Your assistance in finding a replacement for Dr. Knudsen will be appreciated, Ideally such a replacement should participate in the survey but at least should be available the first part of the summer to overlap with Knudsen in the Marshalls before he leaves in September, Such a doctor mist be motivated for the type of challenge he will face. He should have some background in either general practice, surgery or perhaps pediatrics. internal medicine, Time will likely be available to carry on epidemiological or medical research of his own choosing. Salary will be negotiable. He will be entitled to tax free income if he stay 18 or more months. Air conditioned quarters at Kwajalein will be furnished. Sho.id you feel that a meeting of the doctors participating in the survey would be advantazeous please let me know. At any rate I will appreciate comments and suggestions as soon as possible. Time is growing short, Robert A. Conard, M.0.
