The Smithsonian Institution said yesterday that its involvement with the Central Intelligence Agencys MK-ULTRA mind-control program was limited to a review of paper work on two foreign population analyses by an unidentified former research associate.

Documents provided to the Smithsonian by the CIA indicate that the researcher apparently reviewed proposals to study voter patterns in one country during the early 1960s and the relationship between historical events and population characteristics in another country during the dame period.

In both cases, according to the documents, Smithsonian officials were not made aware of the source of the funding for the projects, nor did the insitution take part directly in the studies.

The Smithsonian spokesman said the researcher reported to a research organization which acted at a CIA cover in the MK-ULTRA project. The name of the organization was blacked out in the documents by CIA censors.

Neither of the two countries studied was identified in the documents. However, the voter study refers of its target country as one with a full political spectrum, which the study of population characterists apparently was directed at a Communist-controlled nation.

Despite enthusiastic predictions for what one proponent of the voter analysis called "a unique gold mine" of material, the Smithsonian researcher was only lukewarm in his review of the proposal.

"My own reaction to the project is that it might possibly be considered a little inappropriate for an American foundation to participate in a study of voting in a friendly foreign nation," the researcher wrote.

The CIA told the Smithsonian that there was no other indication of its involvement in MK-ULTRA among the financial records of the program. The Smithsonian was one of 86 research institutes, corporations and universities linked to the mind control project by the recently discovered documents.
