Such are the facts, from which the Reporter infers, that the aneurism consisted of a protrusion of the internal and middle coats of the artery. The reasoning, founded on them, appears to us inconclusive; but we have not space to insert it, and must refer to the March No. of Le Propagateur des Sci. Med.

54. Extirpation of the Two Dental Arches, affected with Osteo-sarcoma.—Dr. Giorgi Regnoli, physician at Pesaro, performed this operation on a female 35 years of age, who had from infancy, been troubled with pain and diseases of the teeth and jaws. When Dr. R. visited her, both dental arches were enormously swelled; red and sanguineous tumours had formed over their whole surface, and covered the teeth. The alveolar processes were entirely softened. The diameters of the mouth were greatly lessened; but by the touch, it was evident, that the disease was confined to the alveolar processes of the two ossa maxillaria. A fœtid odour exhaled from the mouth. Lancinating pains continually tormented the patient; especially on attempting to masticate. The slightest touch was very painful, and was always followed by an effusion of blood. There was also an alteration of voice; a disgusting deformity of the mouth, with emaciation, fever, &c. The operation was performed on the 18th May, 1825.

The patient was seated opposite to a window; her head being supported against the breast of an assistant, who, at the same time, pressed upon the labial arteries. The inferior lip was divided perpendicularly, and detached laterally from the inferior jaw, so as to expose the whole extent of the carcinoma. Some strokes of the saw were made on the anterior and most prominent part of the bone, and into the groove thus formed, the blade of a very strong knife was inserted, by means of which, aided by some slight strokes with a mallet, all the diseased portion was removed. The soft parts had been previously detached from the internal surface of the jaw. The last left molar tooth, not being diseased, was alone left. The hæmorrhage from the dental artery was arrested by the actual cautery.

The dental arch of the upper jaw, was then completely removed in the same manner. The bleeding was here more profuse, but was arrested by a hot iron. The alveolar processes thus removed, were enlarged, and of a lardaceous colour, and the fungous growths had the appearance and consistence of indurated albumen.

In 25 days, the patient was discharged well. Her general health was good; the fœtor had quite gone; the cicatrix over the bone was regular, white, hard, and could be pressed upon without causing pain. The patient can triturate her food with facility; the lips are slightly drawn inwards, without any sensible inconvenience; and the voice is a little altered, but this even is daily improving.—Le Propagateur des Sci. Med. for Jan. 1826.

55. Traumatic Erysipelas.—In the Feb. No. of the Revue Medicale, is a clinical report of the celebrated Baron Larrey, surgeon in chief of the Hospital de la Garde Royale; in which he criticises severely the use of leeches in erysipelas, and recommends in that variety of the disease, arising from wounds, &c. the application of the actual cautery, as effectual in arresting immediately the progress of the disease. It causes, he says, but little pain; destroys the burning and tense pain of the disease, as also the redness and swelling of the part; is not followed by suppuration, and does not cause gangrene in the contiguous parts. The eschar separates, without leaving a cicatrix. Various other advantages are enumerated, all of which are confirmed by a list of cases, as treated at the hospital. We have no room for details, which would, if known universally, hardly render us Americans, whether surgeons or patients, as fond of the cautery, as our trans-atlantic brethren of the French school.

56. Obliteration of a portion of the Urethra, remedied by an operation.—M. Vanier of Cherbourgh, relates in the Jan. No. of "Le Propagateur des Sciences Medicales," the case of a man aged 27 years, who, on the 16th of June, 1815, was wounded in the penis by a musket ball, which completely divided the urethra at its middle portion, without injuring the corpora cavernosa. The wound healed up; but by degrees, the passage contracted, so that in May, 1819, the patient could pass his urine only guttatim, with pain and difficulty, and was threatened with inflammation, &c. of the perineum. Bougies afforded no relief. An incision was then made externally, in the direction of the urethra, so as to divide the cicatrix, and open the canal above and below the contracted part. The lips of the incision were drawn together over a sound, passed into the bladder; and by the 5th day, the wound was completely cicatrized. The sound was then removed, and a short bougie inserted, so as to pass beyond the cicatrix. This was worn occasionally, and the patient completely recovered. At the end of three years, he was able to "urinate with ease, and in a full stream."

57. Artificial Joint cured by Caustic.—Dr. J. Rhea Barton, has applied the caustic potash to the extremities of the fragments of a broken tibia, after an artificial joint had fully formed. Exfoliation was produced, followed by bony union. In three months, the patient recovered.

Dr. B. alludes to other cases, by Mr. White of Manchester, and Mr. Henry Cline, thus treated with success; to two instances, in which the practice failed in the hands of Mr. Earle; and finally, to one case by Mr. A. Cooper, the result of which he has not learnt. He does not recommend the operation, as usually preferable to the seton, for which, the profession is indebted to Dr. Physick; but as an additional expedient, when other means fail.—Med. Record. April, 1826.

58. Epilepsy cured by Trephining.—In the 17th No. of the New-York Medical and Physical Journal, Dr. David L. Rogers relates an interesting case of a man, aged 46, who had been subject to epileptic convulsions for 14 years, and who, of late years, had been unable to labour, and rapidly sinking into a state of idiocy, from their frequent recurrence.
