[Histonet] periodic acid/h&e

[ewj <@t> pigsqq.org]

Thanks for the tip.  I had some periodic acid so I tried a 2 minute soak in a 0.5% soln of that followed by a tap water wash and then dw then Harris hematoxylin countered with a Eosin-Biebrich scarlet we like on some classical swine fever slides I looked at today. Very nice.  I will play with this more.

By the way, We use the hot water/detergent method for all our dewaxing now. 

We still are using xylene and alcohols for our processing from fixative to paraffin but
we will change that eventually.
