Copy of a Letter from Charles Mallard, Esq., 
R.N., to the Author. 
Hobart Town, November 23rd, 1833. 
Sir, 
You will, I am sure, be much pleased to 
hear that your experiment for the preservation 
of plants alive, without the necessity of water 
or open exposure to the air, has fully succeeded. 
The two boxes entrusted to my care, contain- 
ing ferns, mosses, grasses, &c., are now on the 
poop of the ship (where they have been all the 
voyage) ; and the plants (with the exception of 
two or three ferns which appear to have faded), 
are all alive and vigorous. 
During the very hot weather near the equator, 
I gave them once a light sprinkling of water, and 
that is all they have received during the passage. 
All the plants have grown a great- deal, par- 
ticularly the grasses, which have been attempting 
to push the top of the box off.
