local and other difficulties, it was not found possible to make this portion of the display so effective and complete as was intended. The Boyal visitors, however, expressed themselves pleased with what they saw. Electric sparks and shocks were provided for lady visitors, who cared to venture on the experiment.

"In the telegraph office alluded to above, in addition to the ABC, and large dial already mentioned, there were cases containing specimens of a large number of the cables which bind England, with a girdle of fire, to other lands; both the deep-sea and the shore ends of such cables being shown.

"Messages sent from the telegraph office to the electrical room were, if desired by the sender, delivered to friends at one or other of the stalls in the Bazaar, or even to any one walking about; in the latter case much to the amusement and astonishment of the recipients."

-Another novel feature of the Bazaar, was the exhibition of "Tisley's Compound Pendulum," kindly lent for the occasion by the inventor, Mr. Tisley, optician, of Brompton Boad. "We regret that, without the aid of diagrams, it is almost impossible to give anything like a clear or adequate idea of the curious and beautiful figures produced on paper, by this simple and ingenious instrument.

Cases of Ringworm treated by Oleate of Mercury. By Leonabd Cane, M.B. & B.S. Lond.

In introducing the use of Oleate of Mercury, in a clinical lecture published in the Lancet on May 25th, 1872, Mr. Marshall mentions its applicability to certain skin diseases, and the record of the following cases of ordinary ringworm (tinea circinata) treated by Oleate of Mercury may be serviceable.

Case 1.—Here there was a well-defined, slightly raised circular patch of tinea circinata on the side of the neck, about the size of a two-shilling piece. The spot was rapidly extending itself, and its edge was marked by a circle of small vesicles, situated on a slightly inflamed base. The centre presented a "branny" appearance, owing to its being covered with fine brownish scales. These scales when treated with Liquor potasses were found under the microscope to contain numerous spores and threads of fungus.

On June 3rd a few drops (about twenty) of the Oleate of Mercury (10 per cent, strength) were gently rubbed over the spot with a piece of lint. The Oleate was applied beyond the diseased patch.

On the third day the patient was again seen. The site of the patch was marked by a flat, circular, reddened spot of the same dimensions as the original. There were no vesicles, and no traces of any fungi could be found. The spot appeared to be completely cured, but as a matter of precaution it was deemed advisable to reapply the remedy. It was therefore dabbed over the surface, about five drops being used.

Since then there has been no reappearance of the disease. In this case the Oleate caused no inconvenience whatever. There was no staining of the skin, no pain after application, and the cure was rapid.

Case 2.—This was a much more severe case. The disease had been treated by various remedies—namely, by glacial and ordinary Acetic acid, by Iodine, &c,—and although these had stopped its progress for a time, it had invariably broken out afresh. When first seen the disease was extending almost round the whole of the back of the neck, from the angle of the jaw on one side to that on the other. It was also spreading very fast up into the hair, and for a distance of more than an inch the hair on the back of the head was invaded by the disease. There were also isolated patches on the chin, below the angle of the mouth, and on the upper lip. There were several scars where glacial Acetic acid, and, I believe, also strong Nitric acid, had been applied, and in one place there was a troublesome sore produced by the strong acid, which was kept up by the rubbing of the collar. The disease had existed for several months, and a second case had occurred in a house where the patient had been staying whilst the patches were on his neck. The newer spots were well marked and highly characteristic, and afforded abundance of sporules, &c. The site of the older ones was reddened by inflammation, and discoloured by the application of the various remedies mentioned.

On June 16th, after cutting off as closely as possible all the short hairs, so as to remove as much of the fungus as it was possible, I applied the Oleate of Mercury (10 per cent.) over the whole of the affected skin, gently rubbing it in with a piece of lint. About half a drachm was used altogether. The isolated patches on the face were similarly treated. Care was also taken to rub the hair above the diseased part with the Oleate. The patient was then ordered to wear a loose collar and not to wash his neck during the day. Some slight irritation followed the application, but this was trivial, and not for a moment to be compared with the pain produced by strong acids, &c. There was no staining of the skin, and, as the spots were in a prominent position on the face, this was no slight advantage.

