Bert, 
I read your message, but I don't think it is Jenner's stain because in
the procedure, Jenner's Stain is used in the step preceding this mystery
concoction. Like I said before, I think this is the actual formulation
for Giemsa stain.  I found the exact same recipe in a 1947 edition of RD
Lillie's Histochemistry techniques under "Giemsa stain" and he describes
how to make up the Giemsa stain.  Thus, I am left with skipping this old
version and making up giemsa stain from my good new stuff from Sigma.

thanks, anyway, bert!  
gotta run
