i 1 Mcy 29, 1950 Mr. . 0. tiasard Industrial Relations Division Owens-Illinois Glass Coapany Toledo 1, Ohio Rat Our ltr Fab. 21, 1950 lour ltr War. 7. 1950 Dear Bill* This is asrsly to brine tho aattar outlinad below to con clusion. is you recall, the reference letter was preaptod by our in quiry conearning a possible chance in the aaaufaeturlnf process of Xaylo to account for the shorter fibers present in a recent batch shipped to us for our investigations. Our records show that ve received a batch of laylo, January 1947. This lasted until Septeaber 1949 at i&ich tlae we started dustinf with another beten vhieh had beaa received in January 1949* This lattsr pro ,duct is the saterial to which reference wee aade in our letter of February 24 1950, to you* The fact that in reseat aontha you have aore effectively separated end spiculated the ehrySotlle fibers would account for the differences noted by us* Flea our point of slew, probably the eoat important result of this difference is the fact that it is now possible to produce a hifhsr concentration of dust in our experimental roca than was possible with earlier products, During the peat masher of aontha we have endeavored to hold this concen tration down to an average of 300 Billion particles per cubic foot of air* .:'t 'J Sine# the fibers are shorter and seea lees flexible, Z do not believe they are sufficiently numerous to change the type of tiaras response to dust of the first batch* However, in view of the findings it night be well to exaaine a snail saaple of a current bateh of the material. This is Just to bs on the safe side. AJYibw cc: Dr. Shook Sincerely yours Arthur J. Vorvald, m.D, Director 000120 7^ lA !,/ Asbestos Litig Saranac Lake 1989 Depos. Exhibit p.99
