    This was pointed out by Mr. Savory in his Bradshaw lecture, 1886. It was shown that time was one of the principal attributes of movements. Hence the abnormal character of a nerve-muscular act is often a relation as to time : the rapidity of talk, the slowness of response to questions or to impressions, may show mental abnormality. In chorea the time of move- ments is very different from the normal. The study of pathological histology has added greatly to our knowledge; still we have much need of information as to the causes or antecedents of such conditions of growth. It appears, then, to be important whenever we study a pathological growth, to look to the action of those forces which stimu- late and control its nutrition. We have now to consider the action of those forces which precede healthy or unhealthy growth respectively in parts of the subject. Defective stimulation, or the continued non- stimulation, of a certain series of movements in man, tends to loss of that special motor-action, or special mode of co-ordination of nerve-centres. It may be lost from want of use in the individual, and in the course of generations it- may be lost in the species.. On the contrary, frequent stimulation
