man prescribed Zinc mur. 3rd, internally, and with success. By means of the remedy in this diluted form he cured in three or four weeks a military gleet that had lasted twelve years. Two other cases of shorter duration also yielded to the same remedy.

But our colleague on several occasions obtained a more rapid success in this disease by injection of the same remedy-1 decigr. of the 1st trit. of Zinc. mur. to 120 gr. of water. This solution, containing 1-12,000th part of Zinc mur. was about the strength of the 3rd trit.

These injections of infinitesimal strengths of medicine must be very efficacious, seeing that the allopaths, in spite of their horror of Hahnemann's posology, make use of them. For instance, I remember the following injection used by Dr. Rodet in chronic gonorrhoea-1 centigr. of Nit. Argent. to 120 gr. of water. This solution, equivalent to our 2nd dilution, was prescribed by Dr. Rodet in his venereal wards at the Hospice de l'Antiquaille (Lyons). And, if I am not mistaken, one of his successors in this hospice imitates his example in this respect, and probably with the same success.-Gallavardin, Art. Médical, April, 1866.

Cannabis in Gonorrhoea. BY Dr. BAIKIE.

In answer to the Queries propounded by Nemo at p. 170 of the January No. of this Journal, in regard to the Homœopathic treatment of Gonorrhoea, I may state that when in practice at Tunbridge Wells some years ago, I had occasion to treat several cases of gonorrhoea, and was almost uniformly successful in curing them within a few days by the use of Tincture of Cannabis Sativa, 1, in doses of 1 drop three times a day. I generally, at the same time, recommended rest and abstinence from stimulants of every kind.

Neuralgia. By DR. TUTHILL MASSY.

Miss L. D. æt. 32, sallow, delicate-looking, tall, and slight, took cold while standing on damp grass, on the 9th of last January, causing the period which had not quite ceased to terminate. On the evening of the following day she was quite ill with a severe pain in the right side of the head, extending down the spine as far as the last cervical vertebra, accompanied with fever furred tongue, quick pulse, &c.

Aconite 3 was prescribed. A warm hip-bath, with frictions to the spine while in it.

Next morning there was no improvement, although our patient had a good night. The fever went on increasing day by day with the pain, which would scarce allow her to raise her head from the pillow; sometimes with weight, at other times with a beating or hammering.

About the tenth or twelfth day the sympathetic fever diminished and the case became one of pure neuralgia, terminating with strabismus and diplopia. I have made no notes, nor had I any intention of putting the case on paper, until I received a very interesting communication from Dr. Mac Swinney, of Galway, on the new treatment in rheumatic and neuralgic diseases by Atropine or Morphia in solution, introduced into the cellular tissue under the skin with the syringe and puncture needle. As I have permission to publish these cases, I give the above as a contrast and introduction, for it has many points to interest the physiologist as well as the physician; viz., during the third week she invariably saw each person in the room appear double. My hand when held up before her eyes, and about from eight to eighteen inches distant, had a second or unreal hand to the right, and about two feet distant from the real hand so great was the squint in the right eye; it was drawn inward, consequently the single object or image could not fall on the corresponding points of the two retinas. This theory was clearly illustrated on the third and fourth weeks as the muscular contraction diminished in the rectus internus, and the eye reached its natural position, the false hand approached the true, and the vision became perfect on the morning of the 7th of April. Towards the evening of that day there was a slight return of the double vision from fatigue, but next day and up to the date of my writing (May 7th) she is in perfect health and much stronger than before this illness. I must not forget to mention that by closing either eye during the progress of this long suffering, vision was perfect and objects were seen natural by the single eye. I have often heard a physician who has reached a very high position say that "we see by sight and not by perception," and prolonged his argument by the laws of reflection where the angles of incidence and reflection are always equal. However, here we have an interesting fact to prove that the image having failed to strike the corresponding points in each eye, a confusion was caused by a second image, due to the want of harmony of action in both eyes. Why should this slight devia ́tion from the exact points of the nervous expansion produce such

result? If the eye had not recovered its position, would this double vision have continued, or would mental reason and eye training have educated that part of the retina which was previously unaccustomed to act in concert with the perfect eye? I have no doubt but this would have been the case, as we learn from the history of some of the successful cases of squint operation where the reverse to the above takes place.

One day I was led to test both eyes with that interesting experiment of Professor Sömmering by which images are made to vanish when brought opposite the yellow spot in the retina, or at the entrance of the optic nerve; this was done after the pain had ceased and vision was nearly restored. The results were as in ordinary eyes.* The case has led me into this line of thought and action, which, though a deviation from the treatment, is not one from the most interesting points in its character.

