V. Murdock, Head, Applied Physics Department from the Department of the Ravy, Philadelphia. It would seem that ever}'one has seen it by now but since it s c a n s s o important to all of us, 1 send i^ as a precautionary measure. We certainly will place this subject cn the agenda of the dales Promotion Committee for the June 19th meeting at beuYiew. At tie same time, nay 1 respectfully request that you make the letter available to the JArviromental Study Cocxaittcc vho would also be most vitally concerned. We believe that some form of action should be taken by the Institute in the fora of a protest at the earliest opportunity. Cliff ShecxlcrTs group could certainly advise us in this arc*. At the same time , Kaybestos-Manhattua intends to reply independubly at their invitation as outlined in paragraph 11. We feel it expedient to submit a letter prior to June 15th in order to contribute to discourag ing a development program on substitutes for asbestos in shipboard insulation. lours very truly cc f .-- /,,I Y - V ft-' *r.j .

High ter pere sure insulation, as used by the Navy, must bo cc-poso r.airJ.y of inorganic irntorials in order to endure terpene teres above 20b F for catencci periods. In addition, an acceptable insulation must orhibil the following characteristics: I. Lov: heat conductivity. 2. Non-combustibil ity. 3 Lightweight. 4. Capability of easy rrjoldir.g and application. 5. Moisture rep-ollcncy. 6. Non-corronivc, inroluble and ehcriienlly inert. 7.
