Hi, Barbara

I'm forwarding the query to  Greg Higby,  American Institute of the 
History of Pharmacy. "History" <[log in to unmask]>

My knowledge of chemistry is laughably small, but I think 
"perchlorate" by itself is meaningless unless you know what other 
elements are in the perchlorate molecule.

For the animal feed--try the National Library of Agriculture in Beltsville MD.

All best,

Karen
(very happy to be able to give back a little for all the information 
you provide!)
