Memorandum to Mr. Roeder [A. Roeder], March 18, 1924

3/18/24 Organization Mr. Reeder MAR 19 1924 This is to acknowledge receipt of your memo of the 14th regarding the above subject. 0 I d'o not feel quite as obtimistic about this matter as While you do the in view of aome later developments which have come STATES Life Extension Institute have made a report I do believe that this will satiafy our various operators and that we must wait for Dr. Drinker' final report in or der to really con- vince them that there is no injurious element in our zinc. I believe the should also take steps to secure all information that we oan from Various au thorities regarding possibilities of zine poisoning, or information as to how zine is used in various medical preparations. It seems to me that if we secure this information and publish name in bulletin form it would help material to counter- aet statements made by various dentiats and physician 8 to some of our operators.

There is also another operator who left us at Christmas time and who is having some trouble wi th an infection of the jaw, which is attributed to zine. In the Life Extension report for Miss Smith and Mrs. Maillefer the condition of their teeth was commented upon and rec ommen dations were made that some of the teeth should be re- moved. Miss Smith, and I believe Mrs. Maillefer, have both been informed by Drs. Davidson and Barry that they should not have their teeth taken care of, or these particular dentists would not take oare of them as long as they remain in our employ. It is statements of this kind which keep up the unrest and anziety of our operators and it is this that we must. onunteract with re- por ts or authentic information from individuals who can be con- sidered reliable. We have increased our application force with the ad- dition of six painters but sooner or later this general impression as to poisoning, etc. will be broadcast and further anrest no doubt will be the result. I do not feel that we have finished this whole proposi- tion, that we must be continually on the alert to get whatever in- formation we can and present it so that our operators will fully understand and believe that when we state that our work is harmless that it is so, and that the mere fact that poor teeth conditions are coincident wi th their employ here and not the result of having been in contact with our zine material. I believe it would be a very good plant to submit some of our new operators, when we finally decide on those whom we be-
