But, as thefe fmallcr vefTels, which are plainly to be fcen by the 

 microlcope, cannot, by reafon of their minutenefs be well expredbd 

 in a drawing, unlefs ftill more enlarged, I ufed a niicrofcope of greater 

 inagnifying power, and cauied a fmall portion of the wood which 

 in Jig. 6, is iituated between the two larger veflels, K and L, to be 

 drawn fomewhat larger than it appeared through the inici'ofcope be- 

 fore w'hich it was placed, and this is fliewn mjig. 7. ABCD. 



This piece of wood was fo cut, that all the horizontal veflels were 

 exactly divided, and I could plainly perceive them, whether I 

 viewed tlie obje<5l up\^•ards or downwards ; and I further faw% that 

 where the horizontal veflels lay, there the larger tubes of the wood 

 were fituated, as appears in this figure at AB, and DC, which is 

 where the horizontal velfels were fituated. 



h^Jig. 6, are alio fliewn, the horizontal veflels which take their 

 courfe among the perpendicular veflels or tubes of the wood, but, as 

 all the afcending veflels or tubes are cut tranfverfely, fo that their 

 cavities become confpicuous, on the contrary, the horizontal 

 v-eflels, by this manner of cutting, preferve their fliape as near as 

 may be. Jn this figure there appear more of thefe lafl veflels about 

 the parts marked A and B, than about G, or between G and F ; the 

 rc'afon of wliich is, that in fplitting the wood, the knife did not pafs 

 in lb firaight a direction along thole veflels as I wiflied : for the 

 fame reafon thefe horizontal veflels appear in greater numbers at E, 

 or between E and F, tlian about C. 



hi thefe horizontal veflels may Ijc feen a red and yellowifli fub- 

 (lance, fmiilar to the oily matter in tlie Nutmeg, and the young 

 plant it contains, fo that the horizontal veflels arc of a reddifh colour. 

 Fartlier, I determined to cut thefe horizontal veflels, each of which 

 can be diftinctly feen, and which generally lie three, or at the moft, 

 four together in rows, in an oblique manner, fo as to exhibit their 

 cavities to view. A fmall particle of tlie wood reprefented &tfig. 4,
