This fraction chart can be used for students to find A, B, and C in percentage. It can also be used to answer these questions (if it is 2.5 by 2 inches): "How many square inches in the entire figure? How many square inches in C? What part of a square inch is B? How large is A when compared to C? How large is B when compared to A? Into how many quarter-inch squares could you divide the whole figure?" -Foster, 1921

The illustration exhibits the typical characters of the red blood cells in the main divisions of Vertbrata. The fractions are those of an inch, and represent the average diameter. In the case of the oval cells, only the long diameter is here given. It is remarkable, that although the size of the red blood cells varies so much in the different classes of the vertebrate kingdom, that of the white corpuscles remains comparatively uniform, and thus are, in some animals, much greater, in others much less than the red corpuscles existing side by side with them.
