I proceeded ftill farther in the examination of this larger vefTel, 

 and I found it to be compofed of, at leaft, five fmaller ones, which 

 were placed in regular order, befide each other, and each feverally 

 formed in the fpiral manner I have mentioned. All thefe are fhewii 

 in /ig. 6, O P, and in the fame figure, at P Q, is to be feen the part 

 which I before mentioned liaving feen, as defcribed in^^. 5, at N. 



This circuitous figure of tlie veffels, may be exactly compared to a 

 brafs wire, twilled round a fmall rod, and the fame kind of formation 

 I have frequently, as I have before mentioned, feen in other woods. 

 And even in a ftraw I once obferved, by the microfcope, one of its 

 larger veffels to be formed, much in the fame manner as this I have 

 defcribed at O P. And, when we confider the fubje6l, we cannot, in 

 my humble opinion, conceive any form fo fuitable for thofe veflels to 

 raife the juices upwards. 



The fame gentleman from whom I received the lafl: mentioned 

 piece of Cocoa wood, fent me alfo two Cocoa nuts, inclofed in their 

 feveral fliells or coverings. From one of thefe I cut fo much of the 

 outer covering, as to exhibit the inner Ihell to view ; and I caufed a 

 drawing to be made of both, on a contracSled fcale, which is to be 

 feen a.tjig. 7, A B C D. The diameter of this external cafe or cover- 

 ing was nearly five inches and three quarters, meafured by the fcale 

 B D, which is five inches Ions. 



This external hufk or Ihell fo firmly adhered to the inner one, 

 being conne6ted to it by multitudes of veffels, that I found it a 

 work of confiderable labour, to tear it off. The inner fhell was 

 four inches in diameter, and, having cleared it from all the vefiels ad- 

 hering to it, I replaced it in the half of the cafe or hulk, as is to be 

 feen in the drawinsT. 



I have often been told, that the filaments of which this external 

 hufk or bark confifts, are of fuch a length that they are twilled into 

 cables, and alfo wove into fail-cloth. 1 proceeded, therefore, to exa-
