were obliged to admit the magical results of a really great man's superintendence. Then came a time when mere appreciation might well have grown to devout thankfulness at a providential conjunction of time, place, and man; for one morning Dr. Jones came to his new chief with a grave face to announce his discovery of a case which he could not but identify as that selfsame black fever whose germ Clarendon had found and classified. Dr. Clarendon showed no surprise but kept on at the writing before him. "I know," he said evenly; "I came across that case yesterday. I'm glad you recognized it. Put the man in a separate ward, though I don't believe this fever is contagious." Dr. Jones, with his own opinion of the malady's contagiousness, was glad of this deference to caution; and hastened to execute the order. Upon his return Clarendon rose to leave, declaring that he would himself take charge of the case alone. Disappointed in his wish to study the great man's methods and technique, the junior physician watched his chief stride away toward the lone ward where he had placed the patient, more critical of the new regime than at any time since admiration had displaced his first jealous pangs. Reaching the ward, Clarendon entered hastily, glancing at the bed and stepping back to see how far Dr. Jones's obvious curiosity might have led him. Then, finding the corridor still vacant, he shut the door and turned to examine the sufferer. The man was a convict of a peculiarly repulsive type, and seemed to be racked by the keenest throes of agony. His features were frightfully contracted, and his knees drawn sharply up in the mute desperation of the stricken. Clarendon studied him closely, raising his tightly shut eyelids, took his pulse and temperature, and finally dissolving a tablet in water, forced the solution between the sufferer's lips. Before long the height of the attack abated, as shown by the relaxing body and returning normality of expression, and the patient began to breathe more easily. Then, by a soft rubbing of the ears, the doctor caused the man to open his eyes. There was life in them, for they moved from side to side, though they lacked the fine fire which we are wont to deem the image of the soul. Clarendon smiled as he surveyed the peace his help had brought, feeling behind him the power of an all-capable science. He had long known of this case and had snatched the victim from death with the work of a moment. Another hour and this man would have gone--yet Jones had seen the symptoms for days before discovering them, and having discovered them, did not know what to do.Man's conquest of disease,
