I am enclosing two coples of my concept of the symptomatology of the acute reactlon to diethylamide of lyserglc acid. This concept Is, of course, based entirely on our experiznces at Lexington and will have to be modlfied in view of the experl ences of other people In other environmental situations.

You may be interested to learn that an adainistraflve changc will occur In the hospital on July Ist. Our present Medical Offlcer in Charge, Dr. Kenneth W. Chapman, Is being transferred to Publlc Health Service headquarters in Washington. He will be replaced by Dr. James V. lowry, who currently is in charge of Community Seryices, Natlonal Institute of Mental Health. Dr. Lowry Is a very old frlend of mine and is deeply interested In research: He has, In fact, had considerable research experience himself.

Very sincerely yours,

Harrls Isbell, M.D. Director of Research
