The Saranac Laboratory FOR THE STUDY OF TUBERCULOSIS OF THE EDWAlO L TRUDEAU FOUNDATION Saranac Late, N.Y. February 24, 1943 Hr. Vandiver Erovm Johns-V.anville Corporation 22 East 40th Street New York, New York Dear Mr. Brown: .` I have at last succeeded in analyzing nost of our . vdSSStLnous experimental data end assessing the results. I realize 'ltai; this should have been oompleted before this, but the emergency haa left me short-handed in the Laboratory and also necessitated ny doing a good deal of extra traveling. -I hope that the sponsors of - our study of asbestosis will be oharitable and realize that the work has far exceeded its original scope. . Ve have done over 40 different ..experiments, many of then .divided.'into several parts, which involved .exposure of animals for 1 to 3 years to various dusts. The business of. preparing micro scopic sections and chemically analyzing the tissues on more than jgj 00 animals has been a Job .in itself- lay tIhp .for studying sections and analyzing data hgn been so limited "that we are behind our sched ule- T have still not had time to write a full report of this work which will of necessity be monographic. However, for the benefit of the contributors, 1 am submitting a table of contents and an an rV*. notated outline to indicate conclusions and the line of argument that will be developed.- The latter ltaelf occupies 15 pages, but I hope they will find it sufficiently interesting to read. I shall work on the final manuscript as I have'opportunity. There are a -'few. experiments still in progress which should be completed by the time ve are ready for then, ^he work on methods.of dust determination, I consider important enough to in clude in the study. The question of cancer susceptibility now seecs more significant than I had previously imagined. I believe I can obtain support for repeating it from the cancer research group. As it will take two or three years to complete such, a study, I believe it would better be omitted from, the present report. If it should become possible to make this study, I hope that I any count on some of your members to supply me with enough pure, long fibre asbestos for the purpose. : '? -<ci ~ PLAINTIFF'S I EXHIBIT 060 06 00091 Hr.
