THE BEGINNINGS OF LIFE. 



very quickly passed on to different conditions. Their 

 rays became shortened, and large vacuoles appeared and 

 disapp::ared in the interior of corpuscles which were now 

 almost spherical (/). These spherical corpuscles partly 

 transformed themselves into tolerably active Amoebae {^) 

 and partly into rather sluggish Monads(^), provided with 

 a flagellum at each extremity, which, at the time of 

 observation, were mostly vibrating very slowly. 



Five days afterwards the above-named bodies had for 

 the most part disappeared, though the filament then con- 

 tained myriads of ovoid ciliated Infusoria about -^\~' 

 in length, and of the simplest description (7)— closely 

 resembling Dujardin's Enchelys or embryo Pai-amecia. 



Observations of a somewhat similar nature have 

 been detailed by Dr. Braxton Hicks ^, who saw the 

 chlorophyll corpuscles of certain moss-radicles notably 

 increase in size and become cellular, whilst their con- 

 tents divided into three, four, or more motionless 

 segments. The modified corpuscles remained for some 

 months in this condition^ though after this time, when 

 some of them were placed in the sun, the contained
