To the Editor.—  An article that was published in The Journal entitled "Aspergillus Infections in Cancer Patients" purports that the structural steel frame of the Baltimore Cancer Research Center was fireproofed with a cellulosic-based fireproofing material (235:411, 1976). I have made exhaustive inquiries and investigations into this and have determined that the structural frame of this particular edifice was fireproofed with a mineral fiber material and an inorganic binder. Clearly, this is not a cellulosicbased fireproofing material. I think it was rather unfortunate that allegations were made against a material that was not used in this particular hospital.
