe fruit, or withering leaves, are proved much to injure the air in which they are confined; and, it is probable, all those vegetables which emit a strong scent may do this in a greater or less degree, from the Rose to the Lobelia; whence the unwholesomeness in living perpetually in such an atmosphere of perfume as some people wear about their hair, or carry in their handkerchiefs. Either Boerhaave or Dr. Mead have affirmed they were acquainted with a poisonous fluid whose vapour would presently destroy the person who sat near it. And it is well known, that the gas from fermenting liquors, or obtained from lime-stone, will destroy animals immersed in it, as well as the vapour of the Grotto del Cani near Naples.]
[So, where Palmira. I. 197. Among the ruins of Palmira, which are dispersed not only over the plains but even in the deserts, there is one single colonade above 2600 yards long, the bases of the Corinthian columns of which exceed the height of a man: and yet this row is only a small part of the remains of that one edifice! Volney's Travels.]
(As the bright orb of breezy midnight pours
200 Long threads of silver through her gaping towers,
O'er mouldering tombs, and tottering columns gleams,
And frosts her deserts with diffusive beams),
Sad o'er the mighty wreck in silence bends,
Lifts her wet eyes, her tremulous hands extends.—
205 If from lone cliffs a bursting rill expands
Its transient course, and sinks into the sands;
O'er the moist rock the fell Hyæna prowls,
The Leopard hisses, and the Panther growls;
On quivering wing the famish'd Vulture screams,
210 Dips his dry beak, and sweeps the gushing streams;
With foamy jaws, beneath, and sanguine tongue,
Laps the lean Wolf, and pants, and runs along;
Stern stalks the Lion, on the rustling brinks
Hears the dread Snake, and trembles as he drinks;
215 Quick darts the scaly Monster o'er the plain,
Fold after fold, his undulating train;
And, bending o'er the lake his crested brow,
Starts at the Crocodile, that gapes below.
Where seas of glass with gay reflections smile
220 Round the green coasts of Java's palmy isle;
A spacious plain extends its upland scene,
Rocks rise on rocks, and fountains gush between;
Soft zephyrs blow, eternal summers reign,
And showers prolific bless the soil,—in vain!
225 —No spicy nutmeg scents the vernal gales,
Nor towering plaintain shades the mid-day vales;
No grassy mantle hides the sable hills,
No flowery chaplet crowns the trickling rills;
Nor tufted moss, nor leathery lichen creeps
230 In russet tapestry o'er the crumbling steeps.
—No step retreating, on the sand impress'd,
Invites the visit of a second guest;
No refluent fin the unpeopled stream divides,
No revolant pinion cleaves the airy tides;
235 Nor handed moles, nor beaked worms return,
That mining pass the irremeable bourn.—
Fierce in dread silence on the blasted heath
Fell UPAS sits, the HYDRA-TREE of death.
Lo! from one root, the envenom'd soil below,
240 A thousand vegetative serpents grow;
In shining rays the scaly monster spreads
O'er ten square leagues his far-diverging heads;
Or in one trunk entwists his tangled form,
Looks o'er the clouds, and hisses in the storm.
[Upas. l. 238. There is a poison-tree in the island of Java, which is said by its effluvia to have depopulated the country for 12 or 14 miles round the place of its growth. It is called, in the Malayan language, Bohon-Upas; with the juice of it the most poisonous arrows are prepared; and, to gain this, the condemned criminals are sent to the tree with proper direction both to get the juice and to secure themselves from the malignant exhalations of the tree; and are pardoned if they bring back a certain quantity of the poison. But by the registers there kept, not one in four are said to return. Not only animals of all kinds, both quadrupeds, fish, and birds, but all kinds of vegetables also are destroyed by the effluvia of the noxious tree; so that, in a district of 12 or 14 miles round it, the face of the earth is quite barren and rocky, intermixed only with the skeletons of men and animals; affording a scene of melancholy beyond what poets have described or painters delineated. Two younger trees of its own species are said to grow near it. See London Magazine for 1784, or 1783. Translated from a description of the poison-tree of the island of Java, written in Dutch by N.P. Foereh. For a further account of it, see a note at the end of the work.]
