I perceived that he was going to use, in my case, what was a new instrument in the practice there at that time, viz., the hypodermic syringe. "Oh, have no fear," he replied, holding up at the same time a phial of clear and colorless fluid; "this is no opium or morphia; it is one of the simplest and most harmless things in the world; but it is a secret, and no one in the town knows anything about it except myself." On this assurance, I allowed him to inject a dose into my arm. This first dose was too large, and nearly killed me or scared me to death, and I determined not to go back to him again. And I would have adhered to my determination, had he not accosted me at a hotel, about two weeks thereafter, and asked me why I had remained away; and on my telling him the reason, he entreated me to come back, saying, that as soon as he had ascertained the right dose for me, he would certainly cure me. God in heaven knows I wanted to be cured, and reasonably. I recommenced taking the injections then, and allowed him full liberty to do what he could for me. Contemporaneously with the injections, though not by prescription from this physician, but with his approval, I commenced taking carbonate of iron. This preparation of iron had been prescribed by another physician for one of my sisters, who was suffering from neuralgia, and with good results; so I thought it might probably have a beneficial effect in the case of my headache and the generally debilitated condition of my system. I took about one or two injections a week; sometimes, perhaps, I may have taken one or two more. The number was varied by the frequency or infrequency of the severer headaches. I did not go every day. I had headache every day, but only submitted to the injection when it manifested itself more severely than usual. The iron I took three times a day after meals. I thus particularly notice the iron, because it had considerable to do in forming an estimation of the results of this doctor's treatment, which I made at a certain time. I continued the hypodermical treatment, taking about the same number of injections for a couple of months, when I found myself getting better, and in a much more substantial condition of health than I had been for many a long day, or even year. I felt, indeed, better; but I observed one peculiarity in my case that was not comforting. It raised my suspicions, not having unlimited confidence in my physician. But should my suspicions turn out well founded, I argued, the great improvement in my health has justified my treatment, and I cannot see yet that I am in any danger. Let me go on a little while longer, until my health becomes permanently established, and then I will drop this doctor and his treatment. I found that the taking of my medicine had settled down into something like regularity, and when the time came around that I was restless, lacking spirit, and unable to do anything to any purpose till I had an injection.
