imagined dogs were pursuing him. The Doctor did not know that the dog was suffering from hydrophobia, although he had feelings of suspicion, and was much interested in reading of Pasteur's inoculations.

ABSTRACTS.

HERNIA-RADICAL CURE BY INJECTIONS.—Dr. DeGarmo, in the N. Y. Medical Record, April 3, proposes the injection of from five to ten minims of the extract of white-oak bark into the injured canal for the radical cure of hernia. The injection is repeated at intervals of two weeks. He describes his method, as follows:

"The patient is first supplied with an accurately fitted truss, which shall retain the hernia as perfectly as possible; after this has been worn for about one week the first injection is made, and in the following manner: With the patient in the recumbent posture, the end of the forefinger of the right hand is passed into the external ring by invaginating the scrotal tissues, the cord and the sac being held to the outside of the finger. The forefinger of the left hand is now pressed firmly over the end of the finger that is in the ring, and, as the latter is withdrawn, the latter is pressed directly into the ring. The needle is passed at the end of the left forefinger, directly into the cord, and the fluid gradually deposited.

Slight discomfort follows the injection, which usually continues for two or three days, and the parts are sensitive for a week afterward. The truss is worn constantly, even at night, if too much discomfort is not produced.

Wyss ON THE TREATMENT OF ECZEMA BY RESORCINE.—He says: In the treatment of eczema, two questions of paramount importance at first arise.

Is the eczema acute, or chronic?
With what stage of the disease have we to deal ?

Different stages of the disease may be manifest in the same patient, and consequently the same patient may require for one part one kind of treatment, and for another, quite a different kind.

During the acute stage all active remedies must be laid aside, as doing more harm than good. Soothing powders or washes, to allay the itching, being alone admissable.

The treatment of chronic eczema requires: 1, the removal of the scales and scabs which form on the diseased places; 2, the dessication of discharging places; 3, the diminution and suppression of the infiltration, hyperæmia, and desquamation of the skin.

Dr. Wyss, while suffering from carbol-eczema of both hands, used, for the purpose of allaying the unbearable itching, an ointment of vaseline with ten per cent. of resorcine. The itching was arrested immediately after each application. The pruritis from the final desquamation was also controlled by the use of the same ointment. From this Dr. Wyss was induced to try resorcine on others. He employed it in the form of a powder with rice-meal, Venitian talc, etc.; e. g. rice-meal 20 grammes, resorcine 2 to 5 grammes. The great drawback to these powder preparations is the extreme hygroscopic properties of recorcine. He also used it in oil; e. g. resorcine i to 2 grammes, olive oil and almond-oil, of each 25 grammes; also as a solution in glycerin, 25 per cent.; and in the form of an ointment, 10 to 25 per cent. in vaseline or lard.

The following are the general effects of these remedies. The preparations of resorcine, especially the powders, when applied in eczema, during the stage of discharge, produce, in consequence of the property of resorcine to coagulate the albumen of the secretion, a protective and disinfectant covering, which, without giving rise to irritation, stimulates the formation of the epidermis, allaying, at the same time, both pain and itching. During the stage of desquamation, the ointment or the glycerin of resorcine accelerates the cicatrization of the still existing fissures of the skin. The new epidermis, stimulated by the action of resorcine, more rapidly and easily reforms, and gains its normal thickness and firmness.

Dr. Wyss recites a number of his cases, one of which will serve as an example of the use of the drug.

"A man, aged 42, suffering from chronic eczema of both lower extremities, which presented all the different stages of the complaint, had been under the author's care during twelve months previously, during which the eruption on the forehead, the body, and the upper extremities, entirely disappeared after the use of napthol ointment. The eczema of the lower extremities, however, resisted every kind of treatment. The itching was so intolerable that the patient could not refrain from frequently scratching, whereby in every instance a new crop of eczema was called forth in places where the eruption already had reached the stage of desquamation. After a month's use of resorcined vaseline, no new eruption of the eczema had taken place since, and the remnant eruptions betrayed themselves only by induration and patches of pigmentation of the skin. Having no more itching, the patient no longer irritated his skin by scratching.”

