Dr. Jekyll, a young physician, is possessed of the idea that medicine can affect the soul as well as the body, and has many discussions with his old friend Lanyon, a doctor of the old school. Jekyll continues to experiment in secret, and finally his efforts are crowned with success. He discovers a mixture that brings out all the bad in his nature, and another that will act as an antidote. Bat when he stands forth in his evil guise, Jekyll is horrified. He is such a wicked, repulsive creature that even the interests of science are lost sight of, and he decides to bury his discovery from everyone, realizing that it does not pay physicians or anyone else to bring out the evil that is in one. The doctor finds, however, that it is easy to start evil doing, but not always possible to accomplish reform. The wicked genius that he brought to the surface, simply in the interests of science, returns at intervals to plague him.
