STAINED WITH CARMINE. 



When yeast has been successfully stained with car- 

 mine fluid it forms a beautiful object for investigation, 

 and with the aid of very high powers many points of 

 the greatest interest may be discovered. The cells 

 represented in Fig. 7, plate L, were growing very 

 rapidly. Protrusions or outgrowths are seen pro- 

 jecting from every part of the bioplasm, and in some 

 instances the latter appears to have been preserved 

 while it was in the very act of moving. I have speci- 

 mens of the bioplasm of mucus, of epithelium and of 

 cartilage, which illustrate the same point. In every 

 case the continuity of the bioplasm of the little out- 

 growth with the general mass within the cellulose 

 wall can be well seen. In Fig. 8 are represented some 

 of the smallest and simplest of the yeast particles 

 under a magnifying power of 2,800 diameters, the --$ 

 of an inch object glass. Both these drawings illustrate 

 the mode of formation of germs in this very simple 

 organism, and it will be shown in another part of this 

 work that the bioplasm of man and the higher animals 

 gives off diverticula in much the same manner ; and 

 that these when detached become free bioplasts. 



The diffluent germinal matter within the yeast cell 

 is the material upon which alone all growth and action 

 depend. Were it not for the bioplasm or germinal 

 matter the cell would be lifeless and passive inca- 

 pable of " exciting fermentation " or any change what- 

 ever. Every particle of the bioplasm is living, and 

 may, under favourable circumstances, undergo develop-
