of machines and apparatus for effecting almost every kind of purpose, which are given in this work, have a minuteness of detail, and a degree of accuracy in the drawing and engraving, which are without a parallel in any work extant: the articles referring to these plates, have in general the merit, of having been written by persons, either extensively engaged in the art or manufacture treated of, or else they have been written by scientific persons, who have, with few exceptions, qualified themselves for the task, by minute investigations and inquiries, carried on in the most extensive of the laboratories, work-shops, manufactories, and public works, which so distinguish our country, by consulting original works, and by researches in the learned transactions and scientific journals, for records of the origin of inventions and improvements, and of the progress and proceedings relating thereto; in the furnishing of which materials, the writer is glad to perceive, that the "Philosophical Magazine" has held a distinguished place in the estimation of numbers of the Cyclopædia writers. With respect to most of the other branches of art, and the useful or curious applications of science and literature, the articles thereon, have mostly been written by men, eminent in their several professions, or paths of study, as will be perceived by perusing the following list, which we have prepared, from the acknowledgments made by Dr. Rees, in the preface to the first volume, compared with the announcement of his contributors' names, which were printed on the covers of parts 8 to 28, inclusive, with a few additions, which have happened to fall within the writer's knowledge or inquiries.

a It would be an act of injustice in the writer, were we to omit mentioning, the large share which Mr. Wilson Lowry has had, in procuring the assistance of able scientific men, as contributors to this work; seeing, that Dr. Rees, in his preface, has wholly omitted to mention this distinguished artist!

We could have wished to have been able to distinguish, in each case in the above List, whether various Articles, appertaining to the Science or Subject mentioned, or only the particular Article bearing the Name of the Science or Subject, are the production of the Individual mentioned; this, however, we are unable to do. Besides the above names, the Covers above mentioned, announced, that the assistance of C. R. Aikin, John Clennel, E. Coleman, Astley Cooper, Rev. W. Crowe, John Leslie, Dr. Richard Pearson, W. Symonds, and William Thomas, were engaged; but whether all, or any of these Gentlemen furnished any Articles, we are uninformed.

We have been sorry to observe, the Date 1819 affixed to the Title-page of each of the 39 Volumes, instead of that particular Year, in which each Volume was finished; because of the great number of discoveries and improvements in the useful Arts and the Sciences, which have been, for the first time, submitted to the Public, or at least in so methodized a form, in the Volumes of this Work, by the many able, practical, and scientific Individuals, who have written Articles in them; the want of these Dates to the Volumes, can scarcely fail to be the source of much literary injustice, and of high regret by the future historians of Scientific Improvement. We trust therefore, that our Readers will approve our giving here, a List containing the Dates of Publication, of each of the 85 Parts of this extensive Work; and to which we have affixed the name of the last Article in each year.

To have expected that a Work so extensive as the present, and so long in course of publication, could have been of equal Merit throughout all its parts and departments, or without several Faults, would perhaps be deemed unreasonable: suffice it to say, that its merits are conspicuous, and well understood, as its very extensive sale and patronage, have already evinced. The printing has been executed by Andrew Strahan, in an elegant style, but whose omission of pages has been complained of by great numbers, as precluding reference to particular passages in the long Articles.

ART. II.—The Jacobite Relics of Scotland, being the Songs, Airs, and Legends, of the Adherents to the House of Stuart. Collected and illustrated by JAMES HOGG, Author of the Queen's Wake, &c. &c. 8vo. pp. 444. Edinburgh, 1819.

WE gather, from some remarks in the Introduction to this volume, that the undertaking was suggested at a meeting of the Highland Society of London, to which it is dedicated. Nothing can be more praiseworthy than the purpose of rescuing from the oblivion, to which they were hurrying swiftly, the monuments raised by the poetical genius of our countrymen who had devoted themselves to the exiled family; and he must either be a squeamish politician, or a cold admirer of song, who can suffer the pernicious and absurd principles consecrated in those effusions of the Jacobite muse, to interfere with the wish common to every good Scotchman, that the literary merits of his country, in all ages, should meet with their full share of praise. At the same time, it cannot be denied, that the language held upon this subject by many persons among us in the present times, is peculiarly reprehensible. The controversy between the two families and their partisans is wholly laid at rest, by the course of nature, indeed, as well as of political events; and