For the first week the case was studied systematically under the following medicines:-Pulsatilla, Belladonna, Chamomilla, Arsenicum, Bryonia, and Glonoine, without affording any real relief. I felt weary at the oft-repeated words “ no better," when shampooing occurred to my mind, and it was carefully performed by the operator, who frequently plunged his hands into hot water and carried them quietly, but firmly, over the forehead and temples, through the hair and down the back of the neck: this action was repeated frequently for about fifteen minutes, when all the pain ceased, and the patient had a good night. Towards the evening of the next day the pain returned, when Arsenicum 3 was prescribed with some slight benefit. After a day or two Quin. Sul. appeared indicated by the intermittent symptoms and debility; a grain every three hours. In truth, I gave up all hope of recovery until the period would return, which it did in due course, but without bringing with it any permanent relief. Acet. Morph. 1st trit., gr. 1, 2nda q.q. hora, was given with some benefit, together with nourishment of the very choicest kind. Claret and port were given on a few occasions without any marked results.

* For those who may have forgotten, I shall repeat the experiment. "Two black spots are made on a card about four or five inches apart. Close the right eye and fix the left eye on the right-hand spot. Move the card from and towards the eye, at a distance of from twelve to eighteen inches, until the left-hand spot vanishes, although it reappears when the points are brought nearer or removed farther off.

Lycopodium towards the end was indicated, and appeared to give much benefit; but I cannot make any brilliant remarks on any of the remedies prescribed. The case appeared to pursue its course, and was conducted through all its obstinancy to health.

Now I wonder very much if this case would have been cut short by a single injection of Atropine solution into the cellular tissue on the back of the neck, and the results would have told as well as the following cases by Dr. McSwinney:

Two Cases of Sciatica, treated by Hypodermic Injections of
Morphine. By Dr. McSWINNEY, of Galway.

CASE I.-Sciatica.-F. Long, farm-labourer, æt. 40, of a pale and anæmic appearance, was brought, lying in a cart, to my door, on the 16th of February, 1859. He was so totally helpless that several strong men were required to assist him into my surgery. Got a great wetting some days before; complained of sharp shooting pain in the region of the sciatic notch, worse by pressure, and in damp weather. Scarcely slept for several nights previously to my seeing him. Was treated with Guiacum Sulph., Iod. Kali, vesicants, &c., but without any beneficial results.

Was in a pitiable condition from pain and suffering.

I injected into the region of the sciatic nerve 15 minims of an aqueous solution of Morphine, containing half a grain of that alkaloid, and sent him home. He slept well that night, and, mirabile dictu! required no further treatment.

This was the first case treated by me on the Hypodermic plan, and I must add I was well pleased with the happy result.

I have this day met with Long's landlord, and that gentleman states he has been free ever since from sciatica.

CASE 2.-John Cohen, æt. 50, carpenter, suffered from a severe wetting during the month of July last. Stated that he had for ten days before application to me so much acute pain in the lumbar region and hips, that he could not move in the bed without great suffering; so much so that assistance was required to shift him about in it. Was unable to work for some weeks; underwent all kinds of general treatment, counter irritants, &c.

August 24th.-I injected into the cellular tissue at the back of his neck half a grain of Morphine, at 8 p.m.

25th.-Passed a good night, says he has not been so free from pain since he first lay down.

28th.-Having got a slight return, I repeated the narcotic injection.

29th.-Slept well last night, and is now quite free from uneasiness.

September 1st.-Relief complete, pains all gone. Slept well. 3rd.-Convalescent.

Two injections only were employed, the first of which gave prompt relief, the second removed the remaining pain and tenderness. He can now walk with ease, and is able to return to his work.

The dose and preparation of Morphine that I use is as follows:

Bo Acet. Morphic grana duo,

Acid Acetic, gutt. iv,

Aquæ destillat. 3ij. Solve, et

filtra per chartam.

Of this solution I charge the hypodermic injection syringe with mx, which quantity, in the first instance, should never be exceeded; mx are equivalent to 1-6th Morphine, and, as a rule, unless in cases of "delirium a potu," when the quantity may be commenced with one grain, it would be best to err on the side of caution.

Two Cases of Acute Rheumatism treated with the Subcutaneous Injection of Atropine. By Dr. McSWINNEY.

CASE 1. 1859, October.-Rev. J. O. H—, a strong, healthy man, was visited by me on 4th October, 1859. Slept in a damp bed a few days before, and was seized with shivering and had an attack of acute rheumatism; has pain in all his limbs, which are swollen and red, both the upper and lower extremities; had no sleep for several days before.

I injected the thigh with the 24th part of a grain of Atropine, which, after producing its characteristic effects in the system at large, subsequently removed all pain, so much so that in a few days afterwards he was convalescent, and required no further treatment.

CASE 2.-W. C—, æt. 60, a healthy man of temperate habits,
