Vacuolar system. 1-3, vitally stained with neutral red; reticulate, tending to fuse into a vacuolar canal. 4-6, Bensley's method; system appears as canaliculi of Holmgren. 7, 8, da Fano's silver impregnation method; system impregnated with silver, resembles Golgi's network. 9, 10, Kolatchev's osmic impregnation method: system strongly blackened. cellular differentiation this network swells and is transformed into small spherical vacuoles, each containing a precipitate heavily blackened by the silver and often arranged as a crescent on the bor- der of the vacuoles, thus appearing like the Golgi elements or dic- tyosomes. Finally, in differentiated regions, the vacuoles are seen to swell and run together to form large vacuoles containing a more or less large number of corpuscles, blackened by a deposit of metal- lic silver. There are, therefore, obtained with silver methods, images which can be perfectly superimposed on those furnished by vital staining with neutral red. By means of these methods of impregnation, metallic silver is deposited on the filamentous and reticulate elements of the vacu-.
