ON THE PHYSIOLOGICAL FACTS IN REGARD TO ANESTHESIA. M. Simonin believes (Le Progres Medical, May 3, 1879) that of the various symptoms of etherization, three appear to predominate. By means of these symptoms, a diagnosis of the various degrees of etherization may be made, and by them the surgeon may be guided in the administration of an anæsthetic, and may obtain the full effect without risk of accident. The symptoms alluded to are, firstly, the manifestation of peripheral insensibility, markedly in the temples and cornea; secondly, the condition of the muscles of the lower jaw; thirdly, the state of the pupils, more especially in regard to their contraction, and to the relaxation of the iris. The con clusion of the author in regard to these points is that when the peripheral insensibility sets in, the patient is in a fit state for the surgeon. The patient is in no danger so long as the jaws remain closed. Lastly, the contraction of the iris is a nearly constant symptom of the surgical period of etherization, and the maintenance of the contraction shows that the anesthetized patient is not in any danger. But dilatation of the pupil should cause uneasiness, or, at any rate, should provoke the greatest attention on the part of the surgeon as to the state of his patient. Cincinnati Lancet and Clinic. A PERFECT SOLUTION OF SALICYLIC ACID. The following formula is contributed to the Louisville Medical News by J. F. Flexner. The editor dubs it the best solution of salicylic acid he has ever used. Advantage is taken of the solubility of the acid in both glycerine and a neutral salt. The salt chosen is the citrate of potash, because of its unobjectionable taste, its ready solubility in glycerine, and its lack of properties that would preclude its use in any case calling for salicylic acid: B. Salicylic acid..... Citrate of potash.. Glycerine... Simple elixir q. s. to make Oi. .zi-viii. The citrate is to be dissolved in the glycerine by the aid of a gentle heat, after which the acid is to be stirred in, and a gentle heat maintained until it is completely dissolved. On cooling, simple elixir is added to bring it up to the required measurement. The solution is then to be strained; and, when prepared with a colorless elixir, is of the color of a very pale sherry. It contains five grains of salicylic acid to the fluid drachm, and is miscible in all proportions with water without the separation of any acid. This preparation is said to be exceedingly well borne by the stomach. SALT IN DIPHTHERIA. A short time ago, Dr. Battle, in the Louisville Medical News, strongly recommended this agent as a prophylactic and cure for diphtheria. He has used nothing else in fifteen years in the treatment of croup and diphtheria, and his success is said to be wonderful. In a recent issue of the above journal, G. F. Stewart, M. D., writes that he has tried Dr. Battle's treatment with most marked success. AN EMETIC FOR INFANTS. "I beg Dr. S. W. Smith (Brit. Med. Jour.) writes: leave to record that half a teaspoonful of glycerine acts as a simple and efficient emetic for infants. Perhaps some of your readers can confirm this by future experience. CEREUS BONPLANDII IN NEURALGIA. R. E. Kunze, M. D.

Cases of neuralgia of the heart, facial neuralgia, etc., have yielded to this remedy in a most satisfactory way. Five drops every hour was the dose exhibited. A case of palpitation of the heart of twenty-five years' standing is reported cured by the same remedy in ten-drop doses four times a day. RHUS AROMATICA. A. M. Hayden, M.

He thinks it exerts a tonic influence upon the bladder, and particularly the sphincters. He cites an aggravated case cured in two weeks by ten-drop doses of the fluid extract three times a day. EARACHE, CHLOROFORM VAPOR. Dr. Morgan states that he has often promptly relieved the distressing earache of children by filling the bowl of a common new clay pipe with cotton wool, upon which he dropped a few drops of chloroform, and, inserting the stem carefully into the external canal, and adjusting his lips over the bowl, blew through the pipe, forcing the chloroform vapor upon the membrana tympani.-National Medical Review. BORACIC ACID IN SKIN DISEASES. Neuman prescribes an aqueous solution in parasitic skin diseases, an alcoholic solution in itching due to urticaria and pruritis, an ointment in all forms of eczema. It may also be dusted over a part in powder. The ointment is of the strength of ten parts in fifty; the solution, of ten to twenty parts in three hundred.-Der Practische Arzt. APOMORPHIA IN ASTHMA. One-tenth of a grain of apomorphia introduced hypodermically will relieve the orthopnoea of asthma in a surprisingly short time. Our readers should add this to their list of "remedies."-North Carolina Medical Journal. Attacks of sneezing caused by changes of temperature are said to be arrested by plugging the nostrils with cotton wool. SURGERY. NEW DRESSING FOR SUPERFICIAL INCISED WOUNDS. Some of our readers will doubtless remember a note in the last volume of the MEDICAL TIMES recommending the use of adhesive strips fitted with laces for closing incised wounds.
