100 MR. T. WHARTON JONES ON THE BLOOD-CORPUSCLE CONSIDERED IN 
Insecta. — Beetle. 
First Phase. 
Granule-cell as it appeared when the blood was examined as soon as possible 
after being - drawn. 
The same, changed in shape — the cell-wall shot out into processes — as it ap- 
peared soon after the blood was drawn. 
The same, after the action of water. 
Second Phase. 
Nucleated cell, as it may sometimes be seen when the blood is examined 
immediately on being drawn. 
The same cell, changed in shape. The cell-wall extremely pale, shrivelled, and 
shot out here and there into processes. 
The same, distended by water. 
Insecta. — Chrysalis of Cabbage-butterfly. 
First Phase. 
and 8. Granule-cells in coarsely and finely granular stages. 
Granule-cell, with the cell-wall shot out into processes. 
Second Phase. 
Fig. 10. Nucleated cell of its original shape. 
Fig. 11. The same, with the cell-wall shrivelled and shot out into processes. 
Fig. 12. The same, distended by water. 
Annelida. — Earth-worm. 
First Phase. 
Fig. 1. Granule-cell, coarsely granular stage. The cell-wall shot out into a single 
bud-like process. 
Fig. 2. Granule-cell, finely granular stage. The cell-wall shot out into cilia-like 
processes. 
Figs. 3 and 4. The same cells distended by water. 
Second Phase. 
Fig. 5. Nucleated cell with its cell-wall shot out into processes. 
Fig. 6. The same, distended by water. 
Annelida. — Medicinal Leech.
