P. 136. _Addition to the note on Tropaeolum_. In Sweden a very curious phenomenon has been observed on certain flowers, by M. Haggren, Lecturer in Natural History. One evening be perceived a faint flash of light repeatedly dart from a Marigold; surprized at such an uncommon appearance, he resolved to examine it with attention; and, to be a.s.sured that it was no deception of the eye, he placed a man near him, with orders to make a signal at the moment when he observed the light. They both saw it constantly at the same moment.

The light was most brilliant on Marigolds, of an orange or flame colour; but scarcely visible on pale ones.

The flash was frequently seen on the same flower two or three times in quick succession, but more commonly at intervals of several minutes; and when several flowers in the same place emitted their light together, it could be observed at a considerable distance.

This phaenomenon was remarked in the months of July and August, at sun-set, and for half an hour after, when the atmosphere was clear; but after a rainy day, or when the air was loaded with vapours, nothing of it was seen.

The following flowers emitted flashes, more or less vivid, in this order:

1. The Marigold, _(Calendula Officinalis)_.

2. Garden Nasturtion, _(Tropaeolum majus)_.

3. Orange Lily, _(Lilium bulbiferum)_.

4. The Indian Pink, _(Tagetes patula et erecta)_.

Sometimes it was also observed on the Sun-flowers, _(Helianthus annuus)_.

But bright yellow, or flame colour, seemed in general necessary for the production of this light; for it was never seen on the flowers of any other colour.

To discover whether some little insects, or phosphoric worms, might not be the cause of it, the flowers were carefully examined even with a microscope, without any such being found.

From the rapidity of the flash, and other circ.u.mstances, it might be conjectured, that there is something of electricity in this phaenomenon.

It is well known, that when the _pistil_ of a flower is impregnated, the _pollen_ bursts away by its elasticity, with which electricity may be combined. But M. Haggren, after having observed the slash from the Orange-lily, the _anthers_ of which are a considerable s.p.a.ce distant from the _petals,_ found that the light proceeded from the _petals_ only; whence he concludes, that this electric light is caused by the _pollen_, which in flying off is scattered upon the _petals._ Obser.

P. 153. _Addition to Avena._ The following lines were by mistake omitted; they were designed to have been inserted after l. 102, p. 153.

Green swells the beech, the widening knots improve, So spread the tender growths of culture'd love; Wave follows wave, the letter'd lines decay, So Love's soft forms neglected melt away.

P. 157. _Additional note to Bellis._ Du Halde gives an account of a white wax made by small insects round the branches of a tree in China in great quant.i.ty, which is there collected for economical and medical purposes: the tree is called Tong-tsin. Description of China, Vol. I. p. 230.

_Description of the Poison-Tree in the Island of JAVA. Translated from the original Dutch of_ N. P. Foerich.

This destructive tree is called in the Malayan language _Bohon-Upas,_ and has been described by naturalists; but their accounts have been so tinctured with the _marvellous,_ that the whole narration has been supposed to be an ingenious fiction by the generality of readers. Nor is this in the least degree surprising, when the circ.u.mstances which we shall faithfully relate in this description are considered.

I must acknowledge, that I long doubted the existence of this tree, until a stricter enquiry convinced me of my error. I shall now only relate simple unadorned facts, of which I have been an eye-witness. My readers may depend upon the fidelity of this account. In the year 1774 I was stationed at Batavia, as surgeon, in the service of the Dutch East-India Company. During my residence there I received several different accounts of the Bohon Upas, and the violent effects of its poison. They all then seemed incredible to me, but raised my curiosity in so high a degree, that I resolved to investigate this subject thoroughly, and to trust only to _my own observations._ In consequence of this resolution, I applied to the Governor-General, Mr. Petrus Albertus van der Parra, for a pa.s.s to travel through the country: my request was granted; and, having procured every information. I set out on my expedition. I had procured a recommendation from an old Malayan priest to another priest, who lives on the nearest inhabitable spot to the tree, which is about fifteen or sixteen miles distant. The letter proved of great service to me in my undertaking, as that priest is appointed by the Emperor to reside there, in order to prepare for eternity the souls of those who for different crimes are sentenced to approach the tree, and to procure the poison.

