    Fig. 4. Transverse section of a portion of the wall of a large gland-vesicle from the thyroid gland of a Conger Eel, hardened in alcohol and stained with hsema- toxylin. (Obj. 6, oc. I., tube half drawn out.) 1, Cavity of the large vesicle. 2, 2. Its epithelial wall, of which the cells are represented semi-diagramatically. 3, 3. Small vesicles, which are situate in the epithelial wall of the large vesicle and are separated by much flattened epithelial cells from the cavity of the latter. 4, Another vesicle, separated by cells less flattened from the cavity of the large vesicle. 5, 5. Vesicles distinctly outside the wall of the large vesicle, which appear to be growing outwards. The homogeneous contents of the small vesicles are seen with their jagged outlines. The vesicles represented in this drawing are not all quite on the same level. Fig. 5. From a section of the thyroid gland of the Tortoise, hardened in a 1 per cent, solution of chromic acid (17 hours) and subsequently in diluted and in strong alcohol, and stained with hsematoxylin. The intercellular reticulum is seen from the surface, but the intervening epithelial cells are not repre- sented. (Obj. F, oc. I.) Fig. 6. From a section of the thyroid gland of the Conger Eel, hardened in alcohol and stained with hsematoxylin, giving a surface view of the epithelial cells amongst which are seen the branched nuclei of the club-shaped cells. They are probably connected with the intercellular reticulum. (Obj. 6, oc. I., tube half drawn out.) Fig. 7. From a section of the thyroid gland of the Tortoise prepared as follows : injected by the method of puncture with ^th per cent, solution of osmic acid, hardened in a 1 per cent, solution of the same acid for five hours, and sub- sequently in alcohol, mounted in glycerine. It shows (at i) the epithelial wall of a vesicle cut obliquely, beyond which there projects (at 2) a membrane having delicate wavy strise on it. (Obj. F, oc. I.) Fig. 8. From a longitudinal section of the thyroid gland of a Kitten injected with nitrate of silver by the method of puncture, hardened in alcohol and stained with hsematoxylin. The drawing represents a portion of the wall of a vesicle seen from the surface. By focussing from the interior of the vesicle, three layers can be distinguished. First, the oval-shaped nuclei, at regular intervals, stained with hsematoxylin ; secondly, a layer of dots and short strise, stained with nitrate of silver, only represented in the centre of the drawing ; and thirdly, the outlines of the endothelial cells of a lymphatic, also stained with silver (1, 1).
