SEVAN, MANAGING DIRECTOR OUR REF. HF/MB* YOUR REF. 27th September, 1939. Dr. R.A. Kehoe, (Dept, of Physiology), College of Medicine, University of Cincinnati, Cincinnati, Ohio, U.S.A. Dear Dr. Kehoe, I wish to refer to my letter of the 26th Jiuly last in which I referred to an instrument 'which I saw in the course of development in the laboratories of tl e Cambridge Instrument Co. 'Ltd. for determination of very small concentrations of metsl^ in solution. The Cambridge Co. have just sent me a leaflet they have published which describes this apparatus, and I am .ending this on to you in case you may be interested. In acknowledging this to the Cambridge Co.' I have asked them specifically whether they have undertaken any work on aisolution of - organic metalli c compounds, and' if I can obtain, any moreiconcrete data from them I vtall pass it on to you. Yours very truly, P.S. The Cambridge Company offer, in sending us this information, to aarry out tests on specific sjamples. If you would care to avail yourself ' of their offer perhaps ;you could prepare several standard samples -to act as comparisons and then several test s amples the concentration or which would be unknown to them in order t get them to check back on these.
