Dear Mary Lou,

We supplied an OTF Cryostat with a Tungsten Carbide tipped knife for a
company located in Cambridge, England for sectioning Bed Rock, they were
looking at the thin sections treated with an additive for Oil exploration.
For those interested I could look into this further if it would be of
assistance.

Best Regards

Dear Histonetters,

A colleague is wanting to see inside soil aggregates of varying
thicknesses, up to several hundred microns. I was able to make paraffin
sections, 20 microns, by soaking the samples in paraffin for many
hours.  No solvents allowed.  A researcher at NASA gets 1 micron sections
from his dust particles in sulfur. We have no idea how he does it.
Thinner is better. Any suggestions out there? Do any bone grinders have any
ideas? Do you know of anybody else we can ask?
Please include Dawit in your responses. Dawit, do you have anything to add?

Thank you very much.
Mary Lou
