State University of Iowa, Iowa City, Jan. 18, 1907.
To the Editor:
—My attention has recently been called to a circular issued by the George Leininger Chemical Company, which now goes by the name of the International Chemical Company, in which I am quoted as recommending the George Leininger solidified formaldehyd for fumigation, and in which the State University of Iowa, the Iowa State Board of Health and I personally am mentioned as endorsing the products of this firm. It is true that I have examined the formadehyd mentioned and have found that when used in sufficient quantity (more than is recommended by the firm) and using it under certain conditions (such as a sufficient amount of moisture, a proper temperature, etc.), that it will disinfect. I have never, however, given it an unqualified recommendation and, so far as I know, it has never been endorsed by the Iowa State
