To the Editor:
—The making of punctures, exploratory and otherwise, through terebrated, instead of trephine openings, as described by Dr. Edmond Souchon, and referred to in your editorial of September 7th, is not new in any sense. It was carried out by me and its results described several years ago.1 I have never claimed originality for it, as Gibier, if I remember rightly, employed terebration ten years ago, in the course of some inoculation experiments involving the brain. The apparatus used by me was an ordinary watchmaker's drill.Respectfully yours,712 Lexington Ave., New York, Sept. 7, 1889.
