Brooklyn, Feb. 14, 1905.
To the Editor:
—Since the publication of my paper on "Indoor Humidity," which you were good enough to review in the columns of The Journal, a firm engaged in the manufacture of a well-known and widely advertised disinfectant, namely, "Platt's Chlorides," has, without my permission, and much to my annoyance, used my name and extracts from my paper in its advertisements. The omission of quotation marks and the clever wording make me appear responsible for recommending that preparation in connection with humidification. I wish to disclaim all responsibility for the use this firm has seen fit to make of the material contained in my paper. I have requested them to discontinue all such references.
