Note A — TWO NEW INSTITUTIONS OF SCIENCE;

In the letter alluded to, on examination, we discover another passage bearing on the point, which, owing to the Professor's modesty we suspect, he did not read. Prof. Mather adds. "You, so far as I know, first suggested the matter of such an Association. I laid the matter before the Board of Geologists of New-York, specifying some of the advantages that might be expected to result; and Prof. Vanuxem probably made the motion before the Board in regard to it."
