The movements of fluids in the artificial cells ” made by Quincke and 
by Bfitschlj are in many ways different from those of living matter. For 
in the latter there may be co-existent streams in opposite directions, 
stoppage and reversal of the streaming also occur. The protoplasmic 
movements are retarded and stopped by cutting off the supply of oxygen, 
therefore they are obviously dependent on metabolism. There are many 
illustrations of vacuolated protoplasm ; often tlje structure is rather that 
of a broken than of a complete network. Frqmework aqd network may 
result from the modification of vacuoles with originally intact walls ; but 
in many cases ttyere is a genuine network.
