June 14, 1929 Doctor Fred B. Yishard, Dolco-Bemy 0 o r p ., anderson, Infi. Dear Doctor Wishard: When I was In Muncie several days ago I talked with some of your people about the possibili ty of our finding out something of the magnitude of the exposure in different parts of your storage bat tery plant by means of making various analyses of the excreta of selected individuals* Since I have come back'to the laboratory I have been working on some data that we have obtained on a .group of men under various conditions of exposure, and there are a number of points in our experimental work on which I am very much in need of some additional information, I am especially interested in knowing something of the changes in the rate of excretion of lead and in the amount in the circulating blood where symptoms are occurring, as compared with the same type of exposure in symptomless men. It occurs to me that it might be possible for us to obtain the information that you need and that we need as well, by making a brief study of some of your men. In order for us to do this it would be necessary for either myself or one of my assistants to spend some time at your ffuncie plant in order to get the samples that we need at the time symptoms develop, I should like also to know what happens when sodium thiosulphate is injected Intravenously, and this I am sure we could find out. For the above reasons I am wondering what would be the reaction of your people to our .making: some experimental observations on your men. The " points at issue would be whether or not this would have any bad effect on your employment conditions, and whether you yourself as well as the management would approve. I should be very glad if you would give me your own reaction, as well as that of Mr, Kroeger. It is especially important, it seems to me, that we do this soon if we do It at all for I would like to study the thing under conditions in which actual symptoms are developing. Very sincerely, JSit i' Y A A o , M r* .!
