The complete circumference of each and every of these streaks was about the thickness of a hair of one’s head. . . all consisted of quite small green globules joined together: and there had been quite several tiny green globules as properly.”. . . my perform, which I’ve done for a lengthy time, was not pursued in order to achieve the praise I now appreciate, but chiefly from a craving following knowledge, which I notice resides in me far more than in most other men. And therewithal, anytime I identified out anything outstanding, I have thought it my duty to place down my discovery on paper, so that all indigenous individuals may be informed thereof ( Waggoner).
