present time, and introduce many more figures
& a number more, all which I think may be
done without increasing the price much if any. Would
Messrs. Wily & Putnam be likely to think favorably of
the proposition if it were made to them? Any suggestion
on the subject, at your convenience, would be
most gratefully received.

I shall ever remember my late visit to your
city, hasty as it was, with great pleasure and satisfaction.

Dr. B. is not, as I can learn, doing any thing
in particular just at the present time!

Please present my sincere regard to your
excellent lady and daughters, and also to Dr. Gray.
and believe me

As ever yours etc. John Johnston

Dr. J. Torrey

P.S. I left a small box in your laboratory
containing a small quantity of a powder that was
collected by Dr. Jackson in his survey of Maine at
Bluehill, and was labeled when it came into
my hands "Hydrate of silica." Does it contain infusia
in a fossile state?
