of fuperpofition, reckoning from below upwards, is, 1. granite; 2. fchiftus; 3. lime-flone. This rule has been found to hold good by fo many mineralogical travellers, that though it may not be abfolutely univerfal, it must be allowed to prevail very extenfively. Now, in this island, there are numerous inftances where bafaltes is fubftituted in the feries inftead of granite, and where it feems to alternate with granite as the fubftratum of other rocks. As limeftone is fometimes faid to reft immediately on granite, fo at the foot of the Wrekin, and at Liilefhall-hill, no flate is interpofed between the lime-ftone and bafaltes; fo that the analogy extends even to the exceptions.-But another feries has been obferved, which feems to connect granite by a closer tie with the operations of fubterraneous fire. In Italy, lava ftands to flate and lime-ftone in the fame relation as granite and whinflone in other countries. Whole ridges of mountains in the Venetian territory confift of folid lava, fometimes bare, fometimes retaining the fuperincumbent ftrata. -Thefe chains have a totally different form from the common conical fhape of volcanos or heaps of loofe ejected matter. They feem to afford a clear inftance of the manner in which long continuations of mountains have been elevated;-it appears highly probable, that they have not pre-exilted as bills in another ftate, but owe their elevation to the expanfive force of fire; and that the fame lava which appears in fo many places, lies alfo under all the limeftone hills, of which indeed there are evident indications.' One confequence of these obfervations is too important to be omitted. They lead us to reject the common divifion of mountains into primary and fecondary. The chains of granite, fchiftos, and lime-ftone, must be all coëval; for if the central chain of the Alps burft as a body expanded by heat from the bowels of the earth, it reared the bordering chains at the fame effort. It is by no means difficult to understand why no exuviæ of organized bodies are found in these imaginary primitive mountains. Kifing from a great depth, they threw afide the fuperficial accumulations of the ancient ocean. What was deepeft, is therefore now moft central; and what lay on the furface, now fkirts the high interior chains. Hence the ftrata reft indifferently on granite, bafaltes, or lava.-It is moreover certain, that all thefe lifting maffes, from granite to acknowledged lava, are found fqueezed up through fiflures formed in the ftrata by their own expanfion. This, and not the infiltration of water, as M. De Sauffure would perfuade us, appears to be the true origin of fuch veins of granite.' Dr. B. thinks it impoffible that fuch fiffures could be filled up by cryftallization from water; because if water can diffolve any, it is furely but a very fmall part of all the ingredients of granite; the cryftals must be fmall, on account of the fmall quantity of matter to form them, and a fucceeding folution can only yield another crop of fmall cryftals, it will not enlarge those already formed.'-He also thinks it contrary to all our experience in chemistry, to fuppofe crystals built up by fucceffive operations;' and yet we believe there are inftances of L 3 large large maffes, not indeed of granite, but of compound stone, variegated, and apparently cryftallized, filling up nearly the whole bore of wooden pipes through which water had been conveyed, and which must therefore have been formed by succesfive appofitions from fucceffive quantities of water.

Seventeen Hundred and Ninety-one: A Poem, in Imitation of the Thirteenth Satire of Juvenal. By Arthur Murphy, Efq. 4to. pp. 29. 25. Robinions. DR. R. JOHNSON's reputation, as a poet, chiefly rests on his imitations of the Third and Tenth Satires of Juvenal, in his poems entitled, London, and The Vanity of Human Wishes. The fubject fuited his genius and habit of thinking; the tone of his own moral feelings was in unifon with that of his author; and he found no difficulty in transfufing into the English language that vigour of fentiment, and that ftrength of expreffion, which he found in Juvenal. Mr. Murphy, as he informs the public in his preface to this poem, frequently urged his friend to add an imitation of the thirteenth fatire: but his anfwer always was, "I wish it was done." This deficiency (with respect to Juvenal,) is now fupplied; and in a manner which will do no difcredit to the talents of a writer, who has long held a very refpectable ftation in the republic of letters. In the original, Juvenal inveighs, with his accuftomed indignation, against the reigning vices of the times, particularly fraud and perjury; and he paints the horrors of a guilty mind, and the vengeance which, fooner or later, inevitably overtakes offenders. Thefe conceptions Mr. M. has unfolded at large, and applied to the prefent age, with lefs clofenefs and energy of expreffion, indeed, than we find in Dr. Johnfon's fatires, but with great felicity of imitation, and with no inconfiderable fhare of poetical merit. We quote a few lines as a specimen, referring the reader to the original, ver. 210.-Cedo, fi conata pereget, &c. Who but conceives a crime, with malice fraught, What What though the embryo fin, conceal'd with art, He groans, he rifes, but the conscious mind We are forry that Mr. Murphy has thought it neceffary to employ his elegant pen in fixing a ftigma on writers, who honeftly, however erroneously, exercise the native right of free inquiry. The poem would, in our opinion, have been more perfect, if nothing of this kind had been mingled with it; and which only ferves as an alloy to the pure gold of the general mafs-but Liberty, we apprehend, is not that goddefs, "heav'nly bright!" in whofe caufe the poets are, of all men, the moft willing to fuffer martyrdom. We furmife this, however, with due reverence and gratitude to the names of a Milton, an Addison, a Thomson, and a few others. ART. IV. Poems: confifting of a Tour through Parts of North and South Wales, Sonnets, Odes, and an Epifle to a Friend on Phyfiognomy, By W. Sotheby, Efq. 4to. pp 93. 5s. Crutwell, Bath. Faulder, London. 1790. IN the first of thefe poems, which is by far the longest, the author describes, in blank verfe, feveral of the moft remarkable and romantic scenes in Wales. His defcriptions are ftrong, and frequently poetical, though his language is frequently turgid. Some incidental circumstances, which are introduced in the way of epifodes, render this Tour' more interefting. The fonnets are principally occafioned by the remembrance L 4 membrance of views, which Mr. Sotheby had taken : many of them are pleafing; nor is the following felected as being fuperior to the reft. SONNET XII. Skirid! remembrance thy lov'd scene renews; Beholds around the lengthen'd landscape glow, Which, as the fun fhot up his last pale flame, Then bath'd in dew, meek evening filent came, Of the odes, that which is entitled Netley Abbey,' is the beft: it is fhort, and deserves to be quoted: I. • Soft on the wave the oars at diftance found, Breathes on the placid fea, and dies away. Along the dewy path my fteps I bend, To mufe on youth's wild dreams amid the ruins hoar. II. Within the fhelter'd center of the aisle, Beneath the ash whofe growth romantic spreads And all around a deeper darkness sheds; While through yon arch, where the thick ivy twines, Upon the molly ftone I lie reclin'd, And to a vifionary world refign'd, Call the pale spectres forth from the forgotten tombs. III. Spirits! the defolated wreck that haunt, Who frequent by the village maiden feen, When fudden fhouts at eve the wanderer daunt, With interdictions dread of boding found; Come from your viewless caves, and tread this hallow'd ground! IV. How oft, when howeward forc'd, at day's dim close, Echoing the chaunted vefper's peaceful note, Down the deep vaulted aisle in long proceffion float. V. But now; no more the gleaming forms appear, Save the low murmur of the tranquil deep: Trills to the filent heav'n a fweetly-plaintive moan. Farewell, delightful dreams, that charm'd my youth! In the deep ftillness of the midnight hour, Shall pour the lenient balm that fooths the foul to peace. The letter on phyfiognomony contains several good lines on a fubject, perhaps, not well adapted for poetry. This alludes to a circumftance recorded in Grofe's Antiquities, and ftill believed in the neighbourhood." ART. |
