          Please let me know in answer what you want of these things & I will
make up a parcel & forward it to you through Dr. Gray. It is not my
habit to stipulate for any return in exchange not do I find such stipulations
of any use in practice as [?] have had 60 or 70 specimens
foreign minerals without the [added: unasked?] promised return. I am too happy to find
those interested in minerology with whom to divide my surplus specimens.
Nevertheless I should be happy to receive any New Jersey or other specimens 
of which you have plenty. Alger has recently returned from thence & as
I understand has obtained fine specimens green & blue spinelle of
crystallized dark blue sapphire & many others. I am in great hopes
that this branch of natural history is looking up here. Certainly
the students are rather on the increase. But the means of instruction
and the ability of procuring specimens are rather small. I have filled
my sheet but whether it is after all worth you reading I do not know. Please
accept the wish to make it interesting for the deed[?] truly yours
