Torulce obtained from a Solution of Ammonic Tartrate and Sodic 

 Phosphate. (X 800.) 



both singly and in groups. No other kind of living 

 thing was met with. 



Some of this granular matter with Torulz was 

 mounted as a microscopical specimen, in a mixture 

 of glycerine and carbolic acid (16 : i), and in the course 

 of two weeks it was found that the Torulx had notably 

 increased in size and in number beneath the cemented 

 covering-glass. 



'Experiment 5. A flask containing a solution of 

 ammonic tartrate and sodic phosphate was opened 

 twenty days after it had been hermetically scaled. The 

 reaction of the fluid was then decidedly acid. 



The fluid itself showed no signs of turbidity, and 

 there was no trace of scum on its surface. Small 

 whitish flocculent shreds had, however, been seen at the 

 bottom of the flask for the last twelve or fourteen days, 

 during which time they seemed very slowly to increase 

 in size. Some smaller sedimentary particles were also 

 seen.
