The discovery of the aluminum hydroxide technique by the Kopeloff's¹ was a fundamental advance in this regard. Local injection or application of alumina (aluminum oxide) cream will produce a chronically discharging lesion with fair regularity. However establishment of such a focus requires from six weeks to three months to develop. Once established, it may persist for at least two to three years.

Some years before this, Speranskii,² and more recently, in a better controlled fashion, Keith and Bickford,³ had experimented with local cortical freezing.
