For want of a better title I have given the name of "brazier's disease" to the syndrome about to be briefly described. The literature contains articles dealing with acute brass-poisoning, brass chills, brass-founder's ague, fièvre des fondeurs, Staubfieber and Giessfieber, all of which refer to the same symptom-complex. The symptoms are characteristic of acute brass-poisoning or zinc poisoning and occur only in workers who have to deal with molten zinc or brass in foundries. Brass is an alloy of copper and zinc in varying proportions. Until recently only founders were exposed to these fumes, but the modern development of industrial science, the intensive development of every known mechanical device has automatically created new vocations and given rise to diseases not hitherto encountered. The perfection of the acetylene-oxygen torch has led to a marvelous degree of autogenous welding and has remarkably facilitated the art of brazing; but from this "brazier's disease"
