root of the third broken by a gunshot. This accident took place September 1st. Fourteen days afterwards, the wound doing well, the patient was carried from Poissy to Montmartre, where he lived. The next day, 15th, the wound became very painful; acute pains manifested themselves equally in the temporo-maxillary region of the right side. The 17th, rigidity in the muscles of the face appeared, jaws and neck (frictions with chloroform relieved them, opium and musk internally.) On the 19th, trismus more marked, sardonic expression, violent contraction of the thoracic and abdominal muscles, deglutition very difficult, asphyxia very imminent. Drs. Andre and Taër wished to employ curare, but could not procure any.

In the afternoon of the 19th, M. Chassaignac, called in consultation, found the patient in the following state: palpebral opening reduced to a simple slit, nostrils very much dilated, considerable trismus; the mouth did not admit anything but a thin piece of wood, which was left between the teeth. The muscles of the neck, chest and abdomen are extremely hard; those of the extremities equally contracted; Emprosthotonos marked, threatened asphyxia, pale face, cold extremities; wound very painful, everted edges, pouring out an abundant and very foetid suppuration; no urine for twenty-four hours, bladder not distended. R ten centigrammes woorara; mucilage, 3iijss. To take a tablespoonful every hour. The wound to be washed every two hours with a solution of 20 centigrammes of woorara in 300 grammes of distilled water, and to be covered with charpie.

The first dose of the medicine was administered at 7 p. m. When the second dose was given at 8, the patient felt better, and breathed easier, and found his jaws less contracted.

The next day, the 30th, M. Chassaignac observed, near 10 o'clock, a marked improvement. Decubitus dorsal, face colored, moistness of skin, less trismus. On the 31st, the muscles a little distended, but in places only; the trismus persisted. For the rest, the rigidity disappeared and reappeared at intervals. From this time, the dose of the woorara applied to the wound was increased to 30, and then to forty centigrammes. Towards the 24th or 25th, fearing that the very rapid cicatrization of the wound would not allow a sufficient absorption of the remedy, the internal dose was increased to 15, and then to 20 centigrammes. The two

mixtures were taken in twenty-four hours. creased, although in an unequal manner. reported, there was still some trismus.-Gazette Hebdomadaire.

2. The Value of some New Remedies lately introduced in the Treatment of Phthisis.-Dr. Botini affirms that the hypophosphites of Dr. Churchill have not even relieved a single patient. The phospholéine of M. Baud, extracted from the spinal marrow of animals, does not seem to possess any other value than as a nutritive, etc. Milk, iodized by digestive assimilation, is preferable to the most part of medicaments containing iodine or iodide of potassa. In view of this fact, Dr. Carmagnola puts forth some very just considerations, establishing clearly that there is little reason in demanding from a product of secretion, as from cow's milk, a medicine whose first action has been to alter the health of the animals, and even the nature of the milk furnished. It would be better to use the flesh of the cows, so as to have iodized soups and beefsteaks.- Gaz. Medica Italiana: L' Union Méd. de la Gironde.

3. Santonine in Nervous Amaurosis.-Dr. Gaet. Terzi states that he administered to a man 30 years of age, lymphatic, amaurotic, without any signs of ocular congestion, three grains of santonine daily during twenty-four days, dissipating little by little the mydriasis, bringing back the mobility of the iris and sensibility to light. Encouraged by this considerable improvement of his condition, the patient continued the santonine, which continued the cure. M. Terzi, remarking that santonine, from the fact of its insolubility in the acid liquids of the stomach, passes very largely into the intestines before being absorbed, proposes to substitute for it, when we wish to produce its rapid absorption and electric action on the eye, the perfectly soluble santonate of soda, while we should reserve santonine for those cases where we desire that it should pass into the intestines, so as it may destroy the ascarides lumbricoides, against which it is so often given.- Gazetta degli Ospedali (di Genova): L' Union Médicale de la Gironde.

4. Iodohydrate of Ammonia in Constitutional Syphilis.-Prof. Gamberini deduces the following conclusions from fourteen cases: 1. Iodide of ammonia and the iodobydrate of ammonia are indicated in the same cases of syphilitic diseases as the iodide of

potas; 2. The treatment from the employment of this remedy in increasing doses from 10 to 80 centigrammes daily, in from 100 to 180 grammes of some liquid, has lasted from 14 to 35 days, averaging 21 days; 3. A sensation of burning or heat in the throat and stomach of some patients forced us to suspend temporarily the iodide, as well as to lessen the dose; 4. A liniment, composed of the same remedy, with olive oil, 15 centigrammes of the former and 30 centigrammes of the latter, has assisted in curing the osteocopic pains; 5. Syphilitic accidents cured by iodide of ammonia have been cases of arthralgia, rheumatic neuralgia, periostosis, ganglionic enlargements of the groins and neck, and a papulo-vesicular eruption of the back.

