As the parent cell is forming, the new discs within it gradu- 
ally become red, and are at length liberated to give origin in 
like manner to new discs, or to be appropriated in some other 
way. 
3. From § 4 it will be seen that the disc, or so-called ‘ cy- 
toblast,” is originally a pellucid globule; which globule there- 
fore is the true cell-germ. 
7. Sometimes the quantity of the pellucid substance in the 
blood-cell is very much increased. ‘This takes place at the 
expense of the red colouring matter which surrounds it. ‘The 
blood-corpuscles, now cells, I have seen in various parts col- 
lected until the capillaries were completely jil/ed with them, 
and until they had become pressed together into many-sided 
objects. I have met with vessels at the edge of the crystalline 
lens, some parts of which presented no other than the pellucid 
semifluid substance, arisen in the manner now described, and 
no longer contained within the cells. 
8. This originally colourless substance, derived from the 
nuclei of blood-cells, and nearly filling the capillaries as I 
have found it, appears to constitute the essential part of coa- 
culable lymph, to organize the same, and to give origin to the 
tissues, &c. in the manner I have elsewhere described. It 
seems to be this same originally colourless substance, derived 
from the nuclei of blood-cells, that forms the exudation-cor- 
puscles of authors, the fibres of false membrane, and the fila- 
ments in coagulating blood — filaments which, as I have 
shown, here and there arise while this substance is still within 
the cells.
