But if persons of rank and respectability choose to take an airing on their own legs, instead of an equestrian exhibition, for the _amusement_ of the public, there is no necessity that they should be of equal size and weight. Every individual must be the best judge of his own muscular powers; and if the duke of Lumber should think proper to challenge my lord Lath, to run four times round the canal in St. James’s Park, for 10,000l. the contrast in their figure would only render the diversion more entertaining to the admiring spectators. As the ladies have ever been emulous to distinguish themselves, and their proficiency in dancing is an excellent preparative to running, we may soon hope to see them exhibit themselves in the gymnastic lists, as candidates for that public admiration which seems to be the great business of their lives. The disparity between the competitors will doubtless be very amusing, as well as edifying.--When we behold the fat duchess of ----, with a face like Cynthia in all her glory, boldly approach the promenade in Kensington Gardens, in open defiance of public decorum, and, unzoned and divested of superfluous drapery, prepare for the race, in opposition to a slim vestal from ------, how shall we be able to restrain our risibility? The running ladies will, however, labour under one great disadvantage. Their muscular exertions must affect the lungs, and, in a great degree, suspend the exercise of their blandiloquence, not only during the race, but for some minutes after its termination. On a general view of the national utility resulting from this modern amusement, it appears admirably well calculated for the exercise of the legs of our nobility, gentry, and merchants, and may operate as an efficacious remedy for indolence, _alias_ laziness. It will also be conducive to the benefit of those ingenious individuals who devote their talents to the fabrication of ornaments; and we may soon expect to see, in the advertisements of mantuamakers, milliners, hosiers, and tailors, a list of _patent bounding corsets_, _Atalanta robes_, and _winged bonnets_, for the equipment of female adventurers in the lists of gymnastic glory; while _flying trowsers_, _elastic jackets_, and _feathered buskins_, fit for Mercury himself, will contribute at once to the adornment, the swiftness, and the reputation, of our noble and ignoble racers.
