2o8 SYSTEMS OF TREATING STAMMERING movements; i.e. with the motor word-centre. As with the child, so with the adult. It is not at all necessary to suppose that sound finds any other path to the speech-organs than that opened to it by the physical well-being. With the adult, pleas- ure and mood stand in the same definite relation to interest in speech as they do with the child. When we feel contented and at ease, we start chattering at the least occasion. But if we feel depressed, even a real interest in a subject will elicit noth- ing but a few scanty monosyllables.1 . . . "An unbroken stream of words seems to depend simply and solely upon the existence of the corresponding thought and a sufficiently strong feeling of physical ease. When the well-being is great enough, we have only to think the train of thought, and the motor apparatus reproduces it automatically almost before we are fully aware of what has taken place."2 Our author then goes on to explain the manner in which fear and physical discomfort (Uribehagen) come to replace physical ease (Behagen) in the stammerer. This is the direct effect of the stam- merer's inability to speak. Dr. Sandow supposes that the speech-disturbances are due to injury to the speech-nerves and to impairment of the motor speech- centre of the brain. He supposes that these condi- tions are aggravated by the stammering, and that the stammering thus prevents reparation of the phy- sical injury. Concerning the remedy for these con- ditions, he says: 1 "Mechamk des Stottems," pp. 17-18. 2 Loc. cit., p. 19.
