This is a contribution to the psychophysiology of the newborn by means of exact laboratory experiments. Contrary to the older methods of study which made use of the infant's behavior as indicative of pleasure or pain, the author utilizes the differences in the cerebral pulsations and the respiratory curves which occur as a result of various stimuli on the senses, and makes graphic records of these. To prove that a mere look at the child is not sufficient to indicate the inner workings of its primitive psyche, Canestrini cites the following experience: He had occasion to observe a sleeping infant react to acoustic stimuli (the blowing of a trumpet) by an increase in cerebral pulsations and a decrease of the respiratory rhythm, while it continued to sleep, and gave no other visible sign of auditory stimulation. This chance observation led him to undertake a series of experiments on the primitive
