-2- in these values? For instance, it would seem that where 30 micrograms were used as the active source, the net discharge should be 6 times that where 5 micrograms were used, with perhaps slight variations. Page 6, first paragraph: I question whether we should introduce the idea which I get from reading this pagraph, namely - that where weather conditions are not good it might be quite difficult or even impossible to make accurate gamma ray determinations. My position in this matter would be that you can either make determinations or you cannot make determinations, and for those experienced in this type of work they of course, realize that certain precautions must be taken into consideration where weather conditions are not the most favorable. On this basis I would see no objections to stating that such precautions were necessary, but I think we should avoid conveying the idea that there is a possibility of not making precise measurements with bad weather conditions. If you can charge the instrument and properly control the conditions just as precise measurements can be made under unfavorable weather conditions as under favorable. I don't know as I have made the differentiations I have in mind entirely clear, but hope you get the idea. There is one point in the second paragraph of your letter on page 6 which I wish to discuss with Dr. Flinn as my memory in a little rusty regarding accurate values in this connection - that in I was under the impression that the quantity of radium estimated in an individual in approximately the same as the discharge which would be produced by an equal amount of radium as a source, rather then twice that amount. Dr. Flinn can undoubtedly clear up this point for me. On table 111. I note that you have included data with regard to the Lind small chamber electroscope. If you have any data which might be included in table two regarding this particular electroscope, it might be well if same could be included, inasmuch as some of our good friends have made most of their tests with the small chember electroscope. As stated in the first part of my letter, please consider these remarks as suegestions only, for I realize that you and Dr. Flinn have the data much more at hand than I have. Neither do I want you to feel that I am unduely urging you for the completed report on this matial for such was not my intention in writing you my recent letter. I quite agree with the logic of your letter of September 23rd, regard- ing the complete data as to the amounts of radio-active materials contained in excretia of active subjects. However, I have discussed this matter with Dr. Flinn a little further and we both agree that in the particular case in question it seems quite impratical, but we shall endeavor to collect a few specimen which may serve as confirming data for that dready at hand. I am now undertaking the analysis of bone specimens of the Maggia case from various sections of the body to definitely establish whether or not there is any concentration in specific sections. With kind regards, I am Sincerely yours, Vice President.
