After ions another short discussion in which e num and answers, the writer tested 14i d'm in an eye concentration test. In the abb've, no outstanding results were achielued but it should be noted for the record that no extensive ef2fort was made-to obtain a -@eep hypnotic state in any of the individuals present. It should also be noted that these new' volunteers all expressed continued interest and a willingness to continue work along these lines. Special Comment: The writer notes that it is considei-abiy difficult to d6h conduct intensive H woi-k with as many as 2 five volunteers in the operatlons room for various reasons. The first is the room is crowded, the second is'the air conditioning unit is not functionina and the air becomes stale with cigarette smoke and tht-- third is that it is difficult to concentrate on one individual at the expense of th8e others present since it is important in this work to maintain the absolute interest of all volunteers present. iAC J" now with the experimentation on 1 December Further in-p_o nec ii twice on the polygral-ii b5, ].'ir. a 5 i-u ---sin anorm pattern f pi itli 2 t experimentation und@r hypnosis as i@hen pu under hypnosis and a card test was run itnder instruct@ion that she Lie tc@' 11 stial@,wstions.
