It would indeed have been a little hard, that the only single step, which leads at once to an extensive result, should have been made by a Foreigner, upon the very ground which I had undergone the drudgery of quietly raising, while he advanced rapidly and firmly, without denying his obligations to his predecessor, but very naturally, under all circumstances, without exaggerating them, or indeed very fully enumerating them. I should not have repined, even if no counterpart to his good fortune had occurred for my own advantage and assistance; but the exhilaration of a success, so unexpected, has brought me more immediately and more openly before the public, than it was previously my intention to appear, in relation to a pursuit so remote from the nature of many other duties which I am bound to fulfil. It may naturally be expected that I should make some apology, for what is generally considered as a violation of professional decorum; for presuming to appear again before the public, without absolute necessity, in any other capacity than that of a practical physician. I have indeed myself observed, on a former occasion, that the public is inclined to think, and not without something like reason, that the abilities of different individuals are pretty nearly equal; and that if any one has distinguished himself in a particular department of study, he must have bestowed so much the less time and attention on other departments: that, of course, if he excelled in more than one line, out of his profession, the natural inference would be so much the stronger: and that whether this may be fair or not, it is at least fair, that direct evidence should be produced or imagined of a devotion to medical pursuits, before medical confidence can reasonably be expected. My explanation then is, that I consider myself as having already produced to the public _more than sufficient_ “evidence” of my claim to this “medical confidence”; and that, having now acquired the right to celebrate a YEAR of JUBILEE, I think myself fully justified in endeavouring, without further regard to the strict etiquette of my profession, to obtain, while I have yet a few years more to live and to learn, whatever respect may be thought due to the discoveries, which have constituted the amusement of a few of my leisure hours.
