Description of Plate. 
Fig. 1. Action of prussic acid on blood— (a.) Two red cor¬ 
puscles, one empty and tlie other full. (b.) White corpuscles, 
right fig. exhibiting a macula or spot on its wall, (c.) White 
corpuscles with nuclei in different forms, (d.) Left fig. exhibiting 
a double envelope. ( e.) Starch bodies. (/.) A mass of blood 
corpuscles after the full action of prussic acid ; the red have parted 
with their molecular contents, and some blue particles are also 
seen ; all the nuclei exhibit a blue tint re-action. Par. 6, 12, 19. 
Fig . 2. Red corpuscles subjected to the combined action of 
prussic and nitric acids—the principal feature being the oval 
form assumed by the red ; the colourless spaces are empty portions 
in each corpuscle ; all exhibit a blue tint. 
Fig . 3. The action of tincture of liammamelis on the red 
corpuscles—some showing granular contents, others the same, 
crumpled up; one quito empty, with thickened walls; another 
with three nuclei, which exhibited motion for some time. Par. 19. 
Fig. 4. The action of nitric acid on red corpuscles—some are 
oval, and their contents variously corrugated ; these have been 
coloured by magenta; the next are extremely dilated and coloured 
also; the three remaining are softened, exhibiting nuclear forms. 
Par. 19. 
Fig. 5. Action of carbolic acid—the red corpuscles exhibit 
colourless spaces; the two right hand figures are the result of 
carbolic acid and glycerine ; one is nearly empty. Par. 14. 
Fig. 6. The action of cupreate of ammonia on the red corpuscles, 
coloured by magenta—one solid and spherical, the next flattened 
and empty in the centre; the next concavo-convex. The two 
figures below are starch bodies, measuring about to 
of an inch. These have been tinged by iodine. Par. 8, 19. 
Fig . 7. Blood after the action of prussic acid tinged with 
magenta—empty red corpuscles, with molecules coloured by the 
dye; white corpuscles, with tinted nuclei and starch body. 
Par. 6, 12.
