IN the article on “Microkinematography” in NATURE of December 14, 1911, there are one or two points which are expressed in a manner that may lead to misconception. Dealing with these as they occur, is it correct to describe the process as having been developed during the last few months? The method adopted by M. Comandon was described in La Nature so long ago as November, 1909, and reproductions of kinematograph films were used to illustrate the paper. In this country, too, Dr. Spitta has done and has exhibited numerous examples, and I believe I am right in stating that his work extends back to an even earlier date.
