Marsha R. Price (where?) notes the article "Mineral oil: the best xylene 
substitute for tissue processing yet" in The Journal of Histotechnology 23, 
143-9, June 2000 - which I also received today. By Rene J. Buesa in the Dept 
of Path & Lab ed at Mount Sinai Med Ctr of Greater Miami in Miami Beach FL. 

This very long article is up to the journal's usual editorial standards. 
Mineral oil, not a simple material chemically, comes in at least three 
commercial "weights" - the article gives no clue that I can find as to what 
kind of mineral oil is meant. I certainly wouldn't advise anybody going out 
and trying mineral oil without calling the author to find out just what 
mineral oil it was that he used.
