lead me to the conclusion that this peculiar action will always 
be found under the above conditions. 
A further fact observed during these studies may here be 
noted, though not connected with the main point of this arti- 
cle. In many cases one or more cells in a filament may be 
found with two bands, while the cells on either side have 
only a single band (Fig. 5). The frequency of occurrence 
of this condition would seem to indicate that the ‘* number 
of bands” in a cell is an unreliable specific character.
