X do not like to be peremtory about these matters but our efforts and yours may be not only ineffectual but may even lead to actual dis tortion of the true situation if our requirements are not satisfied.

Actually, the letter received from the Assistant General Manager at Tsumeb, which should have been quoted in our letter to you of August 1st, is as follows: "It is our intention to select two men from the Germanium Plant, two men from the Copper Smelter and four men from the Lead Smelter when it goes into operation, for thorough checking of lead intake by blood analyses.

I can tell you, however, that my clinical associates (such as Henry Ryd<a: and Bill Ashe, for example) have examined the eyegrounds in quite a series of frank cases of lead poisoning, without observing any such phenomena.

This needs to be resolved more than the challenge that urine ALA's frequently fail to identify persons with high blood lead levels.

At present I cannot offer any Ideas for a program leading to this objective. 2.

Lead poisoning - continuous test program in operation.

Lead poisoning - continuous test program in operation.

A survey of the lead hazard in indoor firing ranges is given in Abst.

I hope that all is well and that the previously increasing levels of lead in the urine of the workmen, generally, have stabilized, as I expected them to do.
