The sailing clubs upon the Thames, comprise the Royal Sailing Society—the Royal Thames’ Yacht-club—the Clarence—British—Royal Yacht, and several minor associations. Throughout the season several cups and prizes are annually given; and the severe and spirited contests between the beautiful small craft which form these fancy fleets, are highly interesting.

The sailing matches on the river are divided into two classes—one above, and the other below the bridges. The smaller yachts, ranging from six to twenty-six tons, are commonly entered for the former, while a larger class contend for prizes sailed for between Greenwich and Gravesend.

These elegant and truly national amusements, appear to be rapidly gaining a prominent place in the list of fashionable recreations; and aquatic sports now occupy that dull and sombre season, from the period hunting ends, till russet autumn summons the sportsman to the field.

There are placed in the neighbourhood of joints certain bags, containing a mucous fluid for the purpose of lubricating the parts, and these sometimes become inflamed and enlarge. A similar enlargement is found above the hock, between the tendons of the flexor of the foot, and the extensor of the hock. As from its situation it must necessarily project on both sides of the hock, in the form of a round swelling, it is called a thorough-pin. It is an indication of considerable work, but, except it be of very great size, it is rarely attended by lameness. The mode of treatment must resemble that recommended for wind-galls. Although thorough-pin cannot be pronounced to be unsoundness, yet it behoves the buyer to examine well a horse with thoroughpin, and to ascertain whether undue work may not have injured him in other respects.—The Horse.
