APPENDIX. 
I shall carry them forward to Sydney, accord- 
ing to your instructions, and have no doubt of 
delivering them into the hands of Mr. Cunning- 
ham in the same flourishing state in which they 
are at present. 
Allow me, in conclusion, 'to offer to you my 
warm congratulations upon the success of this 
simple but beautiful discovery for the preserva- 
tion of plants in the living state upon the longest 
voyages ; and I feel not a little pride in having 
been the instrument by which the truth of your 
new principle has been fully proved by experi- 
ment. I am, Sir, &c., 
Charles Mallard. 
To N. B. Ward, Esq.

Copy of a Letter from Mr. Traill to the Author. 
Cairo, April 30 ill, 1835. 
Sir, 
I beg to acknowledge the receipt of your 
letter of the 2nd ult., wherein you request in- 
formation as to the state of the plants sent by 
you in the Nile steamer.* The collection con- 
sisted, I believe, of one hundred and seventy- 
three species, contained in six glazed cases, two 
of which only were forwarded to me from Alex- 
* In August 1834.
