The information on the subjects comprehended in the Title of this Publication, being scattered amidst a variety of Monthly Journals, can only be collected by the perusal of the whole of them; by which, frequent repetitions of the same articles are met with, particularly those of Foreign origin. Hence it is presumed a concentration of that know. ledge in one Work, published less frequently, and thereby less expensively, will mert fe approbation and patronage of a numerous class of readers. It is designed, therefore, to lay before the Public, every Three Months, correct, distinct, and faithful accounts of all facts and discoveries relating to Arts and Sciences generally, by giving the substance of every interesting paper or memoir which shall have appeared either in the English or Foreign Journals, and other Works, during the intermediate Periods of this Publication. The Remarks, which form a part of this Work, will be made with views of increasing its utility, by pointing out the possibility of improvement in such inventions and discoveries as may appear to admit of it; the means of extending them to other objects, besides those indicated by their authors; their resemblance to those already known; and, in general, by whatever shall appear likely to render them more beneficial and interesting to the Public. These Remarks will also comprise a Criticism or Review of the Specifications of Patents. Those persons whose anxiety for the earliest information induces them to purchase all or most of the Monthly Journals, will find this Work an useful Appendage; while to others less impatient, and indeed to every one, it will be desirable, as a complete Compendium or Epitome of Scientific and Practical Knowledge. Communications from Men of Science, on subjects suited to the nature of this Work, are respectfully solicited; and where pecuniary compensation may be acceptable, it will gladly be made. CONTENTS.
