These molecules, throughtheir own vital forces, collect themselves into groupsof nuclei, which (it is supposed) become convertedinto cells,* from which the future tissue is devel-oped.! The fibrine soon becomes permeated withblood-vessels, which convey the materials for the fu-ture nutrition and growth of the tissue into w^iichit is converted; and these are, most probably,formed as in the embryo, by the development of cellswhich open into each other in continuous lines. Thetime within which recently effused fibrine may ac-quire vascularity, varies according to the vigour ofthe constitution; Sir E, Home relates a case inwhich some lymph, effused on the surface of the peritonaeum, becamevascular within twenty-nine hours; but in feeble habits it may requiresome days. Fibrine appears capable of being converted into almost any of the tis-sues of the body; the conversion in any particular case being determinedby the sur
