- Monocular estimation of distance. - Difficult without parallax. — Law of corresponding points. — Each ganglion cell two neurons, divide for both retina. - Orientation, with prism. — Diplopia : — physiological at distances farther or nearer than point fixed. — Analogy of digital tactile sense. - Binocular estimation of distance. - Fusing successive double images. — Coördination of convergence and accommodation. - Stereoscopic perspective. Pictures correspond to right and left retinal images. Convergence required to fuse, determines distance; convergence excessive, nearness; convergence slight, distance. — May overcome mathematical perspective. — Binocular vision an acquired faculty. — Fusion training. — The amblyoscope. — Phoro-optometer stereoscope.- Controlled reading

Hypnosis. Phenomena. - Classification, difficult and somewhat arbitrary. — Mild, catalepsy, conclusive evidence of hypnosis. Deep, somnambulism, hallucinations accepted. Catalepsy unwise to exceed at first attempt; sufficient for slight analgesia; sufficient for therapeutic suggestions. Anesthesia not practicable for general surgery, because not absolute in more than ten per cent. - Character and frequency of pulse may be controlled. -Suggestibility increased, raise of threshold. - Amnesia the rule, but subject to suggestion. The alert stage, seemingly inconsistent with sleep. Hallucinations: positive, negative; en rapport with operator, but others may be introduced. — Subject reasons deductively, but not inductively.— Post-hypnotic suggestions; appreciation of time.-Automatism, not absolute, subject may refuse harmless suggestion. Criminal suggestions, popular literature responsible for belief in; mistaken deductions from paper dagger experiment. Refinement of moral sense. — The higher self : avoid being deceived. Precautions in conducting experiments: avoid selfdeception
