All were motionless. Gradually, however, 

 they became less refractive, grew more and more 

 vesicular, and at last assumed a faint brown tint.

 others grew and underwent further segmentation, so

immersed in a little syrup upon a glass slip, protected 



by a covering glass, and then set aside in a damp, 



air-tight, developmental chamber. After about ten 



days the germs were found to have become more 



colourless_, to have budded and multiplied, and in many 



cases to have formed elegant mycelial filaments, such 



as are represented in Fig. 595/,/. 



These latter observations are interesting in many 

 respects. It is remarkable, for instance, that germs 

 of precisely the same appearance should arise after such 

 different methods — by origin and growth in a formative 

 membrane in one case, and as the result of the seg-

 that these parental Amoebse had, to all appearance, 

 arisen by a process of Archebiosis, although at one
