I was delighted to hear that you are going to work with Owens-Corning on their glass-^rool problem, along the lines that we disoussed at Remark. I think this is one of the finest steps that the glass-wool business has taken* In his letter of April 26 to you, Carl Staelln asked me to send you what dnst counts we had available, taken at the Newark operations* He took dnst samples at Remark on three occasions t November, 1934> February,1936 and lowmber, 1936. Saaples were taken with the Oreenburg-SWith impinger, as modified by Batoh, and were counted with light-field illiaalnation at the magnification of about loaz. On the first and third visits, distilled water was used as the eempliag liquid, so. that the dost counts represent water in soluble material. On the eeoond visit, methanol was used as the sampling liquid in ooneeotrations varying from 100 to 60%, the dil uent being distilled water. The following are the dust counts expressed in millions of partioles per aubio footi Sampling Point Length of Sample (Kin*) Dust Concentration (Millions per ou.ft.)
