Fig. 6. Sparrow. From the coagulum of blood, a, (3. Blood-corpuscles (coils) un- 
winding themselves into the straight and parallel filaments of the coa- 
gulum (par. 8). The filament (3 is on its edge (par. 6). 
Fig. 7- Chick ( Phasianus Gallus, Linn.) in ovo, incubated twelve days. Sketch of 
blood-corpuscles (coils), which are unwinding themselves as filaments, 
a. Parallel filaments, in the same field of view. Blood-red. From the 
wing. Similar objects seen in the leg (par. 8). 
Fig. 8. Turtle. Sketch of blood-corpuscles containing filaments. In all of these 
corpuscles, the filament is formed at the outer part. Between this outer 
part and the centre, the corpuscles a , (3 present discs arranged in lines 
for the formation of a further portion of the filament (par. 25). In 
the coagulum of blood of the Turtle, the same unwinding of corpuscles 
into filaments was seen, as is described in the explanation of fig. 10. from 
the Newt, and in other figures. 
Fig. 9. Frog ( Rana temporaria, Linn.). Sketch of blood-corpuscles containing fila- 
ments. «. Even the central part is unwinding itself into a filament. 
(3. Exhibits a spiral arrangement of the filament, y. Filament on its edge 
at one part : indistinct at other parts in this corpuscle. &. Discs, also, seen 
in this corpuscle : their outer part having very much the appearance of a 
filament. 
Fig. 10. Newt (Lissotriton punctatus, Bell.). Sketch of blood-corpuscles containing 
filaments, which are represented only in certain parts, a. The nucleus is 
double (pars. 98^, 99). (3. The outer part of the nucleus resembles that 
of a ball of twine, from its consisting of a filament, y. The nucleus un- 
winding itself into a filament. c$. The filament on its edge (par. 6). 
s. Nucleus removed from its corpuscle. It is unwinding itself into a fila- 
ment. Corpuscle giving off a filament from its outer part. q. Filaments, 
some of them parallel, into which some of the corpuscles have passed. 
This blood had stood for a while in the microscope (par. 8). 
Fig. 11. Toad (Rana Bufo, Linn.). Sketch of blood-corpuscles containing filaments. 
a. The coil-like form of the filament is seen. (3. Represents the outer por- 
tion of the filament lying on its edge ; and rendering this part of the cor- 
puscle thicker than that immediately internal to it ; as well as giving to 
the corpuscle the appearance of being abruptly cut off (par. 2). y. In a 
condition less advanced than a : there being in y more of the central part 
still in the state of discs (par. 2). 
Fig. 12. Skate (. Raia batis, Linn.). Sketch of blood-corpuscles, each containing a 
coiled filament. This filament on its edge at the circumference (see the 
explanation of y, fig. 11 and par. 2). 
Fig. 13. Cod ( Gadus Morrhua, Linn.). Sketch of blood-corpuscles more or less ad- 
vanced in giving origin to filaments, a. The formation of the filament is
