ree Poe CE. xiil 
This Letter, which was read to the Society 
the 2d of May, 1751, with fome ingenious Ob- 
fervations on the fame Subject, by Dr. War/on, 
F. R. S. to whom it was addreffed *, has efta- 
blifhed the Fact, attefted by the Ancients, con- 
cerning the Palm-Tree, which fome may per- 
haps have looked upon as fabulous; and, as the 
Fruétification in other Vegetables, though it may 
differ in particular Circumftances, has yet in 
general a manifeft Conformity with that of the 
Palm-Tree, in refpect to the Parts fuppofed to 
be the Organs of Generation, which are difcover- 
able either on the fame, or on a feparate Flower, 
in all but the Clafs Cryptogamia, where they are 
too minute for Obfervation ; fo from this fingle 
Experiment we may fairly draw an Argument 
by Analogy, for the Confirmation of the whole 
fexual Hypothefis: But there are, as has been 
faid, other, and better Proofs. We have already 
directed the Reader to thofe ftated by Linnaeus ; 
whoever defires farther Satisfaction concerning 
this Point, may fee the feveral Demontftrations 
collected, and methodically conne¢ted in the 
Sponfalia Plantarum of F. Gufavus Walkbloom, 
* Printed alfo in the Philofophical Tranfactions with 
the Letter.
