V' July 9, 1958 Mr. Fred M. Younger Younger Laboratories 5o20 Telegraph Road St. Louis 23, Missouri Dear Fred: We are sending under separate cover a sample of OS-95 for the following toxicity tests: (1) Skin Absorption MLD (Rabbits) (2) Skin Irritation (Rabbits) In the work you did on this material in January and February (Y-58-4), the Minimum Lethal Dose on skin ab sorption was lower than we would anticipate from the components of the fluid. In connection with the skin Irritation, if the scores are as high this time a3 before I think we may have to recommend avoidance of repeated and prolonged skin contact In handling the fluid. As you know, a data sheet on this material was submitted to you with the first sample. This will be Project No. Y-58-29. Very truly yours. EPW:dh Elmer P. Wheeler Assistant Director Medical Department DSW 586288 STLCOPCB4091622
