[Histonet] formaline 40% with crystals at the bottom

[Jay Lundgren]

Cover it loosely, and warm it up a little with a stir bar, under a hood.
You should be able to tell the difference between alcoholic and aqueous
formalin by smell.  Why isn't it labelled?

                                                            Sincerely,
                                                                   Jay A.
