certain principles, theories, and even measures, which he believes to be not only repugnant to true science, but destructive of both private and social happiness—he has refrained as far as possible from personal censure;—he would much rather be engaged in the functions of an eulogist, than those of a censor. The numerous notes the Memorialist has employed—many of them, too, pretty long—will not therefore, he presumes, be objected to, on the ground of personality or supposed ill-humour. He has introduced them into his Memoirs, because he believed them to be not only useful, but peculiarly well adapted to a work of this nature, and suited to answer the general scope of its design. The author may then say, in the words of the poetical writer just mentioned—as an apology for the frequency and copiousness of the notes annexed to these Memoirs;—“I have made no allusions which I did not mean to explain. But I had something further in my intention. The notes are not always explanatory; they are of a structure rather peculiar to themselves: many of them are of a nature between an essay and an explanatory comment. There is much in a little compass, suited to the exigency of the times. I expatiated on the casual subject which presented itself; and when ancient or modern writers expressed the thoughts better than I could myself, I have given the original languages. No man has a greater contempt for the parade of quotation (as such) than I have. My design is not to quote words, but to enforce right sentiments in the manner which I think best adapted to the purpose, after much reflection.” The method of disposing of the notes, in this work, may be thought by some to impair the symmetry of the page: but so trivial a defect as this may be, in the typographical appearance of the book, will, it is supposed, be amply compensated by the convenience the reader will experience, in having the annotations, almost always, on the same pages with their respective references. In the arrangement of the Memoirs, the author has placed the incidents and circumstances relating to the Life of Dr. Rittenhouse, in their chronological order, as nearly as could be conveniently done.
