tinctly recognisable as cow pocks, though some were undeveloped, and some had had their heads scratched off. They had appeared three or four days before with itching. On the 10th October they dried up, and a few days afterwards they went off without leaving a trace.

Shortly afterwards Dr. Schneider learnt from Dr. L. that he too had noticed some pustules on his body, which he attributed to having eaten roast goose (he had not been told that an eruption might be caused by the dose taken). All that I saw of this eruption was the remains of a scab on the scalp.

These facts led Dr. Schneider to make a more extensive trial of the prophylactic, and between the 10th and 21st October he distributed it to upwards of 300 persons. He writes, on the 21st October, that among these he saw fifteen cases where an eruption appeared between the second and seventh days.

The slightest eruption was spots (in two cases on the arms and chest), which went off the following day.

The next was vesicles (in one case of a young lady, on the left forearm; they rose the day after taking the dose, were fully developed the next day, dried up on the third day, and soon went off leaving no trace).

The next, one strongly developed pock (in three cases-in two on the lower hip, in one on the tendo-Achilles of the right leg); this went through the process of development and decline in two days.

The next, several strongly developed pocks (in two cases on the neck-in one there are still traces in the face and on the scalp), running their course in three days.

The next, small scattered pocks (in three cases only in the face and neck, in two cases here and there on the body); they lasted longer than the others, particularly their scabs.

Lastly, general eruption of pocks (in two cases, in the before named Mr. v. W., and in Lisbeth S-, æt. 7; in the latter on the 10th October the seventh day after taking the dose; pimples on the face and all over the body, pretty numerous; on the 19th October, pustules, which are now drying up. Besides evening rigor in the development period and nocturnal itching, no symptoms).

From these observations Dr. Schneider thinks himself justified in asserting that " vaccine matter in the dose of one globule of the millionth attenuation, given internally, produces in susceptible

individuals a greater or less and even a general eruption of pocks, and this it does by infection.

From this he thinks it follows undeniably (1) that the homœopathic's "nothings" produce some effect; (2) that vaccine matter taken internally causes infection, and that more frequently, and to a greater degree, than when inoculated, which only very rarely causes an eruption of secondary pocks, and (3) that, therefore, the internal administration of vaccine matter as a prophylactic is to be preferred to vaccine inoculation; all the more so as thereby the conveyance of other morbific causes is avoided, especially if we take the cowpox lymph from the cow direct.

These experiments and observations are extremely interesting; but we should like very much that Dr. Schneider had tested the efficacy of the eruption caused by the internal administration of vaccine lymph, by attempting to vaccinate those who took the lymph, and had or had not the eruption. We invite our colleagues to join with us in testing this new method of vaccination, and would advise that it be tested not only in the way Schneider advises with a dose of the 3rd dilution, but also in the manner originally promulgated by Severin, with repeated doses of the 30th dilution. Should this method turn out successful, we see many analogous cases in which the same principle may be applied, not prophylactically only, but also curatively. For those who are curious about the history of the employment in medicine of the products of contagious diseases, we would refer them to the sixth lecture in Dudgeon's Lectures. The prevalence of the cattle plague presents a fitting opportunity of trying the method both as a preventive and as a cure. It is now generally agreed by the best authorities that the cattle plague is an exanthematous fever, and the eruption is often seen very distinctly on the udders of cows labouring under the disease, in the form of vesicles not unlike ordinary cowpox. We would suggest that the lymph from these vesicles should be prepared, as Dr. Schneider advises, and administered both as a prophylactic to beasts exposed to infection, and to such as are already labouring under the disease. Should this method fail, we might try how it would do to pass the disease through the body of another animal, a sheep, pig, or dog for instance, by inoculating it with the lymph, and in the event of its taking effect, using the modified lymph so obtained for the purpose of inoculating cattle

prophylactically. At page 167 of Dudgeon's Lectures, it is mentioned that an extensive landed proprietor in Germany found that a very contagious disease among his sheep was at once cured by the administration of the 1st trituration of the morbid product of the disease to the affected sheep.

OBITUARY.

Dr. M. J. Chapman.

In the death of Dr. Chapman homoeopathy has to deplore the loss of one of her most distinguished adherents. He was not merely a physician, but a man of high classical attainments, a scholar and a poet. The essays from his pen that have from time to time appeared in this Journal, testify to his rare literary gifts and his fine practical tact. He wrote largely for some of our best literary periodicals, and published some volumes of poems and translations from ancient clinical writers. His intellect was strong and acute, and was distinguished by large comparison and individuality, so that he made extraordinary and happy hits in practice from his power of perceiving striking analogies betwixt remedy and disease which would have escaped less gifted practitioners. At the same time his extreme sanguineness and poetic temperament rendered his judgment less valuable as a consulting physician; and the ordinary attendant had, at times, to disclaim his power of carrying out practically the too hopeful view of the possibilities of medicine which Dr. Chapman was prone to entertain. Nevertheless he was a man of great and comprehensive mind, and of a considerable amount of genius. In moral qualities, of large and genial heart, a gentleman, and a man of courage; we fear his loss will not be replaced in our day.

Dr. Joseph Laurie.

No name is more familiar to the English homœopathic world than that of the subject of this notice. Dr. Laurie was one of the earliest practitioners of homoeopathy in the metropolis, and the Domestic Manuals he wrote have ever been the most popular of their class. He died quite suddenly of heart disease, in the night between the 9th and 10th of last month. His health had long been far from robust; but as his friends were not aware of his heart affection, and as he was able to go about his work with assiduity and satisfaction to his numerous patients, his sudden death was a great shock to all his friends and patients. Dr. Laurie was a painstaking author; a very successful practitioner; a warm-hearted friend, and, though of retiring habits, genial and humour-loving among those with whom he was intimate. The work by which he will be chiefly remembered is his large work on Domestic Homœopathy, which has gone through many editions. He also wrote a work entitled Elements of Homœopathic Practice of Medicine, intended for the practitioner, but which did not meet with so much success as his more popular book. Several other works, as the Parent's Guide, the abridgement of his large domestic work, besides an edition of Jahr, and a translation of Bönninghausen's Manual, we owe to his pen; and this Journal has occasionally received valuable contributions from him.
