c Mr. Chairman, 1 don't think there ia any great area of difference between the speakers here this morning. I think perhaps some of us hare one or two points of dis agreement with Doctor Sander, but I think that will all be straightened out after we get the record and read it over and discuss it a little more between ourselves. I would only like to emphasize two points. I first came to Saranac in about 1921, If I remember correctlj or possibly *22. Doctor Gardner was then just beginning to get interested In the dust question and I had been working for a year or two on the Public Health Service. I started j in April, 1918 to be exact, and I came up here and we spent ; time in the laboratory doing some foolish things. Among others, we put salicic acid down the nostrils of some guinea pigs to see what happened. Of course, you know what hap pened, most of them drowned, but anyway, one thing that did emerge over the period of years was this, that I've seen a change in our attitude toward many different types of dusts which, at the beginning, we thought were completely inert. At that_time, silica was only supposed to be the only villain in the picture, and I remember the time when the question of talc dust, the effect of talc dust was trousht up end it was said that the pathological effects of respir ation of talc dust were due to three - two or three or f:ur percent of free crystalline silica, and today we know that !
