          gelatinous? Does not the mixture soon
become putrid and offensive? I have
used for botanical purposes a common
paste made of wheat flour to which is added
a little corrosive sublimate [mercuric chloride], a few grains
of which will effectically arrest fermentation
or mould, so that it may be kept for months,
even in hot weather, ready for use at any
moment. I have fear’d however, that the
paste of flour would invite the depredation
of insects, and that the small portion of the 
mineral poison would not prevent these
depredations.

I am looking very anxiously for the
parcel of Wright’s plants which Dr. Gray put 
in the hands of Little & Brown for me. They 
were requested to forward it by express a month
ago, but as yet it has not come to hand.

Very truly, my dear Sir,
I am with great esteem,
yours
