We have just received----what we regard as reliable"information 
that plain Penicillin "G"......is 95% as effective as Cipro for the early 
control of Anthrax.
            Cipro costs--in some cases----over $250.00 for 250 
ml.....Penicillin  "G" costs about $11.50 for the same amount----at your local 
feed store.
            Sincerely,  Brooks Bradley.
