/ March 12, 194? Dr. Roy C * A. Boclc, Remington Arms Company, Inc*, Kings Mills, Ohio. Dear Dr. Bock: I am sending you herewith a report giving the results ob tained on the eight additional men* A few comments on these results seem to he amply justified. I have gone over the information contained In your letter and recorded on the examinet iq il j i&c ords . Let me remind you first that X have no data B^^Bl will he useful to have the additionaJ^nrorma11o!W^^our convenience. It is quite apparent that there are certain spots of significant exposure in your Shot lover. I have a limited familiarity with the operations in such a plant and I recognize that the opportunities for lead exposure may vary considerably with the different occupations^^n^s armarent that the character of the work done byfH^|B and is of a hazardous type. The fact that ths~ results `entire same for all practical purposes on these two men is sufficient evidence on this score. The results on Morris are also quite high and they indicate the advisability of looking Into the exposure in connection with his work. If we assume that he has had no prior exposure to lead, he must have had a rather heavy exposure since entering upon his present work. The same comment^arf^^^t^ied to a some what lesser degree in the case of^^^^^^^^BB The re sults on the blood of BBB^uidB^^BK are essen tially the same, but tnere I^conStderabi^vSrWtlon in the urinary values on these men, a circumstance which may have resulted from considerable variation in their intake short^^J^^m^Jjhe samples were taken. The urine sample fron^B^B|^^^B must certainly have been quite dilute. MB|Ban<^^^^B have apparentljMiad very little exposure. ^n^rEidlng^H^he blood of ^BBftare somewhat above normal levels and are indicative of IHSWRight exposure. On point In the interpretation of these results Is the actual length of time they have been on the job. Your comments Indicate that several of the men are new employees, but it is Important to-'know what you mean by that statement. That is to say, I should know whether they have been exposed a few days, a few weeks, or a few months. Any change which might take place In the blood levels within a few days would be very signifi cant , but if it developed only over a period of months, It Dr. Roy C. A.

Also, the exact date on which anyone of the men moved from one joh to another would also he significant. After examining these data yourself, you may have some question in your mind concerning their significance in relation to other facts which you may have concerning the work of these men and the care they take in protecting themselves against exposure. I should he glad to give you any help X can in the further in terpretation of the results to your practical advantage. Just for the sake of the greater convenience to ourselves, I am enclosing herewith an additional invoice to cover the cost of these sixteen additional analyses. Cordially yours. RAK ef Enc.
