Alcohol and formaldehyde (formalin--HOCH/methanol mixture) were the most common.  Almost 100% alcohol was used by Darwin to collect his samples and the Brit Museum has that whole vast collection with fire suppression heads at about every 4 feet to deal with the fire hazard.  Formalin and other formaldehyde mixtures came in full swing in the 1930s. 
 
Take a look if the department also has an old glass microscope slide collection from the 1940-1070s.  These specimens were either covered in balsam or Arochlor 1254 (PCBs).  They can cost a lot to get rid of as well.
 
In museum work, Arochlor 1254 had an exemption for use as a slide mounting medium until around 1990.

Subject: [DCHAS-L] Biology Specimen Disposal

Hi All,
 
We are cleaning out and remodeling our biology lab and have LOTS of preserved specimens, some from as far back as the  1940's.  The biology folks want to discard these.  My question-is there any way to dispose of them other than through a hazardous waste facility?  I assume most are stored in formaldehyde solution.
 
Thanks in advance for your wisdom and replies.
