"Here oft her LORD surveys the rude domain, Fair arts of Greece triumphant in his train; 195 LO! as he steps, the column'd pile ascends, The blue roof closes, or the crescent bends; New woods aspiring clothe their hills with green, Smooth slope the lawns, the grey rock peeps between; Relenting Nature gives her hand to Taste, 200 And Health and Beauty crown the laughing waste. [_Here oft her Lord_. l. 193. Alluding to the magnificent and beautiful crescent, and superb stables lately erected at Buxton for the accomodation of the company by the Duke of Devonshire; and to the plantations with which he has decorated the surrounding mountains.] VI. "NYMPHS! YOUR bright squadrons watch with chemic eyes The cold-elastic vapours, as they rise; With playful force arrest them as they pass, And to _pure_ AIR betroth the _flaming_ GAS. 205 Round their translucent forms at once they fling Their rapturous arms, with silver bosoms cling; In fleecy clouds their fluttering wings extend, Or from the skies in lucid showers descend; Whence rills and rivers owe their secret birth, 210 And Ocean's hundred arms infold the earth. [_And to pure air_. l. 204. Until very lately water was esteemed a simple element, nor are all the most celebrated chemists of Europe yet converts to the new opinion of its decomposition. Mr. Lavoisier and others of the French school have most ingeniously endeavoured to shew that water consists of pure air, called by them oxygene, and of inflammable air, called hydrogene, with as much of the matter of heat, or calorique, as is necessary to preserve them in the form of gas. Gas is distinguished from steam by its preserving its elasticity under the pressure of the atmosphere, and in the greatest degrees of cold yet known. The history of the progress of this great discovery is detailed in the Memoires of the Royal Academy for 1781, and the experimental proofs of it are delivered in Lavoisier's Elements of Chemistry. The results of which are that water consists of eighty-five parts by weight of oxygene, and fifteen parts by weight of hydrogene, with a sufficient quantity of Calorique. Not only numerous chemical phenomena, but many atmospherical and vegetable facts receive clear and beautiful elucidation from this important analysis. In the atmosphere inflammable air is probably perpetually uniting with vital air and producing moisture which descends in dews and showers, while the growth of vegetables by the assistance of light is perpetually again decomposing the water they imbibe from the earth, and while they retain the inflammable air for the formation of oils, wax, honey, resin, &c. they give up the vital air to replenish the atmosphere.]
