Dear Nancy,
I suggest you try to get hold of the following book:
Preparation of decalcified sections.  EB Brain.  1966. Publ. Charles 
C Thomas.
This was before ISBN numbers - Library of Congress Catalogue 
Card no. 66-16783.
Details are gived of shrinkages using differant dehydrants and 
clearing agents.  I don't know what's in the quantitation literature, 
but this is as good as anything in LM histology.
If you are stuck, let me have a fax number (or post if you're not in a 
hurry)
