DR. MARTIN BARRY ON FIBRE. 
Fig. 144. Frog. Sketch of a large muscular fibril from the heart; a, on its 
edge (interspaces oblique) ; (3, on its flat surface (par. 92). 
Figs. 145, 146. Newt ( Triton cristatus , Linn.). Sketch of red blood-discs con- 
taining filaments ; a, on the edge (interspaces oblique) ; (3, on the 
flat surface (par. 92). 
Fig. 147- “Transverse section of the tooth of the Ornithorhynchus near the 
apex, where the tubes have become closer” (par. 99). 
Fig. 14 7|. From IIenle. (Allgemeine Anatomie. Lehre von den Mischungs- 
und-Formbestandtheilen des menschlichen Korpers, 1841. Taf. IV. 
fig. 5. 1.). From the nervus ischiadicus of the Frog ; “ a ausgetretenes 
Mark, (3 zusammengefallene Scheide.” 
Fig. 148. Man. Sketch of objects from the blood-clot. a. Parent cell ; filled with 
blood-corpuscles having the form of Ammonites. (3. More advanced states 
of such blood- corpuscles, discharged from a parent cell, and seen with 
others lying in a group. They have the spiral form. 7 . Similar blood- 
corpuscles of a larger size, i. e. in a state more advanced : the upper 
one beginning to undergo division. S. Spiral fasciculus of filaments 
(par. 97). 
Fig. 149. Newt ( Triton cristatus, Linn.). Sketch of blood-corpuscles from the form- 
ing clot. No addition had been made (par. 96). All are flask-like 
vesicles (par. 96). a. The membrane without folds. (3. Folds are seen. 
7 . The filament protruding. ($. Two filaments visible in the interior : 
the nucleus apparently giving them off. 
Figs. 150 to 152. Sketches of blood-corpuscles, and of filaments derived from them : 
as seen in the clot of the Frog and Newt. 
Fig. 150. Parent corpuscle, or cell, containing a coiled filament (a), which sur- 
rounds two young coiled filaments (J3, (3). A pellucid nucleus in 
each of the latter (par. 99). 
Fig. 151. Parent corpuscle, or cell, containing a coiled filament, which sur- 
rounds many young coiled filaments. 
Fig. 152. Coiled filaments, derived from blood-corpuscles: a, with a cavity in 
the centre ; (3, unwound. 
Fig. 153. Sheep. From the clot of blood: nine hours after the bleeding. Sketch 
of filaments, a. A spiral having been produced, it is elongating. (3. The 
elongation has proceeded farther ; and at 7 has produced the appearance 
of a merely twisted filament. Of these filaments, about half a dozen lay 
abreast, and some of them were united at their extremities. Structure 
of the filaments, s. Similarly twisted filaments. Spiral; apparently 
an altered red blood-disc. The whole blood-red. 
Fig. 154. Newt ( Lissotriton j)unctatus,T3v.Li). From the blood-clot. Sketch of an
