vifes, that feeds fhould be fent in tight cafks, and 
placed on or near the deck, fo as to have the benefit 
of the frefh circulating air, at the lame time the 
tightnels of the cafk would fecure them from the

In order to fend the governor a frefh fupply of 
cork acorns, in a growing (late, I tried the following 
experiments on them to preferve them found; the 
effedt of which I expedt to have the honour to lay 
before this Society next fummer : but as I tried the 
very fame experiments, at the very fame time, on a 
parcel of frefh oak acorns, which I collected myfelf 
at Sydenham in Kent, the latter end of laffc Odtober, 
and have fince kept them by me in a box in a warm 
room, it may give us fome infight into what may be 
the fate of thofe that are fent abroad.

and 30th of Odtober 1758 ; and the acorns cut open 
to fee the effedts, Jan. 17, 1759. 
Experiment 1 . Acorns of the Englifh oak fmeared

folded in a piece of paper, and put into a deal box. 
When thefe were cut open, they appeared hard, 
dry, and inclining to black, being quite perifhed. 
When I firft thought of making this experiment, 
I imagined, that the perfpirable matter of the kernel 
of the acorns could not pafs through the glafly, clofe 
fubflance of the gum arabic ; but experience has con- 
vinced me of the contrary. 
Exp. 2 . Some acorns, treated as in the firft expe- 
riment, were wrapped up in papers, foaked in a ftrong 
folution of gum arabic, each in a feparate paper:
