habitual views. But a work of the ages cannot be hindered by individual feeling. A hundred years hence women will not be what they are now. The growing perplexity of the conscientious student awakening to the uncertainty of the art of medicine is now apparent in letters written at this time. _November 20, 1850._ DEAR E.,—I want to talk to you seriously about the future—that is to say, my _medical future_. It has been a heavy, perplexing subject to me on what system I should practise, for the old one appeared to me wrong, and I have even thought every heresy better; but since I have been looking into these heresies a little more closely I feel as dissatisfied with them as with the old one. We hear of such wonderful cures continually being wrought by this and the other thing, that we forget on how small a number the novelty has been exercised, and the failures are never mentioned; but on the same principle, I am convinced that if the old system were the heresy, and the heresy the established custom, we should hear the same wonders related of the drugs. Neither hydropathy nor mesmerism are what their enthusiastic votaries imagine them to be. At Gräfenberg I could not hear of one case of perfect cure, and unfortunately the undoubtedly great resources of cold water are not so developed and classified as to enable a young practitioner to introduce it, professedly, into his practice. Mesmerism has not converted me since watching its effects on patients. I do wish most heartily that I could discover more of the remedial agency of magnetism, for my conviction is that it ought to be powerfully beneficial in some cases; and as I find they have a magnetic dispensary here in London, I shall certainly try and attend it frequently. I am sorry that I have been unable hitherto to attend more to homœopathy, the third heresy of the present time, but I am trying now to find out opportunities. Here I have been following now with earnest attention, for a few weeks, the practice of a very large London hospital, and I find the majority of patients do get well; so I have come to this conclusion—that I must begin with a practice which is an old-established custom, which has really more expressed science than any other system; but nevertheless, as it dissatisfies me heartily, I shall commence as soon as possible building up a hospital in which I can experiment; and the very instant I feel _sure_ of any improvement I shall adopt it in my practice, in spite of a whole legion of opponents. Now E., future partner, what say you—is it not the only rational course? If I were rich I would not begin private practice, but would only experiment; as, however, I am poor, I have no choice.
