Not illustrated. 1904 Excerpt: ...of each hand was again taken, and the reaction time of the two index and the left middle fingers were again taken. The results indicated an oscillation in fatigue throughout the various sets of experiments. The pressure of the left hand steadily diminished; but at the end of four or five series that of the right hand was often augmented. At the end of the experiment the reaction time of the two index fingers was found to be less than at the beginning; but that of the middle finger was increased.

Musk and ethereal odors, the taste of sugar, acetic acid and sulphate of quinine all reinforced the working finger. Alcohol and bouillon merely taken into the mouth increased the amount of work that could be done more than when swallowed. Tastes were found, as a rule, to reinforce the working finger more than odors, and both together operated more powerfully than either separately. Cutaneous sensations, such as heat, cold, and rubbing, had also a tonic effect. In another article in the same volume of this magazine, M. Fere came to these conclusions: "Le travail mecanique de la main gauche est moins influence" par le travail intellectuel que le travail mecanique de la main droite. Le travail de la main gauche gagne moins quand il coincide avec un travail intellectuel facile, il perde moins quand il coincide avec un travail intellectuel relativement complique." M. Fere has made a number of other studies in the reinforcement of voluntary muscular contractions; but it will not ...
