At the Second Parathyroid conference held at Noordwijk in August 1964, Talmage (in press) who had already demonstrated that the removal of hydroxyproline from bone followed a pattern quite similar to that of the mineral components (Talmage, 1962), reported that numerous enlarged osteocytes were observed early in bone fragments cultured with parathormone. 2. Electron microscopy of bone cells of the chick Further aspects of this osteocytic activity have been uncovered by electron micro- scopy during the past year. Very intense osteolysis has already been observed in the bones of young chicks (Belanger et oil., 1963 b). This type of material being not too hard, can be processed for electron microscopy with a minimum of ^|, I ^ above.
