B Dn. SwanTZz Botanical Hifiory 
Sir Hans SLOANE, we find, was convinced of the difference -be- 
tween them, as he gave feparate defcriptions of each, in the Tranf- 
actions of the Royal Society. Notwithftanding this, he feems to be 
in fome doubt (probably through want of fyftematic knowledge) 
if the difference might not depend upon the place of growth: at 
leaft, he fays, the one may ferve as a good fuccedaneum for the 
other; though he confeffles that the true Winter’s Bark is much 
the more aromatic of the two. 
The Canella alba is to be found as well in the TS No. 192, 
p- 462, as in the Hiffory of Jamaica, vol. ii. p. 87 ; where the author 
calls it 
Arbor baccifera laurifolia aromatica, fruétu viridi calyculato. 
The botanical diftinétion was afterwards paid very little attention 
to by feveral writers on the Materia Medica; as Lemery, Pomet*, &c. 
And it is to be fuppofed that they have led Linnzus (not attending 
to the evidence of the old botanifts) into this error of combining 
two different genera under the name of Laurus Winteranat: but 
he feparated this fpecies from Laurus, in the enfuing editions, as a 
diftinét genus, and called it Winterania; under which name it has 
been univerfally but improperly known. : 
This miftake has however been fully developed by the late difco- 
very of the Cortex Winteranus of Clufius and Sloane, a production 
of Wintera aromatica (from the neighbourhood of the antarétic 
regions), whofe exiftence has remained in oblivion nearly a century, 
fince it made its firft appearance in the Tranfaétions of the Royal 
Society, in the year 1692. 
It is the late Dr. Fothergill who has, with the affiftance of Dr.
