Confidential internal letter from the Medical Department's industrial hygiene engineer to W. N. Johnson of Mining & Metals about using a gravimetric (weight) system to evaluate asbestos. It reports that a brief trial at King City found no correlation with the count system, questions the use of 'typical' mixtures and weighing of small personal-sampler samples, and says the company was still looking for a better fiber evaluation system.
