    EXPLANATION OF THE PLATE. [All the objects in this Plate, with the exception of Figs. 9, 12, 13, and 14, are magnified 400 diameters.] 1. Red corpuscles of the blood, seen on the flat surface, laterally and in rolls. Diameter = 3JL_th to gj^th inch. 2. White or colourless corpuscles of the blood.—a. in the natural state, diameter = t0 asroth >ncl> !—b. a single corpuscle treated with dilute acetic acid (about 1 part of acid to 5 of water), showing the tripartite nucleus. 3. Pus corpuscles.—a. three in the natural state, diameter = ^th to ^th inch ; —b. two corpuscles treated with dilute acetic acid, one showing a tripartite, and the other a quadripartite nucleus ; under the action of the acid, the diameter is slightly diminished. 4. Compound granule corpuscles.—a. in the natural state, diameter = j^th to •jgLjth inch;—b. corpuscle about to undergo rupture; the involucrum becoming more transparent; and the granules larger, darker, and more prominent;— c. a corpuscle treated with dilute acetic acid ; the involucrum being rendered transparent, the granules more evident, and several nuclei appearing in its interior. 5. Epithelium scales from the Mouth (of medium size).—Diameter = j]gth to ^th inch. Diameter of nucleus = j^gth to^th inch. Ga. Enccphaloid (fresh) from the Stomach.—Spherical nucleated cells in different stages of development. Some of the cells young, with the nucleus single and large in proportion to the size of the entire cell. In others the nucleus has divided, and the cell is of larger relative size. Diameter = j^th to -^th inch. Diameter of nuclei = gjggth to —th inch 6b. From the same specimen as 6a.—Nucleated cells of irregular form, all more or less elongated, and beginning to branch out. Nucleus single or double. Dimensions : Length -j^gth to fgggth inch ; width g^gth to gg^th inch. 7. From the same specimen.—Caudate nucleated cells of various forms. Nuclei more or less compound. Dimensions : Length -j^th to Jjth inch ; width .2Jroth t0 5500th inch- 8. From the same specimen.—Broken granular matter; fibrils; and three globules of oil of different sizes. The granules vary in diameter from jJggth to Tggggth or tggggth of an inch. 9. Vertical section of carcinoma of the Breast; exhibiting enlargement of the lactiferous ducts, with thickening of their walls. Some of the ducts are cut across transversely, others longitudinally.
