The latter showed an increase in the strength of thepains when quinine was administered orally. The length of the con-tractions was decreased in both instances after the hypodermic useof quinine, while the rapidity was increased in one and unchangedin another. When quinine was given orally there was an increase in the strengthof contractions four times, once quite marked, and once there wasa decrease in the strength of contractions. The duration of the painswas increased once, unchanged once and decreased three times.
