1..The- research detailed in the accompanying letter-proposal is part of the Materials Analysis Project. The work is essentially a change in scope of our present level of effort with this coupany to allow the investigation, i.e., screening of recentlyacquired agents which bold promise of new and unusual behavioral effects.

0 the contractor for this research, has during the past six months (Contract No. screened approximately 137 compounds which more than satisfies their agreed upon performance. However, within the past two weeks approximately 31 new compounds (recently synthesized) were received. These compounds are new analogs series,some and other agents which hold promise as bebavior afiecting agents. In order to evaluate these compounds, our present efort with the 0 zust be enlarged in scope and extended in time.
