My Lord, 
Read Dec. 20,^ N a letter , which I took the liberty to 
addrefs to your Lordfhip, dated Jan. 
18, 1759, relating to fome experiments, which I 
had made to preferve the acorns of 'Engli/h oaks for a 
longer time than ufual, in a perfect date of vegeta- 
tion, I there took notice, that I had fent fome acorns 
of the cork oak to the governor of Georgia \ preferved 
in much the fame manner : but as the fubdances I 
made ufe of for this purpofc differed a little, I fhall 
defcribe thofe experiments here more particularly . 
On the 2.7th of Nov. 1758, I prepared [even par- 
cels of the acorns of the cork-bearing oak or ilex, in 
the following manner : 
N° 1. 15 acorns, each covered over iingly with a 
ftiff folution of gum arable , and afterwards 
rolled up in gum d paper. 
N° 2. 13 D°. each rolled up in a thin cover of com- 
mon yellow becs-wax, foftened before the 
lire, and rolled up afterwards, feparately, 
in white paper . 
N° 3.
