Dear All,

	From my notes on museum preparation I found the following methods (some
rather historical!) for mummified tissues:

	1:  Soak in a saturated sol'n of sodium tribasic phosphate at 50C for at
least 8 hours, perhaps several days.

	2:  Soak in 50% polyethylene glycol.

	3:  If badly dried, soak in 1-3% KOH, the process must be watched carefully.

	4:  Armond Ruffer Technique
	Soak in 3:5:2 Ethanol:Water:5% Soda solution, to restore to original texture.

	For museum mounting the tissue is mounted in 10-15% glycerin or
polyethylene glycol - as this softens the tissue.	

	Regards

	Rob W.
