Personal observations of Rcrschach tests carried out 1 week prior to LSD administration and during the effect of LSD. (80 mcg. orally). Comparison of the two tests showed that under LSD all personality features were intensified and therefore more readily identifiable. Nevertheless, it would be dangerous to draw conclusions as to the real personality of the subject from the findings in the test, for the toxic factors distort the picture of true hypertrophy of the persona!ity.
