The first article of the sixth volume is by Mr. Winterbottom, on the use of arsenic in the intermittents of tropical climates, He finds it fucceed equally well in these, as in the . more temperate regions, except that the strength is not so foon recovered. From a short account of the weather, preceding the appearance of these diseases, we find them following the rainy season, beginning as remittents, and terminating about November and December in intermittents. The arsenic does not succeed in the night fevers from irritability, which are fo regular as often to mislead the practitioner. He adds an interesting history of the use of arsenic as a remedy; but, in encouraging larger doses, and a more general use of this drug, he is less judicious than he is in other parts of the essay.

II. · An Account of the good Effects of a Solution of Sal Ammoniac, in Vinegar, employed, as a topical Application, in Cafes of lacerated Wounds. By Mr. Henry Yates Carter, Surgeon at Kettley, near Wellington, in Shropshire.'

The application, now recommended, was hinted at in the second volume of the Medical Facts.' It is at present enforced from having been found useful in very violent lacerated wounds, compound fractures, &c.

III. Case of a diseased Kidney. By the fame.'

This is a case of nephritis, terminating in suppuration, in consequence of external bruises; but the kidney had certainly before been diseased from gravel. The cause is fingular, and the history deserves to be recorded. The violent pain, it may Þe remarked, occurred only after the suppuration.

IV. · Case of a Gun-Shot Wound of the Head. By the fame.'

A Heffian grenadier received a ball on the external canthus of the eye: it passed through the head, and came out a little • below, and behind, the opposite ear. It evidently missed the optic nerve and the frontal sinus; and, as there was the advantage of a depending drain, the inan recovered completely.

V. • An Account of some extraordinary Symptoms which were apparently connected with certain inorbid Alterations about the Veins and Nerves. By Mr. John Pearson, Surgeon of the Lock Hospital, and of the Public Dispensary.”

This is a curious paper. Many instances are recorded, in which finall indurated tumours have been attended with much pain and general nervous complaints. It seems, froin the case before us, and froin fome others, that they proceed from a portion of vein and nerve, included in the indurated tumour, which prevents any expansion at least of the former, and irriţates the latter. The iubitance of our author's explanation may be found in the following extract

? As the preceding history contains fome curious and rather uns


common cireuinstances, I beg leave to offer a few observations upon some of them. The indurated part having been destroyed by a caustic, it was not in iny power to examine its internal structure, so as to discover the true nature of the morbid alteration. I ascertained, however, that a portion of the vena saphena major, and that branch of the crural nerve which accompanies it in its course down the inGde of the leg, were completely included within this tumour. This fact was clearly demonstrated after the exfolia. tion of the eschar; for I then saw a portion of the vein hanging down at the superior part of the fore, and the naked nerve in contact with it; and on touching the nerve with my probe, Mrs. P. instantly complained of an acutely painful sensation, fimilar to that which she had been accustomed to feel before the tumour was re-. moved. I then destroyed that part of the nerve which was exposed with lunar caustic, and my patient suffered no more uneasiness, After thus proving that a vein, and a considerable ramification of a nerve, were contained within the diseased part, I proceed to observe, that the paroxysms of pain were excited by every thing that accelerated or otherwise disturbed the circulation of the blood; whether applied to the induration, or affecting the general system ; as all strong exertions of the muscles, external impulse, or mental commotion. The ascent of the blood, in the veins of the lower extremities, is neceffarily impeded in the state of pregnancy; and during this period, the fits of pain were always sharper, and were also of longer duration; and at the time of parturition, when the action of the heart and blood-vessels is considerably increased, Mrs. P. suffered exceedingly; for, to use her own expreflion, she “ had all her labour pains in her leg."

. It is also highly probable that the portion of vein which parted through the tumour was unusually diftended with blood at the time of the paroxysm; for upon these occafions, the morbid furface became redder than common; and the tumour was sensibly elevated. We may therefore, perhaps, venture to conclude, that the vein and the nerve being confined within a substance that could not be easily distended, whenever the vein became preternaturally turgid, the nerve was compressed between its parietes and the internal surface of the induration ; and that consequently the symptoms were connected with this state of the part.'

VII. A Case of Aneurism of the Crural Artery. By Mr.
Thompson Forster, Surgeon on the Staff of the Army, and
Surgeon to Guy's Hospiral.'

P. 99.

The aneurism was seated in the upper part of the thigh, almost as high up as where the profunda paffes off. The event was fortunate.

VIII. · An Account of a Key Instrument of a new Construction ; with Observations on the Principles on which it acts, in the Extraction of Teeth, and on the Mode of applying it. By Mr. Robert Clarke, Surgeon at Sunderland, in the County of Durham.'

This article is incapable of abridgment, and unintelligible without the plate, which however is not a very striking illustration of the improvement.

IX. “An Account of a new Species of Swietenia (Mahogany), and of Experiments and Obfervations on its Bark, made with a view to ascertain its Powers, and to compare them with those of Peruvian Bark, for which it is proposed as a · Subititute: being an Abstract of a Paper on this Subject, ad

dressed to the Honourable Court of Directors of the United East-India Company. By William Roxburgh, M. D.'

The account of the species of cincona (which, though concile, is correct), we should here notice, if we had not a more full description before us in another publication, which we Thall soon examine.

All the species of Swietenia are astringent, as well as all the genera of its natural order.

