August 4# 3. 93^ Dr* F. v/* Porro St. Lawrence County Laboratory A. Barton Hepburn Hospital Ogdensburg, Hew York Dear Dr* Porros I am sending you Herewith the orighmj^_^ cony of our report on the analyses of the tissues of W/ttm 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 Ogdensburg* 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 those 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 purpose. However, I enjoyed very much the privilege of meeting you, and I hope we shall have an opportunity to meet again under different circum stances. Cordially yours* RAX:is Robert A. Kehoe* M.D. Certain tissues* identified by label as these oi were received from Doctor Ferre from the St# Laurence County Laboratory of the A* Barton Hepburn Hospital of Ogdenaburg# Bew York, <m uly 18# 1936# She package was opened by Dr# Kehoe and portions of the tissues were prepared for analysis by removing tbm from the con tainers in which they had been shipped# and introducing them into chemically clean ^&rs0 after shaving off the outside surface of each portion employed as a ample in order to remove any contamination which might have resulted from contact with a lead bearing surface* A ample of the formalin la which the tissues had been preserved oaa filtered free of suspended material and introduced into a small chemically clemcontainer# The unused portions of the organs were preserved in their original containers# Ttso sets of the tissues were prepared as indicated above* One set was delivered to the speotrographlc laboratory* and the other to the chemical analytical laboratory. The weights of the tissues* the quantities of lead found by the application of the two methods# and the calculated quantities per 100 grams of tissue are shown in the following table* K 002195 S N 24372.01 Tissue Liver Lung Heart Spleen weight in Grams 55.6 7U8 2^*8 10*5 Analysis. ......
