“ flowers of our female were never impregnated by 
“ the farina of the male. There is a male plant of 
“ this kind in a garden at Leiplic, twenty Go man 
iC miles from Berlin. We procured from thence in 
“ April 1749 a branch of male flowers, and fuf- 
“ pended it over our female ones ; and our experi- 
“ ment fucceeded fo well, that our palm-tree pro* 
(c duced more than an hundred perfectly ripe fruit ; 
“ from which we have already eleven young palm- 
a trees. This experiment was repeated lafb year, 
“ and our palm-tree bore above two thoufand ripe 
u fruit. As I do not remember a like experiment, 
“ I thought convenient to mention it to you j and, 
“ if you think proper, be pleafed to communicate 
“ it to the Royal Society.” 
In purfuance of my correfpondent's defire, I take 
the liberty of laying this account before you, which 
I think very curious ; not on account of its novelty, 
or of its confirming the fex of plants, which is now 
fufficiently eftablifhed; but on account of the male 
and female palm-tree’s flourishing fo completely, even 
under all pofiible advantages, in fuch high latitudes as 
thofe of Leipfic and Berlin. 
The impregnation of the female palm-tree by the 
male has been known in the moil antient times.