On the 18th patient was again seen. There had been no fresh appearance of the disease, and the old spots had not extended themselves. There was still considerable redness over the old scars, and a few minute pustules produced by rubbing in the Oleate, but there were none of the small vesicles which had been so evident on the former occasion. The Oleate was reapplied over the places to ensure success.

On the tenth day after the first application the disease appeared to be completely cured. There were several pale red patches showing where it had been, whilst the spots on the face and chin had quite disappeared. The hair had begun to grow again, and showed no trace of the spores. The sore produced by the Acetic acid before he came under my notice had scabbed over, and was now nearly well. A third application was made as a precaution where the hair had been affected.

When seen a short time afterwards, the skin appeared perfectly well, and there has since been no reappearance of the

The advantages which Oleate of Mercury seems to possess over other remedies are:

1. It is a certain remedy if carefully applied.

2. It produces no staining or injury of the skin. In cases where the disease appears on the face, it is of great importance to avoid any disfigurement or staining.

3. It is painless in its application. This is not the case with the ordinary strong parasiticides, most of which produce vesication, &c.

4. It readily penetrates into the sebaceous glands, hair-follicles,

and even into the hairs themselves, the Mercury being in a state of solution in an oily medium, and it is therefore much more likely to destroy the fungus than the spirituous or aqueous solutions of Mercury, &c. This penetrating power of the Oleate may be increased by adding a small quantity of ether (one part to eight) to it.

In very sensitive skins the irritation sometimes produced by it may be avoided by using a weaker solution (5 per cent.), and by applying it with a camel's-hair brush. In slight cases this method is all that is necessary, but where the fungus has invaded the hair it is advisable to rub in the Oleate gently.— Lancet

Case of Diabetes Mellitus. Under the care of Mr. Kennedy.

Foe the following notes we are indebted to Mr. E. J. Carey, house-surgeon.

Mary G—, of Plasket, aged seventeen, who has never menstruated, came to the dispensary on Jan. 14th, 1874. Though previously healthy, for the last six weeks she had gradually become weak and inert. Her skin was harsh and dry, and her appetite voracious. There was great constipation, thirst and polyuria. She is a nervous subject, but there was no history of a fright or change of diet. The urine (sent that day week) showed much sugar by Trommer's test. She was given fifteen drops of tincture of perchloride of iron three times a day, and skim-milk ordered.

For the next fortnight she steadily got worse, and then the treatment was changed to ten drops of tincture of opium, and a week later fifteen drops, three times a day, with croton-oil pills. By this time she was so weak that she could not come to the dispensary herself. On Feb. 18th a sixth of a grain of Nitrate of Uranium, in water, was given three times a day, and gradually raised to the third of a grain. A week later she was much better. The week following, the bowels were regular, and the appetite and the quantity of urine no longer excessive; while on March 4th, and for a fortnight after, she had gone back to her usual diet, and felt nothing wrong with herself save some muscular weakness.

From March 21st to April 8th she was not seen, but then she returned with a bad cold and out of sorts again. However, though she was weak and needed change of air, the bowels were regular, the appetite defective, polyuria not noticeable, and the urine showed no sugar by Trommer'a test or by the fermentation and specific gravity test.

The following table shows the condition of the urine from March 11th:

Many may doubt if the Nitrate of Uranium had anything to do with the patient's recovery, but as some cases of rapid cure and many of permanent palliation of this disease by the use of this drug have been recorded,* it is to be hoped that practitioners of large experience will properly test its value in cases of diabetes mellitus.—Lancet.

De. GEORGE N. EPPS.

Da. Geoege N. Epps was born in 1815, but it was not until 1843 that he commenced the study of medicine. He took his diploma at the College of Surgeons in 1845, and ever since then he has been entirely engaged in practice according to the homoeopathic system. Before he took his surgical qualification he had assisted his brother, the late Dr. John Epps, in the lectures given by the latter on Chemistry, Botany, and Materia Medica. He was appointed Surgeon to the Homoeopathic Hospital in Hanover Square in 1845.
