However, we question the advisability of making the initial contact as high up as the Director of N10SH. Zt would seem more appropriate to us to have a couple members who have been active In our Technical Task Croup, one of whoa should be competent to go Into detail regarding the known toxicology and the planned studies, visit Dr. Herbert Stocklnger as bead of the HIOSH Toxicology Laboratory and also of the TLV Connlttee.

Zf Dr. Stocklnger feels that we should go higher then we would be obligated. Our contact with Stocklnger should not be a casual discussion at a meeting.