The process of making this medicine is very simple. It is that of Ruspini, consisting in precipitating a solution of the iodide of iron by carbonate of ammonia, filtering the solution, which is then to be evaporated promptly, until a pellicle is formed, and then crystalize. This salt crystalizes in cubes, and is very soluble in water. Its taste is not very disagreeable, being a little more bitter than iodide of potas.--Bolletino delle Scienza Medica: L'Union Médicale de la Gironde.

A SYSTEM OF DENTAL SURGERY. BY JOHN TOMES, F.R.S., Dentist to the Dental Hospital of London, and to the Middlesex Hospital. With 207 illustrations. Philadelphia Lindsay & Blakiston.

In cities, and in villages of any considerable size, practical dentistry is made a specialty. The diseases of the teeth, and of the parts subservient to them, the preservation of the integrity and utility of the former, and the final extraction of old offenders, when their infirmities render their presence of more trouble than profit, and of more pain than pleasure, are intrusted, under such circumstances, not to physicians, but to dentists. In the country it is different. The field of the physician's usefulness and labor widens as it is removed from cities and large towns. The country physician is expected to be not only a physician, pharmaceutist, surgeon, obstetrician, oculist, but a dentist also, and it is well for

him to be prepared to do what is expected of him with satisfaction to his patients and honor to himself. There is no physician but what will find it to his advantage and credit to be thoroughly posted in dental surgery, at least sufficiently so to understand and prescribe judiciously for the diseases of the teeth, gums, etc. Who that has suffered from odontalgia, but what could appreciate all that Burns says of this "hell o' a disease," and could realize that the mitigation of such suffering was worthy the study and the curative efforts of the physician? We know of no work better adapted to the wants of the physician than the one before us. In it "the diseases of the teeth, and of the parts subservient to them, together with the coincident maladies, have been treated of, so far as may be, in the natural order of their occurrence, and the structure and development of the tissues involved have been to some extent described before entering upon the diseases to which they are respectively liable."-Author's preface.

We do not propose to enter into a review of the work before us, but simply give such brief analysis as will give our readers some idea of the character of the work.

Part First is devoted to teething, and includes development of the jaws and teeth, eruption of temporary teeth, irregularity of temporary teeth, irregularity of position of teeth, eruption of permanent teeth, and irregularities of permanent teeth. This part occupies 262 pages, with just such information as every physician should acquire, and is illustrated with 116 appropriate and well executed wood-cut engravings.

Part Second is devoted to dental tissues, and includes a description of the tissues and the diseases to which they are subject, as caries, exostosis, necrosis, absorption of permanent teeth, diseases of the pulp, acute inflammation of the pulp, chronic inflammation of the pulp, inflammation of the alveolar periosteum, absorption of the alveoli, hypertrophy of the alveolar processes, and necrosis of the alveolar processes. This part includes 282 pages, and is accompanied with 61 illustrations. Under the head of caries and its treatment, the operation of filling is considered in all its minutia of detail. An idea of all the instruments used in this department of dental surgery is imparted by illustrations. We quote a passage or two, to give an idea of the author's style. "There is perhaps no other operation performed upon the human body which

is attended with the same unqualified success as that of filling teeth, for we not only succeed, in the great majority of cases, in arresting the further progress of disease, but we also replace the part which has been lost by an imperishable material, and render the organ as useful as it was prior to its becoming the subject of caries. It is, however, a great error to suppose that filling will, under all circumstances, permanently save the tooth, even in cases which, at the time the operation is performed, promise favorably."-p. 386.

All the various substances used for the purpose of filling teeth are enumerated, and the particular uses of each, and their respective merits, are considered. "In making a selection from these forms of temporary fillings, we must be guided by the objects to be attained. Supposing the tenderness of the tooth is the barrier which precluded the adoption of a metallic plug, the mixture of chalk and varnish will be found the most durable, and also the most agreeable to the patient."—p. 402. "A new compound for filling teeth has recently been produced. A mortar is formed by mixing oxide of zinc with a solution of chloride of zinc. The compound hardens very quickly to the density of good plaster of Paris, and must be introduced into the tooth without loss of time. Although cases have occurred in my own practice in which this filling has been unaltered after the lapse of six months, it can not, with our limited experience of its durability, as yet be regarded otherwise than as a temporary remedy."-p. 404. Of gold, he says: "There are several methods of using gold foil. In one, the leaf is cut in strips, which are afterwards folded into ribands of suitable length and breadth, or twisted loosely into ropes. The riband or the rope is introduced into the cavity by an instrument having a wedge-shaped extremity, in such a manner that each fold shall have one extremity resting on the bottom of the cavity, while the other projects slightly from its orifice. When we are unable to introduce any more foil, a sharp-cutting, wedge-shaped instrument is forced into the centre of the metal, which by the act of perforating presses the gold forcibly from the centre towards the circumference of the cavity. The hole thus produced is filled by folding in vertical layers a further quantity of riband or rope. The operation of perforating and refilling is repeated until the gold becomes so dense that the instrument can not be
