Are these bubbles forming within the section, or intruding from the edges?
If the former, all I can think of is Don Ho and "Tiny Bubbles". It's 
Friday and too few students are worrying about finishing their term 
If the latter: I used to have this problem mounting 50 to 200 micron 
Golgi sections of goldfish brains. The solution was to put a 1/2 to 1 
oz (14 to 28 g, keep it SIU) weight (fishing line weights work well) 
on the coverslip, and add mountant as needed to fill in the bubbles 
from the edge.
