; May 3, 1943 1 'l ' * I it * * * Mr. Philip Drinker# i; , - Los Angeles# California. (To he delivered by D r . R . T . Johnstone) ' Dear P*---hil* ** ^ irrv *0" * 1 * ' I am sending yon herewith the mimeographed copy of Cholak*s report about which ve talked last Friday. X seem to remember that it is necessary to supply your printer with a typewritten manuscript, but before retyping this I think it will save trouble all the way round if you will look it over, making any notations and giving any suggestions you may have for the modifications that seem satisfactory to you. If then you will return the report to me, we shall revamp it as you wish and forward it to you. If it is satisfactory in its present form, I shall have nothing more to say, but this hardly seems likely. - With respect to the matter of analyses which ve briefly dis cussed# I have just talked with Cholak about what we can do to be of some help to you. In order that there will be no undue delay on our part, I am ordering additional containers and needles. We shall need the needles in any case before ve are out of this trouble# and despite the additional invest ment of about $150.00# I am going to have them on hand. We could just about double our analytical facilities by extending or adding to one or tvo of our chemical hoods and by training one or two additional people to help us at crucial points. If you are quite serious about wanting the analyses# ve perhaps ought to get ready so that we shall not have to upset other necessary work when you come to us with this. Consequently,' I would appreciate it very much If you could give us some idea of what If anything you will require of u s . If ve are given a little advance notice, we could come through with any reason able amount of assistance. There is one matter in this connection that I ought to warn you about. The collection of samples for this purpose Is a difficult job that takes careful planning and careful execution. Unless you have had experience with this, I am sure you will not realize hov great are the opportunities for contaminating samples to such an extent as to give useless and altogether mis leading results. I am quite sure that we shall be able to get satisfactory samples vlth the assistance of the doctors# but in order to do so we shall have to convince the doctors of the necessity of faultless technique. Otherwise, we shall all be vast ing our time. I am sure that very few people appreciate the seriousness of these difficulties# and therefore# I am empha sizing the point at the risk of boring you. The real difficulty
