Fig. 11, II, are the horizontal veflels cut tranfverfely: two of thefe may be feen length wife, in fig. lo, at the letters ABC and H H. Fig. 11, LL, are the fmaller perpendicular yetfels cut longi- tudinally.

I found this wood to confifl of two forts of perpendicular or alfending veflels, namely, a larger fort and a fmaller, intermixed with the larger. The larger veflels are compofed of fine membranes, full of parti- cles wonderfully minute, which are reprefented in fig. 14, where the larger veflels are fliewn, cut longitudinally, as denoted by the letters EE EE. The cavities of the fmall veflels are very much like to thofe in the fmall veflels of the Ebony-wood, and thefe, when cut longitu- dinally, are fhewn in fig. 14, at FF. A B, or C D, are the horizontal veflels, as they appear viewed lengthwife, and cut tranfverfely, they are fhewn in fig. 14, at GG. I have often examined the Lime-tree, as well that which is brought to us from Norway to be ufed in carving wooden figures, as that which grows in this country; and, in order to fhew the wonderful make of this wood, I have caufed a drawing to be made
