My dear Dr. Pammel:
I beg to acknowledge the receipt of your favor and also of the enclosures under separate cover which I consider very valuable contributions. I am still analyzing water and finding it very interesting. I shall await Prof. Buchanans answer with interest.
Again, thanking you for your kindness and with best wishes to all, I am,
Yours very truly,
