MATHEMATICS, &c. Art. 32. Method to discover the Difference of the Earth's Diameters; proving its true Ratio to be not lefs variable than as 45 to 46, and fhorteft in its Pole's Axis 174 Miles. Elucidated with five Copper plates; with a Variety of new Tables fuited to the Subject. Likewife a Method for fixing an univerfal Standard for Weights and Measures. By Thomas Williams. 8vo. 5s. fewed. Stockdale. 1788. It is with regret that we obferve an Author employing his time and labour in contradicting what has been mathematically demonftrated; more efpecially when he does not fhew any error in the demonftration, or in the principles on which it is foupded. Sir Ifaac Newton computed the ratio of the diameters of the earth, from the principles of gravitation, to be as 2300 to 2290. The French academicians, not fatisfied with the conclufions of that great philofopher, fent geometricians to different parts of the earth, in order to make actual measurements; and they found the ratio to be as 2300 to 22893. The coincidence of this measurement with the former computation evinces the accuracy of both; efpecially when it is confidered that the French academicians would willingly have shewn Sir Ifaac's computation to have been erroneous. Mr Williams has, without any geometrical demonftration, stated the ratio to be as 46 to 45, that is, as 2300 to 2250. We fincerely lament that any perfon fhould thus mifemploy his abilities on fubjects already well underflood, while he might, perhaps, by other purfuits, render fcience a material fervice. Art. 33. The Scholar's Question-book: or, A Practical Introduction to Arithmetic; containing a great Variety of Examples in all the fundamental Rules. By Thomas Molineux. The 2d Edition. Is. 6d. bound. Lowndes. 1787. Art. 34. The Key to the Second Edition of the Scholar's Question-book ; containing all the neceffary Anfwers. By the Author, Thomas Molineux. 12mo. 6d. Lowndes. 1787. To the fchool-mafter who wishes to leffen his labours, we recommend this Second Edition, and Key. He will find it more useful than the first, which we commended in our Review for February 1782, p. 153. EDUCATION. Art. 35. The Complete Syftem of the French Language. By Nicholas Salmon. 8vo. 5 s. Boards. Elmsley. 1788. In our laft, we gave a character of Mr. Salmon as a grammarian, in our account of his Footstep to the French Language.' There is nothing in the prefent publication to induce us to change our opinion. of him. We could point out many errors in his work, but have little inclination for the unpleafing task; praife, where we can honeftly bestow it, being much more agreeable to our difpofition. It may be fufficient to inform the Reader, that the Author is a reformer of the language of the French Academy, on the one hand, and a profcriber of the rules of Bishop Lowth, as laid down in his Introduction to Grammar, on the other; while he continually gives fuch examples examples of his own writing as thofe which are inftanced in our review of his former Effay. It muft at the fame time be remarked, that there are some truly ufeful obfervations in the book; yet even of thefe the Public were in poffeflion long ago. Art. 36. A comprehenfive Grammar of the English Language, for the Ufe of Youth. By J. Rothwell, Maller of the Free-fchool at Blackrod. 12mo. 2 s. bound. Cadell. 1787. Bishop Lowth's English Grammar has given rife to many others, which are more peculiarly adapted to the ufe of fchools. Among other compilers of children's grammars, Mr. Rothwell has, by this publication, given proofs of his abilities as a teacher of the English fanguage, and we imagine his Grammar will answer the end propoled. BOTANY, &c. Art. 37. Arbuftrum Americanum: The American Grove, or an Alphabetical Catalogue of Forett Trees and Shrubs, Natives of the American United States, arranged according to the Linnæan Syftem. By Humphry Marfhal. 8vo. 3 s. fewed. Printed at Philadelphia; and fold by White in London. An error of the prefs in the first word of the title, and the abferdity of an alphabetical catalogue, arranged according to the Linnéan fyftem, gave us, at first opening the book, no great opinion of its merit: but we find that it contains fome ufeful remarks concerning the economical ufes of the trees that are natives of America. 'The generic character of Linné is tranflated, and the Author defcribes the varieties and fpecies in terms of his own. Though he has amply copied the writings of former American botanifts, yet by reducing into one view what was before fcattered through many volumes, and clearing many doubts, which, by his refidence in America, he was better enabled to effect than a foreigner, he certainly has contributed fomething toward the advancement of natural hiftory, in that part of the world. CHEMICA L. Art. 38. Method of Chemical Nomenclature, propofed by Meffrs. De Morveau, Lavoisier, Berthollet, De Fourcroy. To which is added a new Syftem of Characters adapted to the Nomenclature. By Meffrs. Haffen fratz and Adet. Tranflated from the French, and the new Chemical Names adapted to the Genius of the English Language. By James St. John, M.D. 8vo. 5s. Boards. Keariley. 