W. J. McConnell of Metropolitan Life to O. H. Cilley on Three Sets of Manheim X-Rays (1939)

A short letter of January 26, 1939, from Dr. W. J. McConnell, assistant medical director of the Metropolitan Life Insurance Company and director of its Industrial Health Section, to O. H. Cilley of the United States Asbestos Division of Raybestos-Manhattan at Manheim, Pennsylvania. Answering Cilley's request of January 10, McConnell attached "a comparison of the findings of the three sets of X-rays of your employees" and wrote that "in the majority of cases there has been no very definite progress of the disease."

What it shows

Metropolitan Life compared the Manheim employees' new films with those taken in 1930 and 1935. McConnell's summary speaks of "progress of the disease" and says only that in most cases it had not clearly advanced; the comparison itself is not in this scan. Dr. Snoke's own reading had found "marked changes" in several men's films (his letter of January 9).