Dr. Wyss has treated, up to the close of last year, more than thirty cases of eczema with resorcine, and has invariably noted the same good results and especially the tendency to rapid healing.

The stages of eczema in which resorcine proves most beneficial are those of exudation and that of dessication where there are still some intractable discharging fissures.— The London Medical Recorå.

PILOCARPINE IN PNEUMONIA. - In the Paris letter of the Medical News it is stated that Dr. Mollière has successfully treated pneumonia with hypodermic injections of pilocarpine. In the cases cited the pneumonia was a complication of Bright's disease. The dose given was followed by profuse sweating aud salivation. “The respiratory movement fell from 48 to 24, and the dyspnea was much relieved.”

TREATMENT OF “Colds."- Dr. David B. Lees, in the Lancet, Feb. 27, advises for acute colds, first large doses of bromide of potash, from forty to sixty grains every two or three hours, and after the dry stage has passed and the secretions become free, belladonna given freely until the throat becomes dry. He says that by this means he rarely fails to cut short a cold.

MEDICAL TREATMENT OF ANEURISM. - Dr. Stone, in the Lancet, March 27, reports a case of thoracic aneurism relieved by rest in bed and fifteen grains of potassium iodide, three times daily. The patient was under treatment for three months, when the tumor had decreased in size and the subjective symptoms had about disappeared.

Sometimes the deluded victims prefer to be poisoned Sometimes they dread the dire effects of the deleterious article, yet seem to be led on, as if by siren songs, to fatal results. At other times they seem indifferent, possibly through ignorance, but oftener because the injurious results are slow in progress and not violent in their manifestations. Even when the bad influences are liable to be transmitted from generation to generation the indifference remains. Posterity poisoned? Well, who cares? What has posterity done for us?

Now the reader can understand that if a people and nation have been constantly and continuously poisoned for generations, they will learn to regard the effects of the poison as normal manifestations of life.

For want of proper ventilation all are more or less poisoned by carbonic acid, and other exhalations from living bodies.

Many are poisoned by tobacco, and the symptoms are not recognized as the legitimate effects of the drug, inasmuch as they

are mild and common. Alcoholic poisoning, whether acute or chronic, though quite familar, is often misunderstood, and the victims almost always ascribe the phenomena to other causes. Metallic poisoning is so insidious and so gradual in its effects that the victims are usually incredulous till ruined constitutions result. The printer ascribes his ills to confinement within doors, and if his peculiar pallor is referred to he suggests that the ink may account for

And so it goes, and he who sounds an alarm for the purpose of arresting the evils, is regarded as a crank or a fanatic.

But to discuss all the varieties of popular poisoning would take too much time and space, and as this is intended for a dental periodical, I shall only inquire as to the possibilities and probabilities of mercurial poisoning from the use of amalgam cements in filling teeth. This is a hackneyed and unpopular subject; but I think it has not received that attention from physicians that its importance demands.

I suppose it is safe to assume that many hundreds of pounds of mercurial pastes are used by dentists in a single year. It is probable that more attention is given to the preparation of these pastes than formerly, and it is possible that this renders the danger from poisoning less. If any such danger exists it is widely diffused, for probably one half the adult population who still retain their natural teeth have more or less of this material in their mouths. And this general diffusion makes the subject very important to physicians, who are the recognized conservators of the health of society. And bearing this in mind, I have no apology to give to dentists for taking up the subject.

It would prove tedious to notice all the symptoms of mercurial poisoning, but at the start I will notice some of its manifestations on the nervous system.

Pereira says, under the head of Neuroses Mercurialis:" "various symptoms, indicating a disordered condition of the nervous system, are met with in persons who have been exposed to the baneful influence of mercury; such as wandering pains (neuralgia mercurialis), a tremulous condition of the muscular system (tremor mercurialıs), sometimes accompanied with stammering (psellismus metallicus), and occasionally terminating in paralysis (paralysis mercurialis), epilepsy or apoplexy (apoplexia mercurialis). To these Dieterich adds asthma (asthma mercurialis), of which he saw only one case, amaurosis (amaurosis mercurialis), and hypochondriasis, (hypochondriasis mercurialis)."
