The latter is represented by a curved cornice, the effect of which is to throw off the heavy seas, which being suddenly checked fly up, it is said, from fifty to a hundred feet above the very top of the building, and thus to prevent their striking the lantern, even when they seem entirely to enclose it. The efficacy of this construction is such, that after a storm and spring tide of unequalled violence in 1762, in which the greatest fears were entertained at Plymouth for the safety of the light-house, the only article requisite to repair it was a pot of putty, to replace some that had been washed from the lantern.
To prepare a fit base for the reception of the column, the shelving rock was cut into six steps, which were filled up with masonry, firmly dovetailed, and pinned with oaken trenails to the living stone, so that the upper course presented a level circular surface. This part of the work was attended with the greatest difficulty; the rock being accessible only at low water, and in calm weather. The building is faced with the Cornish granite, called in the country, moorstone; a material selected on account of its durability and hardness, which bids defiance to the depredations of marine animals, which have been known to do serious injury by perforating Portland stone when placed under water. The interior is built of Portland stone, which is more easily obtained in large blocks, and is less expensive in the working. It is an instructive lesson, not only to the young engineer, but to all persons, to see the diligence which Smeaton used to ascertain what kind of stone was best fitted for his purposes, and from what materials the firmest and most lasting cement could be obtained. He well knew that in novel and great undertakings no precaution can be deemed superfluous which may contribute to success; and that it is wrong to trust implicitly to common methods, even where experience has shown them to be sufficient in common cases. For the height of twelve feet from the rock the building is solid. Every course of masonry is composed of stones firmly jointed and dovetailed into each other, and secured to the course below by joggles, or solid plugs of stone, which being let into both, effectually resist the lateral pressure of the waves, which tends to push off the upper from the under course. The interior, which is accessible by a moveable ladder, consists of four rooms, one over the other, surmounted by a glass lantern, in which the lights are placed. The height from the lowest point of the foundation to the floor of the lantern is seventy feet; the height of the lantern is twenty-one feet more. The building was commenced August 3, 1756, and finished October 8, 1759; and having braved uninjured the storms of seventy-three winters, is likely long to remain a monument almost as elegant, and far more useful, than the most splendid column ever raised to commemorate imperial victories. Its erection forms an era in the history of light-houses, a subject of great importance to a maritime nation. It came perfect from the mind of the artist; and has left nothing to be added or improved. After such an example no accessible rock can be considered impracticable: and in the more recent erection of a light-house on the dangerous Bell-rock, lying off the coast of Forfarshire, between the Frith of Tay and the Frith of Forth, which is built exactly in the same manner, and almost on the same model, we see the best proof of the value of an impulse, such as was given to this subject by Smeaton.

BUFFON.
Buffon is reported to have said—and the vanity which was his predominant foible may have given some colour to the assertion—“I know but five great geniuses, Newton, Bacon, Leibnitz, Montesquieu, and myself.” Probably no author ever received from his contemporaries so many excitements to such an exhibition of presumption and self-consequence. Lewis XV. conferred upon him a title of nobility; the Empress of Russia was his correspondent; Prince Henry of Prussia addressed him in the language of the most exaggerated compliment; and his statue was set up during his life-time in the cabinet of Lewis XVI., with such an inscription as is rarely bestowed even upon the most illustrious of past ages[2]. After the lapse of half a century we may examine the personal character, and the literary merits, of this celebrated man with a more sober judgment.
The history of Buffon is singularly barren of incident. At an early age he devoted himself to those studies of natural history which have rendered his name so famous; and at eighty years old he was still labouring at the completion of the great plan to which he had dedicated his life.
George Lewis le Clerc Buffon was born at Montbar, in Burgundy, on the 7th September, 1707. His father, Benjamin le Clerc, was a man of fortune, who could afford to bestow the most careful education upon his children, and leave them unfettered in the choice of an occupation. The young Buffon had formed an acquaintance at Dijon with an Englishman of his own age, the Duke of Kingston. The tutor of this nobleman was, fortunately, an accomplished student of the physical sciences; and he gave a powerful impulse to the talents of Buffon, by leading them forward in their natural direction. Without the assistance of this judicious friend, the inclination of his mind towards honourable and useful exertion might have been suppressed by the temptations which too easily beset those who have an ample command of the goods of fortune. It was not so with Buffon. Although he succeeded, at the age of twenty-one, to the estate of his mother, which produced him an annual income of 12,000l., he devoted himself with unremitting assiduity to the acquisition of knowledge. Having travelled in Italy, and resided some little time in England, he returned to his own country, to dedicate himself to the constant labours of a man of letters. His first productions were translations of two English works of very different character—‘Hales’ Vegetable Statics,’ and ‘Newton’s Fluxions;’ and, following up the pursuits for which he exhibited his love in these translations, he carried on a series of experiments on the strength of timber, and constructed a burning mirror, in imitation of that of Archimedes.
The devotion to science which Buffon had thus manifested marked him out for an appointment which determined the course of his future life. His friend, Du Fay, who was the Intendant of the ‘Jardin du Roi’ (now called the ‘Jardin des Plantes’), on his death-bed recommended Buffon as the person best calculated to give a right direction to this establishment for the cultivation of natural history. Buffon seized upon the opportunities which this appointment afforded him of prosecuting his favourite studies, with that energetic perseverance for which he was remarkable. He saw that natural history had to be written in a manner that might render it the most attractive species of knowledge; and that philosophical views, and eloquent descriptions, might supersede the dry nomenclatures, and the loose, contradictory, and too-often fabulous narratives which resulted from the crude labours of ill-informed compilers. To carry forward his favourite object, it was necessary that the museum, over which he had now the control, should be put in order and rendered more complete. He obtained from the government considerable funds for the erection of proper buildings; and the galleries of the ‘Jardin des Plantes,’ which now hold the fine collection of mammals and birds, were raised under his superintendence. Possessing, therefore, the most complete means which Europe afforded, he applied himself to the great task of describing the animal, vegetable, and mineral kingdoms of nature. A large portion of this immense undertaking was left unperformed, although, to use his own words, he laboured fifty years at his desk; and much of what he accomplished was greatly diminished in value by his determination to see natural objects only through the clouded medium of his own theories. But, nevertheless, he has produced a work which, with all its faults, is an extraordinary monument of genius and industry, and which will long entitle him to the gratitude of mankind. “We read Buffon,” says Condorcet, “to be interested as well as instructed. He will continue to excite a useful enthusiasm for the natural sciences; and the world will long be indebted to him for the pleasures with which a young
