To the Editor:  —In The Journal, July 5, 1924, appeared a description under my name of a lacrimal needle and punctum dilator combined. This article failed to mention that Dr. Carl Koller of New York had previously devised a lacrimal needle with a solid tip and lateral fenestration, which admirable features I had incorporated in the needle underDr. Koller has just called my attention to this omission (not of my making, for if you consult your files I am sure you will find my original report mentioned this fact) and though in every other feature the Tenner needle differs from the one devised by Dr. Koller, in all justice to the latter, due credit and acknowledgment should be given to him.
