THE BEGINNINGS OF LIFE, 



intermixed with the small crystals. They were quite 

 motionless, and mostly separate^ rather than in distinct 

 groups. They varied in size from the minutest visible 

 speck, to a spherical nucleated body -grg-Vo-' in diameter. 

 No moving particles or Bacteria were seen. Probably

more than a thousand of these bodies were developing 

 in the one watch-glass— each growing in its own place^ 

 and showing no evidence of multiplication by division 

 or pullulation. In those whose dimensions did not

' in diameter, no nucleus was visible, 

 though the larger of them displayed a distinctly vesicular 

 appearance. As these spores or spore-like bodies in- 

 creased in size, the thick wall became more and more 

 manifest — though it had a rather rough, granular ap- 

 pearance — and a nucleus gradually showed itself within, 

 which was also granular 1. The next morning, after 



^ This appearance I had not unfrequently seen before, where spores 

 resembling these bodies had been developing in saline solutions, and it 

 had always strongly suggested the notion to me that such spores were 

 formed by an actual coalescence of granules and particles. Here, 

 however, there were no granules or moving particles present ; the spore- 

 like bodies were the only possibly living things, and it seemed quite
