Our lift of the Mathematical Pro ductions of the year commences with "Tracts on the Refolution of affected algebräic Equations, by Dr. Halley's, Mr. Raphfon's, and Sir Ifaac Newton's Methods of Approximation, publified by Francis Maferes, Efq. F. R. S. Curfitor Baron of the Exchequer." Thefe Tracts, which are ten in number, confift of a method of finding the roots of any equation generally, and that without any previous reduction, by Dr. Halley, taken from the Philofophical Tranfactions; an Appendix to the preceding, by Baron Maferes; Dr. Wallis's Solution of Colonel Titus's arithmetical Problem, with an Explanation of the difficult Pallages that occur in it, by Baron Maferes; another Solution of the fame, by Mr. Frend; Obfervations on Mr. Raphfon's Method of refolving aff-ted Equations of all Degrees by Approximation, by Baron Maferes; an Application of Simon Stevin's General Rule to extract impoffible quantities, and carefully refraining from the ufe of terms that appear abfurd or unintelligible in the folution of his problems. With respect to the propriety of that meafure, the mathematical world is much divided in opinion; but to our mind the arguments in favour of it appear more fatisfactory than thofe adduced to fupport the ancient fyftem. This part of the author's work is confined to the Doctrine of Equations; which are divided into four claffes, according to the number of their unknown terms, and are all fubjected to one general rule, viz., that none in any clafs can have more roots than it has unknown terms. In the forms of each clafs, however, the number of roots depends, partly upon the co efficients, which he denominates the co-parts, and partly upon the changes of the marks of addition or fubtraction. Mr. Frend's folutions of his problems are direct, accurate, and perfpicuous; and are followed by fome general obfervations, which convey to the learner much useful practical information. On the whole, we think that his work deferves to be recommended as a valuable elementary treatife to those inftructors who wish to teach, or to thofe young perfons who with to acquire a knowledge of, the principles of algebra, in the most easy and expeditious manner. tract one Root out of any poffible Equation in Numbers, either exactly or very nearly true, taken from Mr. Kerfey's Elements of Algebra; a Remark on an Error in the Reafoning of Clairaut, in that Part of his Elements of Algebra, in which he endeavours to prove the Rules of Multiplication laid down by Writers on Algebra concerning negative Quantities, by the Baron; a general Method of inveftigating the two, or three, first Figures of the leaft Root of an Equation, that has more than one real and affirmative Root, by the fame, and reprinted from the third Volume of the "Scriptores Logarithmici" a Specimen of Vieta's Method of refolving Algebräic Equations of any Order, or Degree, by Approximation, by the fame; and Remarks on the Number of negative and impoffible Roots in Algebraic Equations, by Mr. Frend. From tris fummary of the contents of the Tracts before us, and the well known character of the editor, the mathematical reader will be fufficiently apprifed of their value and importance. In Baron Maferes's Remark on the Error of Clairaut, he furnishes new fupport to Mr. Frend's doctrine refpecting negative numbers, in addition to what he advanced in his "Appendix to the Principles of Algebra," announced in our Regifter for the year 1798. In our Regifter for the year 1796, we introduced to our readers the first part of "the Principles of Algebra, by William Frend." We have now to announce a fecond part of that work, entitled, "the Prin. ciples of Algebra, or the true Theory of Equations established by Mathematical Demonftration." In this continuation of his plan, the author perfeveres in fimplifying the cience by rejecting negative and The "Analyfis Fluxionum, Auctore Guil. Hales, D. D. Rectore de Killeffandra, et nuper Trin. Col. Dublin. Socio, ac Linguarum Orientalium Profeffore," is divided into two parts. The first part treats of the Hiftory of Fluxions; in which the author neither awards the merit of their prior difcoyery to Newton, nor Leibnitz, but fuppofes that both thofe great men were led to the invention of the the fame principle, although differ- By Alexander Ingram, Philomath." and with other matter, critical, cioufly executed; as is, likewife, the tract which follows it, on Practical Geometry, illuftrated with plates, containing diagrams, &c. In our Register for the year 1798, we noticed the appearance of the first volume of a complete Syftem of Aftronomy, by the Rev. S. Vince, M. A. F.R.S. Piumian Profeffor of Aftronomy and Experimental Philofophy in the University of