86 MR. T. WHARTON JONES ON THE BLOOD-CORPUSCLE CONSIDERED IN 
Second Pha.se. — Nucleated Cell. 
Fig. 4. Nucleated cell, uncoloured stage. The cell- wall, which is very pale, is seen 
all round the very distinct cellseform nucleus. 
Fig. 5. Nucleated cell, uncoloured stage. The cell-wall, which has just been brought 
out by distention with water, is extremely pale, and is seen only on one 
side of the very distinct cellseform nucleus. 
Fig. 6. A nucleated cell in transition to the coloured stage. 
Fig. 7 a - Nucleated cell, coloured stage, circular. 
Fig. 7 b. The same, after the action of acetic acid. 
Fig. 8. Nucleated cell, coloured stage, oval. 
Third Phase. — Free Cellaform Nucleus. 
Fig. 9. Free cellseform nuclei, coloured stage, or “ red corpuscles,” similar to those 
of the fully-formed blood of the animal. 
Man and the Mammifera. 
First Phase . — Granule-cell. 
Fig. 1 a. The granule-cell of human blood in its coarsely granular stage distended 
by water. 
Fig. 1 b. The same, after being acted on by acetic acid. The granules have been dis- 
solved and a single cellseform nucleus disclosed. 
Fig. 2 a. The granule-cell of human blood in its finely granular stage in a state of 
collapse. 
Fig. 2 h. The same, distended by water. 
Fig. 3 a. The granule-cell, coarsely granular stage, of the blood of the Horse. 
Fig. 3 h. The same, after being acted on by acetic acid. 
Fig. 4. The granule-cell, finely granular stage, of the blood of the Horse. 
Fig. 5 a. The granule-cell, coarsely granular stage, of the blood of the Elephant. 
Fig. 5 h. The same, in process of being acted on by acetic acid. 
Fig. 6. The granule-cell, finely granular stage, of the blood of the Elephant. 
Second Phase. — Nucleated Cell. 
Fig. 7- Nucleated cell of human blood, uncoloured stage, distended by water. 
Fig. 8. The same, in a state of collapse. 
Fig. 9. Nucleated cell of the blood of the Elephant in its uncoloured stage. 
Fig. 10. The same, in a state of transition from the granule-cell. 
Fig. 11. Nucleated cell, uncoloured stage, of the blood of the Goat. 
Fig. 12. Nucleated cell, uncoloured stage, of the blood of the Paco. 
Fig. 13. Nucleated cell, coloured stage, from the blood of the Horse. 
Fig. 14. Nucleated cell, coloured stage, from the blood of the Elephant.
