Among the chemists who have testified to the purity of the salts entering the composition of Peacock's Bromides, particularly as to its extraordinary freedom from chlorids and the absence of other usual impurities, are names of such eminent men as Edward H. Keiser, Ph. D., professor of Chemistry, Washington University; H. Helbing, F. C. S. and F. W. Passmore, Ph. D., of London, England; Charles E. Caspari, Ph. D., Professor Chemistry, St. Louis College of Pharmacy; and Edward Gudeman, Ph. D., Chicago, Ill.
Thus, when a physician prescribes Peacock's Bromides he has the benefit of Bromide Insurance, as the preparation can be depended on to give the best possible results obtainable from bromides.
Peacock's Bromides is a mixture of bromides of potassium, sodium, ammonium, calcium and lithium, 15 grains combined in each fluid dram and equivalent in dosage to 15 grains of potassium bromide.
