Hi Greg,

As a temporary solution you can use a mixture of equal parts of pure
glycerin and distilled water (R.I. 1.397).

For a more permanent aqueous mounting media you could make Kaiser's
Glycerin Jelly (R.I. aprox. 1.47):

Gelatine         10 g
dist. water      60 ml
Pure glycerin    70 ml
Phenol(crystals) 0.25 g

Dissolve gelatine in the water in a beaker placed in water-bath before
adding the glycerin and phenol. When completely mixed, and while still
fluid, decant into small screw-cap jars. For use, melt by placing in
paraffin oven or in warm water. Preparations mounted in glycerin-jelly
should be ringed.

Hope this helps. Katri.
