nective tissue, wMch,, according to Virchow, is a cell 

 with all its essential constituents (cell-wall, cell con- 

 tents, and nucleus), and not a nucleus alone, as origi- 

 nally described by Schwann, and later by Henle* and 

 Landois.t From the well-known universal preva- 

 lence of connective tissue, this view receives support. 

 Thus, it is from the connective tissue corpuscles of 

 the soft, silk-like connective tissue, so universally 

 present in muscle, that the muscular fasciculi are 

 primarily developed. It is from these that^^nerve-

 tion of these corpuscles that pus is formed (Figs.
