in some of the plates, unquestionably surpassed. Having said thus much in favour of the Artist, I hope I shall be excused if I add, for myself, that I have selected such specimens only as I considered likely to illustrate some of the most interesting points of the physiology of human generation, and which might assist in unravelling the various practical difficulties which beset that mysterious question;—that I have chosen those which, I believe, (with the exception of one or two preparations,) have never been published before either in this or any other country, and many of which are to be found only in some private anatomical collection;—that I have explained them in such a way as to render their meaning and usefulness evident to all my brethren;—and that, under such circumstances, I venture to believe that the plates so explained will prove of no inconsiderable service to every medical practitioner as a work of reference, where either a private or a public museum is not at hand to solve cases of doubt. I am aware that I might have extended this series of representations to more than double the present number of analogous preparations; but I purposely limited it to what it is, from a consciousness that any unnecessary increase in the number of plates, which the peculiarity of the subject did not absolutely require, would only tend to increase the bulk, and with it the expense of the “Graphic Illustrations”, without any adequate or corresponding advantage. It may, after all, be asked: were these delineations wanted? Were there not already in existence works of a similar, or at least analogous character, executed in an equally masterly style, to which the medical reader and the physiologist could refer for information and in cases of doubt? I reply, yes, to the first—and negatively, to the second question.
