Thayer's Note:

a For an indication of the type of work involved, see the interesting article by Florian Cajori, Isis, Vol. 12 No. 3 (Dec. 1929), "History of determinations of the heights of mountains", p514, in which he is mentioned.

I was tipped off to this article by Prof. Rickey's page, that gathers biographical and bibliographical information on Gen. Cram.
