compaL^ed and conjoined together, that they feem to be one fingle 

 piece of wood ; as if we were to figure in imagination a number of 

 fmall holes, bored in the moll exadl order and proportion, in a piece 

 of the hardeft wood. 



Fig. 11, II, are the horizontal veflels cut tranfverfely : two 

 of thefe may be feen lengthwife, infg. lo, at the letters ABC and 

 H H. Fig. 11, LL, are the fmaller perpendicular veflels cut longi- 

 tudinall}^ 



Fig. 13, A BCD, is a very fmall piece of Box-wood, drawn from 

 the fame microfcope as the piece of Ebony before-defcribed ; and, 

 although I examined this wood veiy attentively, I could not perceive 

 in it any appearance of alteration in its texture, as refpedting or de- 

 noting the diiFerent feafons of the year in which it was produced ; 

 for which reafon I made a drawing of no more than one minute 

 particle, here reprefented. I found this wood to conllll: of two 

 forts of perpendicular or aflending 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 Jig. 14, where the 

 larger veflels are fliewn, cut longitudinally, as denoted by the 

 letters EEEE. 



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 Jig. 14, at FF. 



A B, or C D, are the horizontal vefl!els, as they appear viewed 

 lengthwife, and cut tranfverfely, they are fliewn in Jig. 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 fliew the 

 wonderful make of this wood, I have caufed a drawing to be made
