SUDjECT:E"Flastic"

1. Fron a rerusal of the dccuzents,dealing with "Plastic," arà discussions on Sonterber 9, 1952 vith Eessrs. kaere, this bricfly is te proscnt status:

Thus far, no potent substance cr substances have boan identifisd in any of the aalyses to which the centainers ani their ccntonts have bean subjectod. lo psychocherical agent has besn foud wiicz, upon injccticn into any part of the tody, risht, es suczcoted, "zszier the victin aronable to guidance of his captor for en iniefinits.tis and night evon enable hin to valk erect and shcv no sviience of nircosis." The nain reeson for this failure is the extreze scarcity of natsrisl now left for analysis. Other reascns for the Tery s\_ev progress ea:

à. the lack of knoulodge of naturel cr snthetie substancss or rixtures with the exect psycholcgical and pysiolosica affects upon hzen bokavior indicated.

b. lack of data of phosical charactsristics of Fspehocheriosl substances for crparison and guidencs.

é. scarcity of ricrochenical tests for these asezts.

d. general unfanilierity,vith ricrophysiclogicel sereening tests.

2. Results of previous exnihations are às follous:

a. Plastic Container

According toes
Ws- the plastic Was icontified as poljmsthyl netacrylate," probably renufactured in Cernany, (Razhn and Hass, Darastadt, W. Gernany). It is bolieved tho containers ccui have beon prcduced froa this plastic resin in E. Gerrary, is well as in the USSR.

Chericcl Chsrocteristics:

The belicf has been expressed by Dr.(as related by lr.Yped Ir.   that the erystals are likely of an ergamie naturo and that pessisly nitrogen is lresent. The substance or substances thus ray have the character of an elkaloid. lo nicrocharical tests have been made and apparently caly fev pro avoilctle.
