that wood. In the same figure, as mqvt shows one of those horizontal vessels, 

 continued from the wood, and carried on into part of the bark, which is repre- 

 sented by aTT, so between a and v are shown a few of those vessels which 

 sprout out of the said horizontal ones, and run circularly about the bark ; and 

 how carefully soever I observed them, I could not discover one ascending canal ; 

 which must needs run lengthwise up the bark, in case the bark had its rise from 

 the root of the tree. Fig. 6 shows also a thin scaly particle of the bark of the 

 said wood before a microscope; the vessels or canals of which run also horizon* 

 tally from a to b, or from c to b. Fig. 7 shows also a small scale of the bark 

 tf the twig of a tree, in which the vessels represented by wx or zy run cir-t 

 cularly ^bout the wood; but I have forgotten to what tree it belonged. 



In another piece of cinnamon wood, says Mr. L. I have inquired into that 

 part of the bark that lies next, and is as it were joined to the wood, and in 

 cutting it to pieces have satisfied myself more than ever, that the cinnamon^ 

 Otherwise called the bark, receives both its nourishment and increase from the 

 wood alone, and not from the root; for when I divided this bark into small 

 parts, I could discover no ascending vessels in it ; but on the contrary, so many 

 horizontal vessels coming out of the wood, and those too so large, that I do 

 not know that ever I have discovered so many vessels in the barks of any other 

 trees. Fig. 8 shows a very small particle of the bark of a cinnamon tree, in 

 which the horizontal vessels lie by each other in such order, as is here repre- 

 sented between lmnrs, or between noqr, in which they are all cut across. 

 We also see that about the horizontal vessels there lie oblong parts, that run 

 into a point at both ends, which parts, represented by lmn, lie together ; we 

 may observe also how the said parts surround the horizontal vessels. 



All the said long particles, which in a great measure compose the cinnamon 

 bark, are not incurvated, as in fig. 8 ; but many of them are extended in right 

 lines, as in fig. Q, which represents a very small particle of the abovementioned 

 long parts, which likewise incloses some horizontal vessels; and wherein may 

 be seen at a how regularly the sharp points are ranged by each other, as also 

 between bp and ce, between which the horizontal vessels are to be seen in that 

 order in which they always lie. That sharp and pointed particle represented by 

 PH, seems to be out of its place ; and I fancied that in dividing it from the 

 other parts, I might have broke it off at p. 



I also placed 3 other long sharp pointed particles before a microscope, as in 

 fig. 10; where we also see in how regular an order the pointed parts appear, as 

 in KM for instance; from whence we may conclude, that all the other parts of 

 the like nature are disposed in the same manner. Fig. 1 1 shows another pointed 

 particle, that was exceedingly incurvated, which I suppose might be occasioned
