Dear Doctor Smith Confirming our phone conversation I should like to describe the research effort to be carried out by our Department relating to the detection of asbestos bodies in animals not exposed to asbestos Specifically over the past five years approximately 3,000 animals have been sacrificed and tissue specimens preserved for microscopic study Approximately half of these animals have breathed outside air somewhat enriched in automotive exhaust products while the other half have never breathed air containing particulate matter It appears that it will be necessary to cut thicker sections then have already been cut and accordingly a representative number of animals tissue will be so treated These thick sections will then be scrutinized to determine whether or not asbestos bodies are present As a corrolary study particulate matter which was removed from the air by filtration will be examined to determine whether or not asbestos fibers can be identified We recognize of course certain experimental difficulties which may render it nearly impossible to be certain of the presence or absence of fibers and will welcome any technical guidance which your laboratories may offer In this connection we are sending a sample of atmospheric dust and will be interested in your findings Although it is difficult to estimate the expenses is PRODUCED the opinion of Dr. Vorwald and myself that approximately 7,000.0 7,000.0 PRODUCPERDODUCED will be required In the event that the findings are sufficinatly PRODUCED interesting and we mutually agree that even more work is required PRODUCEPDRODUCED it is our understanding that you would favorably consider additional PRODUCED Dr. K.

The travel schedule seemed to be too arduous so it was recommended that Dr. Cartier should go to Vienna and that I should represent the QAMA at the Tokyo and associated meetings As requested and accompanied by my wife Marjoric I went to Tokyo for the international con- pathology ference and attended associated meetings on pulmonary physiology and at other centers __ I obtained travel expense money from Johns Manville and submitted my expense account to Karl Lindell and the QAMA in December 1966. This was thoroughly discussed in the presence of Dr. Cartier Mr. Ivan Sabourin Dr. John Beattie at our meeting when I reported December 17 1966 at the hotel in New York Subsequently our paths diverged and it appeared there was some confusion about the authority to use the funds for travel to the Orient Now after many months of reflection I feel that I must submit my statement for expenses incurred in the name of the Quebec Asbestos Mining Association I plan to do this but first would appreciate your feeling on the method of doing you always have been elose friend and good confidant so am seeking any suggestions or advice before submitting my statement to the QAMA do not wish to cause any embarassment to you whatsoever because of our past association , Sincerely Ken W.
