Source passage

Source text · mention only

In default of more complete experiments, I submit the following comparison of Hélène’s muscular force and of her sensibility to pain before and after a seance lasting nearly three hours, the second half being in full somnambulism. At 4.50 o’clock, on sitting down at the table three dynamometric tests with her right hand gave kilos. 27.5, 27, 25—average, 26.5. The sensibility to pain measured on the back of the median phalanx of the index-finger with the algesiometer of Griesbach, gave for the right, grs. 35, 40, 20, 20—average, 29; for the left, 35, 20, 20, 15—average, 22.5 grs. (Sensibility slightly more delicate than that of another lady present at the seance, not a medium and in perfect health.)
