On the evening of December 10, 1886, as Cobb was coming out of the Cosmos, a favorite club of the young gentlemen of San Francisco, he had run into an old and crippled man who was passing down the street. Cobb was in a hurry as he emerged from the place, and did not notice the poor pedestrian in time to avoid a collision. The consequences were that the old man was knocked to the ground, and appeared to be badly hurt. Cobb at once stopped and lifted the man up to ascertain the extent of his injuries, and finding him still insensible, had called a hack to convey him to the nearest druggist. The man was about sixty years of age, his right leg partially paralyzed, the sight of his right eye gone, and deep scars upon his face and neck. His clothes were shabby and much worn, yet there were indications that the man had seen better days. That portion of his face which was not scarred and seamed, gave evidence of quickness and perception, and a general appearance of knowledge and former refinement was plainly noticeable. His hands, too, were not those of a man accustomed to hard work. This man was Jean Colchis, a native of France, but a refugee from that country. He had, in his time, been a great chemist; he had been noted, far and near, as a man greatly gifted in the sciences, and one who had given much to his native country in the way of scientific invention; but, at a later day in his life, he had been led away by the persuasion of others to engage in a plot against the ruling power of his land. This plot being discovered, he was sentenced to death, but, escaping, had taken refuge in the United States. He was the recipient of a small pension from the members of his family who had not joined in the conspiracy, and upon this small pension Jean Colchis lived in the humble and rickety house in Duke's Lane. The pension was sufficient for all the needs of the old man and his only daughter, a lovely girl of seventeen years; it gave them their daily sustenance and life, and a slight margin from which to purchase the few things he needed to continue the one hobby of his life, chemical analysis. When Cobb had taken the old man to the druggist's, an examination had shown that nothing but a slight contusion of the side of the head had resulted from the unexpected knock-down he had received. He soon regained his senses, but was in a weak and helpless condition. Learning from him the place of his abode, Cobb at once took him there in a hack, and carefully attended him during the remainder of that evening. Such was the introduction of Junius Cobb to Jean Colchis. Cobb's kindness to the old Frenchman was rewarded by an invitation to call again, and as he descended the stairs of the old, rain-beaten house, he resolved to come the next evening.
