as shown in Fig. 34. These filaments are only 
dimly seen at their origin from the Cocci, in the 
photograph, owing to their being, at this point, 
rather out of focus. 
When this tube was opened and examined again, 
after the six weeks, very many groups of Torulz were 
found in a specimen of the sediment taken therefrom, 
and from the groups of Torula many short hyphze 
were issuing. Several good photographs were ob- 
tained of different groups after they had been stained 
with eosin, one of which is shown in Fig. 35. It seems 
clear that the Torulze seen there, under a lower 
magnification, are just such bodies as were found 
when the tube was first opened (see Fig. 33, A, x 
700). Some of the aggregates of Torule were 
small, but others were much larger, showing that 
they had multiplied considerably before beginning 
to throw out hyphe. In a stained specimen—where 
the cover glass had been surrounded by paraffin—I 
found, when it was examined two days later, that 
some marked specimens of the Mould had grown in- 
the interval, notwithstanding the eosin: the hyphe 
being very distinctly longer than they were when first 
seen. 
274 THE EVOLUTION OF LIFE 
I have already alluded to the changes produced 
by high temperatures on different saline solutions 
(p. 266), and as a sequence it seems well to give 
some illustrations showing something of the effects of 
different degrees of heat upon flakes of silica taken 
from some of the A solution, and when exposed to 
light in tubes of different kinds.
