THE CELL DOCTRINE. 107 



are, however, a few points of difference; some, per- 

 haps, purely in mode of expression, but others as to 

 matter of fact, which would seem to be appropriately 

 here recorded. And, in order to give completeness 

 to any expression of such views, he has thought best 

 to state them connectedly, though briefly. 



The author believes the ultimate physical element 

 of organization, to be what is commonly called the 

 " cell," or " elementary part," and that it is com- 

 posed of matter in two states. The one, central in 

 its situation, to which Dr. Beale has most appropri- 

 ately given the name "germinal matter;" the other, 

 for the most part peripheral in its situation, which 

 the same observer has called " formed matter." The 

 former, which is the " sarcode " of Dujardin, the 

 "protoplasm" of Max Schultze, is that upon which 

 the origin and existence of the cell depends. It is de- 

 rived by division, budding or proliferation from pre- 

 viously existing matter of the same kind, and it alone 

 has the power of growing by converting nutritious 

 matter or " pabulum," derived from the blood or 

 other sources, into material like itself. Without 

 germinal matter textures cannot be reproduced or 

 continued. 



In appearance, germinal matter is often structure- 

 less, especially as constituting the living moving 

 matter of the protozoa or lowest animals of the 

 rhizopod type, as the amreba. Yet it is not always 

 structureless, but often granular in its appearance, 

 and as constituting the mass of rapidly growing 

 cells in health and disease, in the higher animals, 

 is indeed usually granular, as is evident from the
