During the early years of my practice of homoeopathy I was called to see a young man recently attacked with "epileptic fits." As he was going immediately to New York, with his sister, I advised them to call on the late Dr. John F. Gray, with whom I became acquainted during my first visit to New York. On reaching New York they called on Dr. Gray, and the young man remained under his treatment for several weeks. Of Dr. Gray's treatment of this patient, so far as remedies were concerned, I know only of a single remedy which he gave, which was Nitrate of silver, which I understood was given in a somewhat crude form, and not even in a low centesimal dilution. The young man, finding little or no benefit from the treatment, went to his home in Georgia, after which I received a letter stating that he had not been essentially benefited by Dr. Gray's treatment, and requesting me to prescribe for him. In response I sent him the 30th dilution of Nux vomica, which he took and soon recovered from the disease, and never had any return of the paroxysms. Dr. Gray was a low dilutionist. On the other hand, during my second or third visit to New York I called on Dr. Edward Bayard, who was a high dilutionist. I found him in poor health. He had been suffering, as he told me, for some time from a subacute irritation of the mucous membrane of the bowels, with loose passages, and some febrile excitement. He asked me to prescribe for him. After a careful inquiry as to existing symptoms I said to him, "Mercurius vivus ought to cure you." He replied that he had taken it repeatedly without the slightest effect. I asked him what dilution of this remedy he had taken. He replied that he had taken the 30th and 200th dilutions. I suggested that he should take the 3d trituration. "Why," he exclaimed, "I have not prescribed the 3d trituration of mercury for many years, and I do not know as I have any in my office." But, on looking around, he found a bottle of the second centesimal trituration; and I said to him: "That will answer. You can take a dose of that now [which he did] and repeat it three or four times between now and to-morrow night, after which take a dose of the 30th or 200th dilution of sulphur." The next time I saw him he told me that my prescription cured him promptly.
