This Mr. S. accounts for in a very extraordinary manner, confidering the affertion he had just made. "It is probable," he fays, that both kinds of air might contain fome accidental "humidity, which uniting, after the inflammation, with the "water that is effential to the compofition of the empyreal air, might add a little to the weight of the product." How very fingular, that this accidental little humidity fhould, at all times, without any exception, together with the humidity supposed by Mr. S. to be contained in the empyreal air, form a quantity of water which correfponds exactly to the weight of the airs burnt! Mr. S. next tells us, that he confiders empyreal air as a compound of "an univerfal, unelastic, faline bafis" (principium falinum)" and of a certain proportion of water, and that heat "and light are nothing else than fo many combinations of this "faline principle." But it is impoffible for us to follow thefe conjectures any further. What we have faid is fufficient to fhow the nature of the effay. No. XX. is a continuation of the fame fubject. XIII.

By Mr. Sage. Mr. S. judges the Corinthian copper of the ancients to have been a brass obtained from a peculiar ore, fince the art of making that metallic mixture was not known to them. He examines a real ore of brafs, found in the neighbourhood of Pisa, which yields a beautiful brass. And he concludes with obferving, that fuch copper as partakes most of the colour of gold contains only one fixth part of zinc. XVII. On XVII.

XXVI. Some Remarks concerning the Acid of Arfenic. By Mr. Wiegleb. In the year 1783, Mr. W. obtained nine drams of arfenical acid from eight drams of arfenic, which greatly furprifed him, as both Scheele and Bergmann had afferted, that the weight of the acid was lefs than that of arfenic employed. When Mr. Lavoifier publifhed his theory, he (Mr. W.) again repeated the experiments, and conftantly found the acid to weigh more than the arfenic employed. He does not admit, however, of Mr. L's explanation, but confiders phlogiston as the cause of levity; and that, when a body is deprived of it, therefore, (i. e. when one body is detracted from another) it is heavier!

We shall here terminate, for the prefent, our curfory account of this useful publication; prepared to resume it when the editors fhall give us the occafion. ART. X. Poems, by Lady Manners. 4to. il. Is. Bell. THE lady to whom we are indebted for this volume, which, like herfelf, is no lefs beautiful in its form and appearance, than pleafing and eftimable from its higher qualities, we underftand to be the wife of Sir William Manners. The accomplished females of the prefent period have contributed very much to adorn and extend the ftores of English poetry: and, perhaps, it is but mere justice to say, that the claims of Lady Manners to the praise of harmony of verfe, and purity of fentiment, are not exceeded by those of any among her fair cotemporaries. If thefe poems are not remarkable for fire of conception and energy of thought, they are every where chafte, elegant, and sweet. The tale of Albert and Cecilia, with which the volume commences, has much genuine pathos; and the following lines, which we select as worthy to stand high among our extracts of this kind, require not any studied commendations: "ON LEAVING STEEPHILL. "AUGUST 1790. "Ye towering hills, whofe front fublime "Ye trees, that to the balmy gale, Low murmuring, bow your verdant heads! "Ye ftreams, that through the meadow ftray, Or, fparkling, urge your rapid way O'er rocks with bending ofiers crown'd! * If we may judge from the print prefixed. + Sir William is the fon of Mr. and Lady Louifa Manners, and has lately been made a baronet. "Ye "Ye whitening cliffs, that o'er the main, Whofe dangers to elude, in vain Too oft the trembling failor tries! "Each varied scene, whose native charms "And thou, romantic, ftraw-roof'd cot, The happy hours I've paffed in thee! "Where Hofpitality prefides, And pours from Plenty's copious horn! And feftive Mirth gilds every morn. Ah me! I muft no more delay; We cannot dismiss this performance without remarking, that the paper, type, and execution of the whole are equal to any thing of the kind we ever beheld, and are very highly creditable to the taste and fkill of Mr. Bell. A beautiful print of Lady Manners is prefixed to the work, engraved from a miniature by Cofway. ART. XI. The Loves of Cámarúpa and Cámalatà, an ancient Indian Tale. Elucidating the Cuftoms and Manners of the Orientals. In a Series of Adventures of Rajah Cámarúpa, and his Companions. Tranflated from the Perfian, by William Franklin, Lieutenant on the Honourable the East India Company's Bengal Eftablishment. Crown 8vo. 3s. 6d. Cadell. THE author of this entertaining volume has before obliged the public, and we eagerly embrace this our firft opportunity of rendering due praife to his merit. To the ardour and en terprise of his profeffion, he unites the elegant tafte of a scholar and accomplished gentleman; and the fatisfaction which we Y 3 feel feel from the perufal of what he has already published, is confiderably enlivened by the hope of much future gratification. Mr. Franklin informs us in his preface, that the tale here prefented to the public is held in great eftimation by those natives of India who have perufed the original. He adds, which is of no inconfiderable importance, that he was induced to engage in this tranflation, by the recommendation of Sir Wm. Jones, to whom the volume is infcribed. The outline of the tale is this:-Cámarúpa was the son of a Rajah of Oude in the empire of Hindoftan.* He occasionally withdrew from the pleafures of the court, with fix favourite companions, to follow the purfuits of the chace. In one of thefe intervals he had a remarkable dream, in which he beheld and became enamoured of the Princess Cámalatà,† daughter of the fovereign of Serendib. When he awaked, his mind was fo agitated by paffion, and averfe to all confolation, that, with the confent of the prince, his father, and accompanied by his fix friends, he commences his travels in pursuit of his mistress; of whofe exiftence he had already been affured, by some wise men of his father's court. The party, on their journey, are all difperfed by a dreadful tempeft, and engage in a great variety of adventures, which are feverally related with all the warmth and colouring of Oriental fiction. The Princess Cámalatà, it seems, about the fame period, had beheld a vifion, correfponding in all its circumstances with that of Cámarúpa. Her paffion was alike inftantaneous and violent, and much alfo did the undergo from her invariable attachment to her unknown lover. The denouement may be easily imagined. After many hairbreadth efcapes, and with the interpofition of innumerable genii, and all-powerful fairies, the youthful pair are brought together, and united in the bands of wedlock. Various epifodes are, of courfe, introduced, neither inartificially, nor without their portion of interest. After this fhort, but, we truft, fufficient analyfis, little remains for us but a few fubfequent remarks, obviously occurring from a perufal of the work. Before we came to the notes, which are added at the end, we were forcibly impreffed with the refemblance which this ftory bears in its ftructure and general ftyle of incident, to that of Sinbad, the failor, in the Arabian Nights. Indeed, if the work had been ushered into the world under the fanction of names lefs known and refpectable, we fhould have been inclined to reject it on that account, as a vile and audacious plagiarifm. This refemblance, however, is thus explained by Mr. Franklin: * Sir William Jones always writes the word Hindustan. + There is a wonderful variety in the names of this princess, pro ducing fome confufion, "That |