Cambridge." That truly valuable and ufeful work is now completed by the publication of a fecond volume, and entitles the author to the warm acknowledgements and commendation of every English lover of the science which it teaches. For it contains the fullest, most perfect and fatisfactory information, not only refpecting plane, but alfo phyfical aftronomy, that has yet appeared in our language. And with respect to the manner in which it is executed, the teftimony which we formerly gave to the author's merits as difplayed in the first volume, is ftrictly applicable to the proofs of them in the volume before us. The body of the work is divided into eleven chapters, in which the author fucceffively treats of the general doctrine of centripetal forces; the theory theological, and political. The From the ample title of the next work which we have to notice, our readers will receive fufficient information respecting the nature of the task which the author has undertaken. It is "the Elements of Euclid, viz. the first Six Books, with the Eleventh and Twelfth. In which the Corrections of Dr. Simplon are generally adopted, but the Errors overlooked by him are corrected, and the Obfcurities of his and other Editions explained. Alfo, fome of Euclid's Demonftrations are restored, others made fhorter and more general, and feveral useful Propofitions are added: together with Elements of Plane and Spherical Trigonometry, and a Treatife on Practical Geometry, theory of the moon; the figure of the earth; the preceffion of the equinoxes, and the nutation of the earth's axis; the denfities, quantities of matter, light and heat of the planets; the motions of the planes of the orbits of the planets, from their mutual attractions; the effects produced on the motions of the planets in the planes of their orbits, from their mutual attractions; the tides; the principles of projection, and the conftruction of geographical maps; the ufe of interpolations in aftronomy; and the hiftory of aftronomy. Thefe chapters are followed by a forcible, perfpicuous, and fatisfactory argument in favour of the existence of an intelligent, omnipotent, and infinitely good First Caufe, deduced from the fimplicity and regularity obfervable in the conftruction and procedure of the universe. To the whole the author has added numerous valuable tables, for facilitating aftronomical calculations, with precepts and examples to each; Dr. Bradley's Catalogue of 389 fixed Stars; M. de la Caille's Catalogue of 515 Zodiacal Stars, and his Catalogue of 307 principal Stars; Zach's Catalogue of 301 principal Stars, and his Catalogue of the Declination of 162 principal Stars; and Mayer's Catalogue of 992 principal Stars. To military men the following work will prove acceptable and ufeful, from the fullnefs and excellence of the inftructions contained in it, and the judicious intelligible manner in which they are conveyed. It is entitled "the firft Principles of Field Fortification: containing concife and familiar Precepts for the Conftruction, Attack, and Defence of Field Works; with preliminary Introduction to the Science of Fortification in general. By Charles Auguftus Struenfee. Translated from the German by William Nicolay, Captain-Lieutenant in the Corps of Royal Engineers." It is illuftrated with thirteen correct and well executed plates. The fecond and third parts of "a Collection of Papers on Naval Architecture, &c.," complete the fecond volume of a very useful and interefting work, which increafes in value and importance as it fwells in magnitude. The publication of the preceding divifions of this Collection was announced in our Regifters for the years 1791 and 1795. The Effavs on Gothic Architecture, by the Rev. T. Warton, Rev. J. Bentham, Captain Grofe, and the Rev. J. Milner, &c." conftitute a judicious and pleafing compilation, which furnishes the reader, at an eafy expence, with fome of the best treatifes on Gothic architecture, extracted from voluminous or coftly works, and forming together an ufeful manual on that interefting fubject. They confift of an Effay on Saxon and Norman Architecture, from Bentham's elaborate Hiftory of Ely Cathedral; Captain Grofe's Preface to his Antiquities of England; Profeflor Warton's concife Hiftory, in his Notes on Spenfer's Fairy Queen; and the Hiftory of the Origin and Progrefs of the pointed Arch, fromMr. Milner's Hiftory and Antiquities of Winchefter. They are preceded by a preface from the pen of Mr. Taylor, the editor, which displays a confiderable acquaintance with the fubjects difcuffed; and "Obfervations on the Means neceffary for further illuftrating the ecclefiaftical Architecture of the middle Ages," by the Rev. Mr. Milner. And they are illuftrated |
