So far we have been unable to obtain necessary support to initiate this study. If the present sponsors have no objection, therefore, we will attempt to obtain funds from the government to insure that the work it accomplished. The above change in sponsorship, if successful, would allow 1KF to complete funding of its fibrous dust research program as described in Medical Series, Bulletin No, 11 in addition to the new study designed to identify the central fibers of so-sailed asbestos bodies in humans and experi mental animals, using electron microscopic and microprobe technique*. If there is no objection oti the part of your company to the suggest'on that support for the above IH? project be requested from the U. S. Public Health Service, please sign and return the copy of this letter in order that we may meet the next deadline for submission of cur proposal by April N. a If there should be questions, comment* or suggestions, 1 should appreciate hearing from you. ccTtcb Robert T.
