Experiment m 



Some of the same solution as was 



microsco 



employed in the last experiment, similarly exposed 

 and rendered similarly fluorescent. After the exposure 

 to sunlight, however, the tube was kept in ordinary 

 daylight for two weeks, so that it was not opened till 

 the commencement of the ninth week. 



It was then found that the vacuum was impaired as 

 in the last experiment. On 

 of the sediment the same kind of granules (separate and 

 aggregated) were seen, and also great multitudes of the 

 Desmid-like organisms. These existed more abundantly 

 than in the last solution. Here also there was the 

 same fresh appearance of some^ and faded look of others 

 and also great variations in size — the largest being 



in length, whilst many were not more than 



1500 



joVf'' in length. Several groups of four were seen, in 



Fig. 35.
