I. Dreams of animals. — P. shows, through a few cases, their analogy with man's dreams (elective perceptions provoking awakening or integrated in the dream. Role of current concerns, etc.).

A small terrier dog, usually very spoiled, falls asleep after being scolded; after an hour, he starts to whine, then howls miserably in his sleep; shortly after he wakes up, and runs to be petted.

A little one-year-old dog: we put it near her muzzle when she sleeps, a piece of sugar. Without waking up, she runs her tongue over her lips and makes small head movements.

II. Chloroform sleep in flies. — The effect of chloroform translates in two different ways: sometimes there is incoordination, loss balance, disorderly agitation of flies; sometimes numbness motor, sleep interrupted momentarily by excitements a little strong. In both cases, the effect of chloroform on the lymph nodes of the fly results in an intoxication quite similar to drunkenness.
