His humor was so entirely fresh and unconventional, that it took his hearers by surprise, and charmed them.  His failing health compelled him to abandon the lecture after about eight or ten weeks.  Indeed, during that brief period he was once or twice compelled to dismiss his audience.  Frequently he sank into a chair and nearly fainted from the exertion of dressing.  He exhibited the greatest anxiety to be at his post at the appointed time, and scrupulously exerted himself to the utmost to entertain his auditors.  It was not because he was sick that the public was to be disappointed, or that their enjoyment was to be diminished.  During the last few weeks of his lecture-giving, he steadily abstained from accepting any of the numerous invitations he received.  Had he lived through the following London fashionable season, there is little doubt that the room at the Egyptian Hall would have been thronged nightly.  The English aristocracy have a fine, delicate sense of humor, and the success, artistic and pecuniary, of "Artemus Ward" would have rivalled that of the famous "Lord Dundreary."  There were many stupid people who did not understand the "fun" of Artemus Ward's books.  There were many stupid people who did not understand the fun of Artemus Ward's lecture on the Mormons.  Highly respectable people--the pride of their parish--when they heard of a lecture "upon the Mormons," expected to see a solemn person, full of old saws and new statistics, who would denounce the sin of polygamy,--and rave without limit against Mormons.  These uncomfortable Christians do not like humor.  They dread it as a certain personage is said to dread holy water, and for the same reason that thieves fear policemen--it finds them out.  When these good idiots heard Artemus offer if they did not like the lecture in Piccadilly, to give them free tickets for the same lecture in California, when he next visited that country, they turned to each other indignantly, and said, "What use are tickets for California to us? WE are not going to California.  No! we are too good, too respectable to go so far from home.  The man is a fool!"  One of these vestrymen complained to the doorkeeper, and denounced the lecturer as an impostor--"and," said the wealthy parishioner, "as for the panorama, it is the worst painted thing I ever saw." During the lecture Artemus was always as solemn as the grave.  Sometimes he would seem to forget his audience, and stand for several seconds gazing intently at his panorama.  Then he would start up and remark apologetically, "I am very fond of looking at my pictures."  His dress was always the same--evening toilet.  His manners were polished, and his voice gentle and hesitating.  Many who had read of the man who spelled joke with a "g," looked for a smart old man with a shrewd cock eye, dressed in vulgar velvet and gold, and they were hardly prepared to see the accomplished gentleman with slim physique and delicate white hands.
