walls are folded or plaited right and left like the sides of the bellows of an 
accordeon, the plaits being widest at the bottom, or attached ends, and dimin- 
ish outward sala the exposed surface. These cells are somewhat irregular, 
panded and contracted several times before their contents so far disappear as 
to arrest further action.

are so slow as to be disappointing. When the thin section has been brought 
into the field of the high power lens it is well for a neighboring student or 
an assistant to add the drop of water, thus giving the ea. ay the entire
