A two-page internal letter, marked Confidential, from the Medical Department's industrial hygiene engineer to W. N. Johnson of Mining & Metals. It states that the Medical Department did not favor a gravimetric (weight) system for evaluating asbestos, reports a brief King City trial that found no correlation with the count system, and questions the use of "typical" asbestos mixtures and weighing small personal-sampler samples.