1788. In reviewing the works of the French chemifts, we have frequently had opportunities of laying before our Readers abstracts of their theory, and the principles on which they have founded their doctrine. It would therefore be needlefs at prefent to recapitulate what we often faid in various parts of our Journal; efpecially as our chemical readers are, we fuppofe, already acquainted with the antiphlogiftian hypothefis; and thofe of them who are not, may refer to our account of Mr. Kirwan's Effay on Phlogiflon, in the Review for September last, p. 207. The prefent performance confifts of feveral Memoirs read in the Royal Academy of Sciences at Paris. The first is by M. Lavoifier, сл on the neceffity of bringing to perfection the Nomenclature of Chemistry. The fecond by M. de Morveau, explaining the principles of the Methodical Nomenclature. The third by M. de Fourcroy, illuftrating the Synoptical Table that accompanies it. To thefe are added two Dictionaries of Synonyms, viz. the Old, with their corresponding new names, and the New, with their corresponding old names. The utility of fymbols is fo great in explaining the doctrine of compound attractions, that they may be confidered as abfolutely neceffary. The old fymbols, as used by Bergman, are inapplicable to the antiphlogistic theory, and its nomenclature; on this account Meffrs. Haffen fratz and Adet have invented a new fyftem of fymbols applicable to the French opinions. As the antiphlogiftian hypothefis ftill wants the fupport and evidence of experimental facts, we therefore fufpect it will not last long. An explanation of the technical terms used by eminent writers is, however, highly neceffary for the tyro, and even in the prefent inftance for the adept: and as the French chemifts have adopted the terms and fymbols here explained, we think that the English reader is obliged to Dr. St. John for furnishing the intelligence in an Englith drefs. GYMNASTIC EXERCISES. Art. 39. Modern Manhood; or, the Art and Practice of English Boxing, &c. 8vo. 1s. 6d. fewed. Parfons, &c. Art. 40. The Complete Art of Boxing, according to the modern Method, &c. 8vo. 2s. Follingfby. 1788. Art. 41. The Battle-royal, or the Effects of Anticipation; with Strictures on The Odiad, an Heroic Poem*. With the Letters between Humphries and Mendoza, &c. 8vo. Is. 6d. Symonds. 1788. No. 1. of the pamphlets in this clafs, enters circumftantially into the theory and hiftory of this delightful eye-darkening, jaw-breaking, fcull-cracking amufement; and furnishes a variety of anecdotes, which cannot fail of proving acceptable to those who have a tafte for the fubject. No. 2. is of the fame character, but, perhaps, fomewhat more elaborately written. No. 3. has altogether the air of a catchpenny; it has more wit than the two former pieces, but less hiftory; that is, more froth, and lefs fubftance. POETRY. Art. 42. The Book of Pfalms illuftrated, by an improved Tranflation of the proper Pfalms, more conformable to the Hebrew Original, and a poetical Version of each agreeable thereto; with Notes critical and explanatory, in which the Prophecies of the Meffiah are particularly pointed out; being an Attempt to render the reading of the Pfalms, as a Part of Divine Service, more intelligible and inftructive. By a Layman. 8vo. 2s. Robin fons. A more intelligible and instructive method of ufing the Pfalms of David in divine fervice, than that which is at prefent adopted, is certainly very defirable: but we cannot think that the introduction See Art. 45. of the POETRY. of of this layman's verfion and imitations would be any improvement. The former is inelegant, and abounds with fingularities; the latter are fcarcely more poetical than the ancient doing into English by Meffrs. Sternhold and Hopkins. Art. 43. The Wrongs of Africa. A Poem. Part the Second. 4to. 25. Faulder. 1788. After the particular account which we gave of the first part of this poem, it may be fufficient to fay, that this fecond part breathes, no lefs ardently than the former, the true fpirit both of poetry and of humanity. Art. 44. Beaver-hunting; a modern Fable. 4to. 6d. Strachan. 1788. This poem is of the fatirical kind, and breathes a little of the fpirit of Dryden. The following lines will scarcely be difpleafing to our Readers: Immortal Efop! whofe fagacious pen "The Hunted BEAVER !"-Gorging in the east (The most vociferous cur that ever bark'd !) To rouse their zeal, and calls-" to hunt the BEAVER !" Hopeful the chace would drop the gift he wanted. No NO BEAVER, Well he knew! but fmarting ftill, One of thefe hounds, at length discovering his mistake, exclaims• This is no BEAVER which the pack pursue. Let us defift: the cafe is now too clear; Then let the pack purfue him for revenge! The caufe of every Caftor-loving cur!' This comparison of the fituation of a certain honourable gentleman with that of the Hunted Beaver, will by many be thought particularly happy; while others who are perfuaded of the good and virtuous motives which have prompted his purfuers to press him hard, will be offended at the infinuation here meant to be conveyed. As to ourselves, we pretend not to any opinion on the matter. Art. 1788. The poet feems to laugh at his fubject, as well he may, both in his verfe and his profe panegyric on the gymnaftic art of boxing.' He has, however, one couplet which deferves to be quoted for its fingular felicity of expreffion : Bold Humphries totters,-foil'd in ev'ry thwack- The title of Odiad is taken from the name of the town, the gymnafium on this occafion, Odiham, in Hampshire. Art. 46. The Country Book Club; a Poem. 4to. 2s. 6d. Lowndes. 1788. A pleafing defcription of a fequeftered village, of a reading fociety established in it, and of what ufually paffes at their meetings. We have been particularly entertained by the poet's recital of the poor, the very poor, curate's joy on the fuccefs of his printed fermon, with the favourable report of it in the Reviews. The whole is well imagined, and agreeably displayed, in a vein of easy, natural humour, properly fuited to the fimplicity of the fcene, and the cha How can a bowl be faid to blacken the sky? racters |
