place at the bottom. We made a microscopical exarainatioii 

 of this deposit, a sketch of which we append (Fig. 37). The 

 dark, double-bordered cells are those which were sown but 

 did not rejuvenesce. We may notice in different places several

of these same cells, recognizable by their granular contents, 

 which they are beginning to lose^ to make room for ger- 

 minating cells and joints, often numerous. For instance, in 

 the group at the bottom of our figure one of the cells is in 

 course of rejuvenescence and germination, and has given rise 

 to no fewer than six cells, filaments, or groups of filaments. 

 In different fields of our microscope we met with a crowd of 

 branches, more or less ramified, and chains of cells, of greater 

 or less length, of which we have sketched a few. In propor- 

 tion as the budding of these branches is repeated, the cells 

 and joints become more readily disunited, grow small, and 

 assume the appearance of saccharomyces pastorianus in ordinary
