Concert Hall was crowded as soon as The Fejee Mermaid moved in. Levi Lyman, as Dr. Griffin, told the audiences of his travels and adventures in far-off places in search of unnatural curiosities. Barnum was afraid that some of those who visited Concert Hall might recognize Dr. Griffin as the Levi Lyman who had accompanied Joice Heth, but Joice Heth had been dead six years, and no one doubted Dr. Griffin; he looked scientific. He was dignified and polite, and he explained with great pains and patience the science and natural history of the connecting links by which he was surrounded. After one week at Concert Hall, Barnum announced that at last, after much trouble and expense, he had induced Dr. Griffin to exhibit The Fejee Mermaid at Barnum’s American Museum, where it could be seen daily, along with the other curiosities, without extra charge. Barnum designed an enormous flag, representing a mermaid eighteen feet long, which, when it was unfurled, covered the front of the Museum. This was too much, even for Lyman, who protested against such a colossal deception: The Fejee Mermaid was only three feet long. Lyman indignantly told Barnum that the public would not swallow such a difference between its expectations and the reality, and he insisted that the flag be taken down. Barnum answered that he had paid seventy dollars for that flag, and it must remain in front of the Museum. “Well, Mr. Barnum,” Lyman answered, “if you like to fight under that flag, you can do so, but _I_ won’t.” Barnum could not dispense with Professor Griffin, and the flag was hauled in. It is strange that Lyman should choose this flag as an issue, and Barnum does not explain it, but it was likely that Lyman was having considerable difficulty satisfying many disappointed visitors with his wizened mermaid, and could endure no further difficulties. Lyman later went to Nauvoo, Illinois, where he became an influential Mormon.
