Abex objects to this interrogatory to the extent it purports to seek information or matenals regarding time penods and products that are not at issue m these cases, on the ground that such information or materials lack relevance and are not reasonably calculated to lead to the discovery of admissible evidence To the extent to which it purports to seek information or matenals regarding the working conditions of Abex employees, this interrogatory is also objected to on the grounds that such information or matenals lack relevance to the issues ansrng m these cases and are not reasonably calculated to lead to the discovery of admissible evidence.

Pittsburgh, National Lead & Oil Co. of Pa., 316 Fourth Avenue Philadelphia, John T.

But the compelling reason for my presence at your hearing was my professional concern that the facts concerning lead in relation to the public health night not otherwise come to the attention of the Board of Health.

Abex further objects to this interrogatory on the ground that the information it seeks otherwise lacks relevance to the issues arising in this case, and is not reasonably calculated to lead to the discovery of admissible evidence.

Seer Sr* Kehoe, X hope 70a will not mind my writing: to yon again in connection with the estimetion of blood--Iced* The laboratory staff of the School of Public Health of the University of Sydney hare now become most interested in the problem of estimating the lead concentration in the blood of children suspected of -- or definitely known to hare -- lead poisoning*' " We hare attempted to improvise satisfactory equipment for the collecting of blood samples} bat so far hare not been very, successful* We feel it would perhaps be best to obtain some of the special collecting units, consisting of an evacuated tube and a special needle, as described in the brochure "Methods for Determining Lead in Air and in Biological Materials*, and which are, X imagine, what I hare myself used when X was a resident at the Cincinnati Children*s Hospital* Howcrer, on contacting the local agent of the Beeton, Dickinson Company, X am informed that a special import permit will hare to he secured and that it will not be possible to arrange this before April of this yssr* X sm therefore writing to ask, sir, if you, or one of your staff, would be good enough to let me know the technical name or description of the special collecting unit* X think X shall then be able to arrange for some friend of mine in the H.S.A. to send me out some of the units by sir-mail so that we can get on with the job without too much delay* I must apologise for worrying you again, sin, but shall be most grateful for your help* N22320

We have not taken the trouble to determine the precise nature of the non-volatile lead compounds.

ELECTRICAL HAZARDS perfect bamer against dirt and dampness In fact, some types may become porous with age and absorb dangerous quantities of dirt and moisture In that event, electrical resistance drops to the point that leaking current burns a hole through the insulation to ground Sometimes this drop m insulation resist ance is sudden, especially if the equipment is flooded, but generally the insulation re sistance drops slowly, so that tests can be made, records kept, and failures predicted The megohmmeter can be used to check new electrical equipment delivered to the plant to see whether the electrical insulation meets the manufacturer's specifications or whether it has become damaged while m shipment or has acquired dampness and dirt This factor is especially important in highvoltage equipment To check the insulation of an ordinary alternating- or direct-current motor, the mo tor safety switch is pulled, and one lead of the testing equipment is hooked to the switch blade and the other lead to ground (Fig 31-8) When the megohmmeter is op erated, a small current is sent through and over the surface of the insulation at a rated test voltage (usually 500 or 1,000 volts dc) and the resistance of the insulation m megohms (millions of ohms) can be read from the instrument's scale When the test is completed, all that remains to be done is to remove the test leads and put the motor back into service A few minutes every six months is all the fig. 31-9.

C. with one exception, are lead treated.

Add lead acetate solution.

X think they have been singularly sucoeaefal from the point of view of learning mere about calcium metabolism, and therefore .of lead, end l hop you will be interested in these results.

Kehoe: We have had an inquiry from our Texas affiliate about the sensitivity of cattle to lead and other heavy metals that might be used as pigments in paint.
