of the air in the production or cure of corporeal maladies have been acknowledged from the time of Hippocrates; but no man has yet sufficiently considered how far it may influence the operations of the genius, though every day affords instances of local understanding, of wits and reasoners, whose faculties are adapted to some single spot, and who, when they are removed to any other place, sink at once into silence and stupidity. I have discovered, by a long series of observations, that invention and elocution suffer great impediments from dense and impure vapours, and that the tenuity of a defecated air at a proper distance from the surface of the earth, accelerates the fancy, and sets at liberty those intellectual powers which were before shackled by too strong attraction, and unable to expand themselves under the pressure of a gross atmosphere. I have found dulness to quicken into sentiment in a thin ether, as water, though not very hot, boils in a receiver partly exhausted; and heads, in appearance empty, have teemed with notions upon rising ground, as the flaccid sides of a football would have swelled out into stiffness and extension.

For this reason I never think myself qualified to judge decisively of any man's faculties, whom I have only known in one degree of elevation; but take some opportunity of attending him from the cellar to the garret, and try upon him all the various degrees of rarefaction and condensation, tension and laxity. If he is neither vivacious aloft, nor serious below, I then consider him as hopeless; but as it seldom happens, that I do not find the temper to which the texture of his brain is fitted, I acccommodate him in time with a tube of mercury, first marking the points most favourable to his intellects, according to rules which I have long studied, and which I may, perhaps, reveal to mankind in a complete treatise of barometrical pneumatology.

Another cause of the gaiety and sprightliness of the dwellers in garrets is probably the increase of that vertiginous motion, with which we are carried round by the diurnal revolution of the earth. The power of agitation upon the spirits is well known; every man has felt his heart lightened in a rapid vehicle, or on a galloping horse; and nothing is plainer, than that he who towers to the fifth storey, is whirled through more space by every circumrotation, than another that grovels upon the ground-floor. The nations between the tropicks are known to be fiery, inconstant, inventive, and fanciful; because, living at the utmost length of the earth's diameter, they are carried about with more swiftness that those whom nature has placed nearer to the poles; and therefore, as it becomes a wise man to struggle with the inconveniencies of his country, whenever celerity and acuteness are requisite, we must actuate our languor by taking a few turns round the centre in a garret.

If you imagine that I ascribe to air and motion effects which they cannot produce, I desire you to consult your own memory, and consider whether you have never known a man acquire reputation in his garret, which, when fortune or a patron had placed him upon the first floor, he was unable to maintain; and who never recovered his former vigour of understanding, till he was restored to his original situation. That a garret will make every man a wit, I am very far from supposing; I know there are some who would continue blockheads even on the summit of the Andes, or on the peak of Teneriffe. But let not any man be considered as unimproveable till this potent remedy has been tried; for perhaps he was formed to be great only in a garret, as the joiner of Aretæus was rational in no other place but his own shop.

I think a frequent removal to various distances from the centre, so necessary to a just estimate of intellectual abilities, and consequently of so great use in education, that if I hoped that the publick could be persuaded to so extensive an experiment, I would propose, that there should be a cavern dug, and a tower erected, like those which Bacon describes in Solomon's house, for the expansion and concentration of understanding, according to the exigence of different employments, or constitutions. Perhaps some that fume away in meditations upon time and space in the tower, might compose tables of interest at a certain depth; and he that upon level ground stagnates in silence, or creeps in narrative, might, at the height of half a mile, ferment into merriment, sparkle with repartee, and froth with declamation.

Addison observes, that we may find the heat of Virgil's climate in some lines of his Georgick: so, when I read a composition, I immediately determine the height of the author's habitation. As an elaborate performance is commonly said to smell of the lamp, my commendation for a noble thought, a sprightly sally, or a bold figure, is to pronounce it fresh from the garret; an expression which would break from me upon the perusal of most of your papers, did I not believe, that you sometimes quit the garret, and ascend into the cock-loft.*

OVID.

POLITIAN, a name eminent among the restorers of

polite literature, when he published a collection of epigrams, prefixed to many of them the year of his age at which they were composed. He might design by this information, either to boast the early maturity of his genius, or to conciliate indulgence to the puerility of his perform

ances.

But, whatever was his intent, it is remarked by Scaliger, that he very little promoted his own reputation, because he fell below the promise which his first productions had given, and in the latter part of his life seldom equalled the sallies of his youth.

It is not uncommon for those who, at their first entrance into the world, were distinguished for attainments abilities, to disappoint the hopes which they had raised, and to end in neglect and obscurity that life which they began in celebrity and honour. To the long catalogue of the inconveniencies of old age, which moral and satirical writers have so copiously displayed, may be often added the loss of fame.

The advance of the human mind towards any object of laudable pursuit, may be compared to the progress of a body driven by a blow. It moves for a time with great velocity and vigour, but the force of the first impulse is perpetually decreasing, and, though it should encounter no obstacle capable of quelling it by a sudden stop, the resistance of the medium through which it passes, and the latent inequalities of the smoothest surface, will in a short time, by continued retardation, wholly overpower it. Some hindrances will be found in every road of life, but he that fixes his eyes upon any thing at a distance, necessarily loses sight of all that fills up the intermediate space, and therefore sets forward with alacrity and confidence, nor suspects a thousand obstacles by which he afterwards finds his passage embarrassed and obstructed. Some are indeed stopt at once in their career by a sudden shock of calamity, or diverted to a different direction by the cross impulse of some violent passion; but far the greater part languish by slow degrees, deviate at first into slight obliquities, and themselves scarcely perceive at what time their ardour forsook them, or when they lost sight of their original design.

Weariness and negligence are perpetually prevailing by silent encroachments, assisted by different causes, and not observed till they cannot, without great difficulty, be opposed. Labour necessarily requires pauses of ease and relaxation, and the deliciousness of ease commonly makes us unwilling to return to labour. We, perhaps, prevail upon ourselves to renew our attempts, but eagerly listen to every argument for frequent interpositions of amusement; for, when indolence has once entered upon the mind, it can scarcely be dispossessed but by such efforts as very few are willing to exert.

It is the fate of industry to be equally endangered by miscarriage and success, by confidence and despondency. He that engages in a great undertaking, with a false opinion of its facility, or too high conceptions of his own strength, is easily discouraged by the first hindrance of his advances,