The remainder of the volume consists of extracts from philosophical collections,

The seventh is inore bulky than any of the former volumes ; and the extracts from the transactions of different focieties are mingled with the original communications, instead of following then.

I. - Practical Obfervations on the Treatment of acute Dir. eases; particularly those of the West Indies. By William Wright, M. D. Fellow of the Royal College of Phyficians of Edinburgh, and of the Royal Societies of London and Edinburgh ; and Physician to the Forces in the West Indies.”

These observations begin with some account of the success of cold washing in nervous fever; a Persian practice, which Chardin describes in speaking of the fever at Gomron, and of which De Hahn gave a favourable report when it was applied to the malignant remittent of Breslaw. It is said to be very useful in typhus, except where there are infarctions of the viscera, or intlammations of any internal organ. The practice in the yellow fever of hot climates is next detailed, without any considerable variation froin the accounts of the best writers. This fever, our author contends, is not a

remittent, because remittents are not infectious: but, if out recollection does not fail us, many instances of infectious re. mittents have occurred. - Some remarks on the pleurisy, peripneumony, hepatitis, and dysentery, follow.

II. · Facts relative to the Origin of intermittent Fevers. By Thomas Beddoes, M. D.'

Dr. Cullen has observed that intermittents arise from the efa fluvia of marshes ; but three cases occurred to Dr. Beddoes, in winter, where this cause was not to be discovered: Ergo, &c. Nothing can be more trifling than this reasoning. When intermittents were referred to these iniasmata, it was never maintained that this was the only cause, or that it was always to be traced.

III. Obfervations on the Nature of Corns, and the Means of removing them. By Mr. Anthony Carlisle, Surgeon to the Westminster Hospital.

The nature of the cuticle is well explained in this article ; but we do not think that the causes of corns are stated with cqual correctnets.

The modes of cure, recommended for corns, are these. They may be dissolved by caustic alkali, destroyed by a blister, or cured in the following manner. By cutting a hole in a piece of adhesive plaster, large enough for the corn to pass through, and placing others over it, till they rise above the apex of the corn, the pressure of the foot is brought to reft on the base ; and thus the swelled inflamed part is pressed out.

IV. · Some Observations relative to the Angustura Bark. By Thomas Masterman Winterbottom, M. D. Physician to the Settlement at Sierra Leone.'

Our author's abstract of his experience with the Angustura bark, in fevers, we shall transcribe.

• In several comparative trials made with the Anguftura and common Peruvian barks, in regard to their febrifuge and tonic powers, I have always found the former to be equally efficacious with the latter, and that frequently in smaller doses. In those cases, however, where it is necessary to give this medicine in substance, and in large doses, as in the remittent fever, with a view to put a stop to the return of the paroxysm, the Anguftura bark could not always be given for a sufficient time, without exciting nausea; but where this effect was not produced, I have trufted the course of a remittent fever to the Angustura with the same confidence as to the Peruvian bark, which last is usually considered as a specific for that disease. It must, however, be observed, that in the cases of fever where the Angustura bark was employed, the doses were perhaps larger than might be absolutely necessary ; but the fever of this country is usually so rapid in its progress, that if the paroxylms be not Toon put a stop to, the remislions become obscure, or

searcely perceptible, and the patient is suddenly carried off. I did not venture, therefore, to use it in smaller doses than what I had from experience found necessary to be given of the Peruvian bark; nor did I consider my patient as secure unless he had taken, duro, ing the time of a remission, as much of it as his stomach would bear.

16 Towards the decline of a fever, when debility is the chief symptom, I prefer the use of the Angustura bark, in infusion, to a farther continuance of the Peruvian bark ; this change is generally very agreeable to the patient; the infusion fits easy on the flomach, and is attended with the most beneficial effects in restoring the strength and appetite. I have also found Angustura bark very efftetual in the cure of intermittents: but as these most commonly occur among the seamen and Nova-Scotian settlers, who are not easily induced to take a disagreeable medicine for any length of time, I have been almost always obliged to substitute the arsenical solution in place of the bark. Vol. vii. P. 42.

In dysentery, diarrhea, henricrania, and fever from irritability, it appeared very useful. We have also found it, we think, a valuable tonic in the last stages of phthisis pulmonalis.

V. « An Account of a remarkable Affection of the Teftes. By Mr. Widdows Golding, Surgeon at Wallingford, in Berkshire, and Member of the Corporation of Surgeons in London.'

The affection (a swelling) of the teitis occurred in an epidemic fever, at Wallingford. In some of the cases, there was no reasonable suspicion of syphilis. No catarrh preceded; and no delirium attended or followed, though this symptom is considered by Dr. Darwin as almost essential.

VI. - Cafe of a Man who castrated himself.. By the same,'

The man, after his rash action, managed the wound him. self. It may bé supposed that he was not very dexterous ; and to remedy his aukwardness was the chief business of the surgeon.

VII. · Cases and Remarks on the external Application Charcoal ; by Mr. Williain Simmons, Meinber of the Corporation of Surgeons in London, and Surgeon to the Mancheiter Infirmary.

Charcoal is now, we believe, generally used in foul and carious ulcers ; and it is employed with advantage.

VIII. « Cafe of Pins extracted from the Breast of a Woman, after remaining there fixty, Years. By Mr. Henry Fryer, Surgeon at Stamford, in Lincolnshire. Comın unicated in a Letter to Dr. Simmons, by John Clarke, M. D. Physician in London.'
