MEDICAL AND PHILOSOPHICAL INTELLIGENCE.

FOR THE ECLECTIC REPERTORY.

The Editors are pleased to have it in their power to lay before their readers,

the following interesting Communication from Dr. Physick, which has just been handed to them. Had it been sooner received it would have occupied a more appropriate place in this Number.

HAVING repeatedly experienced considerable delay in the healing of wounds from ligatures applied on divided arteries remaining a long time in the sore before they could be removed, I have for many years been very desirous of avoiding such an inconvenience in the use of ligatures. With this view, the first idea that occurred was that of drawing the ligature tight on the vessel by the assistance of a double canula: unfortunately, the first patient on whom it was employed for securing the femoral artery, died of tetanus; and though I by no means believe the disease to have been occasioned by the instrument, yet the event discouraged from further trials of it.

Several years ago, recollecting how completely leather straps, spread with adhesive plaster, and applied over wounds for the purpose of keeping their sides in contact, were dissolved by the fluids discharged from the wound, it appeared to me that ligatures might be made of leather, or of some other animal substance, with which the sides of a blood-vessel could be compressed for a sufficient time to prevent hemorrhage; that such ligatures would be dissolved after a few days, and would

a be evacuated with the discharge from the cavity of the wound.

Under this impression, I requested Dr. Dorsey to try the experiment on a horse, by using a ligature of buckskin. This was found to answer every purpose, and came away in a few days.

This fact was mentioned at the time to several of my medi. cal acquaintance; and I understand that Dr. Hartshorne has lately tied up some of the arteries after amputating the thigh, with ligatures of parchment. They were found dissolved at the first dressing. Dr. Dorsey, in several operations, in which I have assisted, has used ligatures of French kid, which he finds stronger than any other leather. He has it cut into narrow strips, stretches them and peels off the coloured polished surface. No hemorrhage has taken place in any instance, and the ligatures are found dissolved at the end of two or three days.

With the view of ascertaining what animal substance would withstand the solvent power of pus for the longest time, I suggested the plan of trying different articles, by applying them over the surfaces of ulcers. Buckskin, kid, parchment, and catgut, have been tried in this way. The buckskin and kid dissolved first; then the parchment; when at the same time the catgut was but little changed. From an apprehension that in tying large blood-vessels the leather might dissolve too soon, I have requested Dr. Dorsey, to try leather impregnated with the varnish used by Mr. Bishop of this city, in making elastic catheters; in the hope that when so prepared it will be somewhat more durable. Perhaps tendon would be found to answer the purpose. Future experiments will probably place at the command of the surgeon a variety of these ligatures, which may be so selected as to remain the exact length of time he may require.

This hasty notice on the subject is given, because it is thought important that these facts should be made public without delay.

P.S. PHYSICK. Philadelphia, July 9, 1816.

FOR THE ECLECTIC REPERTORY.

A STONE was extracted from the bladder of a patient in the Pennsylvania Hospital on the 8th July, by Dr. Dorsey, which was found to have concreted round a mass of lead an inch in length and nearly half an inch in width. This singular nucleus consists of two laminæ of thick sheet lead, weighing two drachms

[ocr errors][ocr errors]

and thirty-eight grains. The patient, an intelligent man, declared himself unable to imaginc any way in which it could have reached his bladder. Its size and irregular shape would certainly render it difficult to introduce it through the urethra; and yet scarcely a doubt can exist that it originally entered by that passage. The stone was soft and not unusually large.

Upas Tree. The following extract from the Diary of an intelligent fellow-citizen will

be read with interest, as the accuracy of the relation may be relied on; and it is only by actual and unprejudiced observation, that the true nature of this wonderful production will be rightly understood.

In the morning we rode out to see the Upas Tree, with the sap of which the Malays poison their weapons. It is about three miles from the town of Balawangie or Balemboang, on the south-east end of the island of Java, and is much loftier than the tallest Lombardy poplar; the branches begin to grow from the trunk like the palm tree, at a considerable distance from the ground. I had an opportunity of proving, by ocular demonstration, that the accounts which we have had of its destroying the vegetation and killing any birds that may fly over it, are totally without foundation. I was myself under the tree a considerable time, rubbed my hand over the trunk, and saw birds fly on and off without any injury. The vegetation around it is remarkably luxuriant, extending to the very root of the tree.

The poison is extracted by making an incision in the trunk and catching the sap in a bamboo, and that it is deadly in the extreme I had an opportunity of proving. A bamboo, sharpened into the size and shape of the blade of a small penknife, was dipped in the sap and stuck in the leg of a dog, tied by a long string to a tree; in five minutes he began to be very much agitated; in ten he was in strong convulsions; in sixteen he

a

was raving mad, frothed at the mouth, and appeared in the greatest agony; this lasted about five minutes, when he sunk down exhausted: he lay a few moments apparently dead, when he again sprung up raving mad, foaming at the mouth for a minute or two, when he gave a yell and expired.

The tree was covered with numerous incisions, where the Javanese had been extracting the poison. There are but two of these trees on the island, one about one hundred miles from Batavia, and the one above mentioned. There are two kinds of the Upas Poison; the one, it is said, only affects quadrupeds and does not injure fowls of any kind, and the other vice versa.
