It seems possible that l will have fo go to New. York on September l9th to appear before the Senate Subcommlttee concerning narcotic addiction. Hearing dates are September 19-2l, 1955. I have been told that 1 will probably appear on elther the 19th or 20th.

This means that I could be in Washington on September 20th or 2ist. If you or somecne else will-be available on September 20th or 2lst 1 should. like to stop in Washington for s briefaconference concerning our work here.

Experiments with the mlxture of Hyoscine and LSD are fairly well along. As soon as the data are analyzed I will send them along.

Yours very sincerely,

Harris Isbell,M.D. Director of Research
