[Histonet] tissue slicer

[Geoff McAuliffe]

Almost forgot ...........

There is a device called a "Stadie-Riggs tissue slicer" that will slice 
fresh tissue fairly thin, a few hundred microns. Thomas Scientific sells 
them, I don't know if anyone else does. A few hundred dollars in US 
currency, I think.
