(Skip Step 6 if you are using an HCGSN without sponge inserts. You perform
this step later, after filling the pedestal with electrolyte formulation, which is
described on page 74.)

some cases, such as for subjects with unusually thick hair, a pipette or eye
dropper can help displace hair from under the sponge. If a sponge is unusually
