Stockholm, Hay 21, 196U By air mail The Kettering Laboratory College of Medicine University of Cincinnati CINCINNATI Ohio U.S.A. Deah Sirs, I have been told that an investigation - orobably sponsored by the CARBORUNDUM CO - has been made at your laboratory in 1963, concerning the problems of hygienic and medical risks by using bakelitebound grinding wheels with resinoid fillers, specially such additive materials as Lead, Antimony, Cryolite. Could you please tell me where the results of this investigation are published - or, if possible - rather send me a report-copy or a brief summery of it. I understand that it will mean a little bit of extra work to you, but I should appreciate very much if you could help me as soon as possibly. Yours faithfully, /a*) Mr 0 .
