    ; 6] I am juftified very much by the ana-- logy of other Barks, and by the influ- ence of foil and expofure, in changing the appearances, and even of affecting the virtues of the fame fpecies of ve-. getables, to conclude, that the diverfity both in fize and colour of the Red Bark from the common Peruvian Bark, may depend either on the largenefs of the branches, or on other circumftances not neceflarily implying a fpecific difference in the tree.—On comparing the larger Bark of the Oak with its twig Bark even collected from the fame tree, I find the former of a reddifh colour, while the lat- ter is much paler, the roughnefs of the coat of the larger Oak Bark and its general ap- pearance may be compared to that of the Quill {mall curled Bark fo much efteemed in England, is the Bark of younger trees, which frequently recover the Barking, while the older trees never do. ‘This affords a ftrong proof, that the early Bark introduced into Europe was of the larger kind, and from the older » trees, while the difficulty of procuring it, has been the means of introducing a {mall and younger Bark, Mr, ARkoT, and all other Travellers agree in Pee | the Ked Bark to any other.