The _Bohon-Upas_ is situated in the island of _Java,_ about twenty-seven leagues from _Batavia,_ fourteen from _Soura Charta,_ the seat of the Emperor, and between eighteen and twenty leagues from _Tinksor,_ the present residence of the Sultan of Java. It is surrounded on all sides by a circle of high hills and mountains; and the country round it, to the distance of ten or twelve miles from the tree, is entirely barren. Not a tree, nor a shrub, nor even the least plant or gra.s.s is to be seen.

I have made the tour all around this dangerous spot, at about eighteen miles distant from the centre, and I found the aspect of the country on all sides equally dreary. The easiest ascent of the hills is from that part where the old ecclesiastick dwells. From his house the criminals are sent for the poison, into which the points of all warlike instruments are dipped. It is of high value, and produces a considerable revenue to the Emperor.

_Account of the manner in which the Poison it procured._

The poison which is procured from this tree is a gum that issues out between the bark and the tree itself, like the _camphor._ Malefactors, who for their crimes are sentenced to die, are the only persons who fetch the poison; and this is the only chance they have of saving their lives.

After sentence is p.r.o.nounced upon them by the judge, they are asked in court, whether they will die by the hands of the executioner, or whether they will go to the Upas tree for a box of poison? They commonly prefer the latter proposal, as there is not only some chance of preserving their lives, but also a certainty, in case of their safe return, that a provision will be made for them in future by the Emperor. They are also permitted to ask a favour from the Emperor, which is generally of a trifling nature, and commonly granted. They are then provided with a silver or tortoisesh.e.l.l box, in which they are to put the poisonous gum, and are properly instructed how to proceed while they are upon their dangerous expedition. Among other particulars, they are always told to attend to the direction of the winds; as they are to go towards the tree before the wind, so that the effluvia from the tree are always blown from them. They are told, likewise, to travel with the utmost dispatch, as that is the only method of insuring a safe return. They are afterwards sent to the house of the old priest, to which place they are commonly attended by their friends and relations. Here they generally remain some days, in expectation of a favourable breeze. During that time the ecclesiastic prepares them for their future fate by prayers and admonitions. When the hour of their departure arrives, the priest puts them on a long leather-cap, with two gla.s.ses before their eyes, which comes down as far as their breast; and also provides them with a pair of leather-gloves. They are then conducted by the priest, and their friends and relations, about two miles on their journey. Here the priest repeats his instructions, and tells them where they are to look for the tree. He shews them a hill, which they are told to ascend, and that on the other side they will find a rivulet, which they are to follow, and which will conduct them directly to the Upas. They now take leave of each other; and, amidst prayers for their success, the delinquents hasten away. The worthy old ecclesiastic has a.s.sured me, that during his residence there, for upwards of thirty years, he had dismissed above seven hundred criminals in the manner which I have described; and that scarcely two out of twenty have returned. He shewed me a catalogue of all the unhappy sufferers, with the date of their departure from his house annexed; and a list of the offences for which they had been condemned: to which was added, a list of those who had returned in safety. I afterwards saw another list of these culprits, at the jail keeper's at _Soura-Charta,_ and found that they perfectly corresponded with each other, and with the different informations which I afterwards obtained. I was present at some of these melancholy ceremonies, and desired different delinquents to bring with them some pieces of the wood, or a small branch, or some leaves of this wonderful tree. I have also given them silk cords, desiring them to measure its thickness. I never could procure move than two dry leaves that were picked up by one of them on his return; and all I could learn from him, concerning the tree itself, was, that it stood on the border of a rivulet, as described by the old priest; that it was of a middling size; that five or six young trees of the same kind stood close by it; but that no other shrub or plant could be seen near it; and that the ground was of a brownish sand, full of stones, almost impracticable for travelling, and covered with dead bodies. After many conversations with the old Malayan priest, I questioned him about the first discovery, and asked his opinion of this dangerous tree; upon which he gave me the following answer:

”We are told in our new Alcoran, that, above an hundred years ago, the country around the tree was inhabited by a people strongly addicted to the sins of Sodom and Gomorrha; when the great prophet Mahomet determined not to suffer them to lead such detestable lives any longer, he applied to G.o.d to punish them: upon which G.o.d caused this tree to grow out of the earth, which destroyed them all, and rendered the country for ever uninhabitable.”

Such was the Malayan opinion. I shall not attempt a comment; but must observe, that all the Malayans consider this tree as an holy instrument of the great prophet to punish the sins of mankind; and, therefore, to die of the poison of the Upas is generally considered among them as an honourable death. For that reason I also observed, that the delinquents, who were going to the tree, were generally dressed in their best apparel.
