DESCRIPTION OF PLATE IX., 



Illustrating Dr. Thudichum's paper on Green Pigment 

 Degeneration of Muscle. 



Fig. 

 1. — Piece of degenerated muscular tibre from wall of left ventricle. 

 Transverse striae interrupted by longitudinal lines. Granular 

 green pigment scattered along the axis of the fibre. 



2. — Pieces of fibre with longitudinal lines (the strias have disappeared) ; 

 a, nucleus, and pigment deposits at both ends of the nucleus; 

 h, patch of pigment corpuscles, found at equal distances along 

 a fibre. 



3. — Pieces of fibre, much macerated, from the right ventricle. Transverse 

 strife little indurated. Exhibits the striking difference of true 

 fat (h) from pigment (a). 



4. — Nerve fibril from right septum. 



5. — The same after boiling with ether and cooling. The cylinder axis 

 (serrated) has disappeared, and fat globules are deposited against 

 the outer membrane of the fibril. 



Illustrating Mr. Weston's paper on Actinophrys Sol. 



Fig. 



3. — Actinophrys Sol drawn by Camera lucida ; a a, two Vorticell;© en- 

 closed in a vesicle ; h, vesicle. 



4. — A. Sol in the act of self-division. 



5. — A. Sol ; a, an animalcule ; h b, two expanded cells. 



6. — Actinophrys ; a, Chaitonotus larus engulphed ; h h b, three Rotifers 

 caught ; c, the valve. 



7. — A, Sol seizing a Vorticella ; a, Vorticella.
