August 4# 3. 936 Dr. F. W* Porro St. Lawrence County Laboratory A. Barton Hepburn Hospital Ogdensburg, He York Dear Dr* Porro: I am sending you herewith the o r i g i n a ^ ^ ^ ^ cony of our report on the analyses of the tissues of B H B B B B ^ which you were good enough to send me some days ago* I am retaining the other copies of this report* pending any comments which you may wish to make* If you are agreeable* I should like at a later date to 3end a copy of this report to Hr* Maxwell whoa you will remember a3 one of the attorneys who talked with you in Qgdenaburg* You will note that the formalin was apparently not sufficiently contaminated with lead to make any significant difference in the analytical results* It is also quite apparent from these results that the embalming fluid could not have contaminated the tissues significantly* I think it may be accepted that there were no abnormal quantities of load in the tissues of this man* and I do not believe one would be justified in exhuming the body for the sake of obtaining samples of bone or other tissues for further analyses* However* if it should be concluded that this is desirable* I should be very happy to make such other analyses as will be required* You will be interested in knowing that these tissues did not contain abnormal quantities of bismuth* On the other hand* the lung* because of.its very deep congestion, contained unusual quantities of iron* while the liver, particularly* showed rather more copper than is common in our experience* Allow me to thank you for your courtesy and cooperation in letting me have these tissues* I am not looking forward especially to a second appearance in this case* and I have no wish to return to Ogdensburg for that purposs. However, I enjoyed very much the privilege of meeting you, and I hope we shall have an opportunity to meet again under different clrcumstances. Cordially yours* RAKjls Robert" A. Kehoe, M.
