Dear HISTARCH,

My apologies for resending this.  I had forgotten to change the
subject of my previous email, which may cause it to go unnoticed.

I am trying to find any publications on soap making in the 
historic period, particularly anything dealing with faunal 
remains.  From my understanding, fats used in soap production 
would have been more likely to use subcutaneous fats like lard. 
I am trying to address an anonymous claim that bones would have 
been boiled for grease to make soap, but I am not familiar with 
such research.

Thanks to Bob Skiles for the incredible reference, and any more 
would be appreciated.

Thanks, Adam Heinrich
