Letters Received to H.H. Barker, October 22, 1928

UNIVERSITY OF MISSOURI COLUMBIA OCT 241928 DEPARTMENT OF CHEMISTRY October 22, 1928 Mr. H. H. Barker United StatesRad ium Corporation 535 Pearl Street New York My dear Howard: I am enclosing herewith the revised transcript of our paper ready for the publisher. The entire paper has been rewritten and we are enclosing an extra two copies, one for yourself and one for Dr. Flinn. I have on hand another copy. You will note that in returning this re- vised copy that I have incorporated practically all of the suggestions which you and Dr. Flinn have submitted in your letter of October 20. I agfee with you that the omission of the outline will improve the paper. Referring to your remark about the rate of transforma- tion on page 16, line 5, of the old manuscript, the rate given, 18 per cent I think is correct and it is Obtained by multiplying the number 2.09 X 10-6 first by 60, which would give the constant per minute, then again by 60, the constant per hour, and finally by 24, the transformation 18 per cent. You will note that I say that it is being transformed 18 arthr per cent per day which amounts to an accumulation of about 16 and 1/2 per raky cent, but I think the expression as we have it there is the one generally given. ( See page 81 of your bulletin on Radium Extraction) In reading over the paper you will please note that I have made several small changes in rewording which I hope you will find are in most cases improvements. In looking over the last issue of Chemical Abstract, I observe that papers similar in character to ours appeared in a journal known as Radiology. I must confess, however, that I do not know about the standing of these journals, and I shall therefore leave the entire matter of securing a publisher in the hands of you and Dr. Flinn. It is quite immaterial to me where the paper will be published. It seems to me that our main objective at this time is to secure speedy publication. With very kind regards to both you and Dr. Flinn, I rema in Sincerely yours, Herman Schlundt Herman Schlundt. HS c b
