[Histonet] Mounting media to covberslip from ethano

[Paul Bradbury]

I have never encountered a mounting medium that uses alcohol as the 
solvent.

If one exists, two disadvantages spring to mind immediately. One, the 
refractive index of the medium would be low, so the clarity and 
brilliance associated with conventional, xylene-based media would be 
absent. Two, a large proportion of counterstains (eosin, van Gieson, 
neutral red, methylene blue, etc) are alcohol -soluble and would "bleed" 
into the medium.
