"Portions of the rotting pulp were placed on a microscopic slide, divided into hundredths and thousandths of an inch. Fig. 21, A B, represents such a scale, the larger division, A B, representing the one-hundredth of an inch, and the smaller subdivision the one-thousandth of an inch; 7, 8, 9, 10, 11, 12, represent the cells of which the apples are mostly composed. The granular dottings represent apple starch. The branching cellular structure represents the mycelium of a fungus penetrating the cells. At 9, three small starch granuals are represented in a line, and are confined within the division of the one-thousandth of an inch." -Watts, 1874
