as visitors to view with him the state of the land previous to the experiment, inspect its progress, and report the result.

The President for the year 1803 is Sir Henry Vane Tempest, Bart.; and two meetings of the society have already been held, on 1st of April and 1st of June.

Spanish Wool.

It has been proved, by his Majesty's Spanish flock, in ten years experience, that the wool of that breed does not degenerate in this country. It is ascertained that the first cross of a new breed gives the lamb half of the ram's blood; that the second gives 75 per 100; the third 87; and the fourth 93, The difference between the fleece of the original stock and the wool of the mixed breed is then scarcely perceptible, particularly if attention has been bestowed on the selection of the ewes.

Substitute for Soap.

In the eleventh number of the Repertory of Arts, &c. we published Mr. Vancouver's specification of his patent for a method of preparing an earth, found on Lord Warwick's estate, to be used as a substitute for soap, and particularly for cleansing wool. A similar kind of earth, and possessing the same detergent properties, is found in many parts of the Yorkshire Wolds; it is composed of clay, sand, and the oxyd of iron, and it is used for washballs. The only difference between them appears to be, that in Warwickshire the earth is of a green, grey, lilac, or white colour, whilst that of Yorkshire is generally of a yellowish- white. The former is held together by a strong size; the latter has hitherto been seldom used in washing linen, as it rapidly dissolves in water, but that defect has been corrected by the mixture of glue.
