SYNOPSIS. Polyvinyl alcohol has been successfully substituted for natural gums in water‐miscible mounting media of refractive index 1.38. Two gm. of polyvinyl alcohol is dispersed in 7 ml. of 70% acetone into which 5 ml. each of water, glycerine and lactic acid are then stirred. A further 5 ml. of water is added slowly and the whole is heated to transparency. The media dry rapidly to a hard pellicle.
