In one of the papers referred to, that by the lady, it is stated that “if Dr. Storer will perform as noble service for our brothers and husbands as for ourselves, and send the two books out hand in hand, they will bring him back a rich harvest of gratitude and amendment in morals.” To attempt to do this is, I am well aware, a dangerous task. There are undoubtedly those who will deny its necessity, find fault with its execution, and perhaps impugn the motives of the writer. Such, however, was the case, in each of these respects, with my former essay, and as that met with so hearty and so general approval on the part of the profession, I am emboldened again to enter the arena, trusting again to disarm mistaken or unfriendly criticism. Be this as it may, I, for my own part, have become deeply impressed with the need of addressing a word to men; and believing in this as a duty, I wait not for others to decide the question for me. Accepting the labor in this light, I do not hesitate to repeat the language of my previous essay, and state that “the writer presents the accompanying paper neither for fame nor for reward. It has been prepared solely for the good of the community. If it be considered worthy its end, their approbation and that of the profession at large would be more grateful to the writer than any tangible and therefore trivial recompense.” Encouraged by the action of the Association, both at the sessions of 1864 and 1865, by which it showed most unmistakably its belief that researches like the present are for the advancement of science, and their publication for the welfare of the race, I intrust this book to the wheel of fate. Its manuscript has already passed through one trying ordeal with a certain measure of success. Submitted to the touchstone of the Prize Committee of the Association for the present year, it was distanced by the essays of Drs. Black of Ohio, upon the Cause of Intermittent and Remittent Fevers, and Pallen of Missouri, upon the Treatment of certain Abnormities of the Uterus, treating as these did of subjects of more direct and especial interest to the medical profession; but it elicited the following letter from the distinguished professor in the University of Maryland, who represented the committee as its chairman, and was, of course, unaware of the identity of the author, which had been carefully disguised till I wrote to reclaim the manuscript. “BALTIMORE, 21st May, 1867. “DEAR DOCTOR: “I have read your essay with very great interest, and hope that you will publish it. It certainly will do good. The subject, although one of great delicacy, is handled with marked ability. The whole profession ought to feel grateful to you for your efforts to check the fearful amount of crime in relation to abortions. Your essay will, I have no doubt, meet with the general approval of the Association. “Very respectfully, “F. DONALDSON. “DR. H. R. STOKER, Boston.”
