In August, 1780, Horace Walpole visited "The Temple of Health" in the Adelphi, and pronounced it "the most impudent puppet-show of imposition I ever saw, and the mountebank himself the dullest of his profession, except that he makes spectators pay a crown apiece for admission only." The place acquired notoriety so rapidly that, on September 2, George Colman, the elder, produced at the Haymarket Theatre a skit entitled _The Genius of Nonsense_, in which John Bannister, in the character of the Emperor of Quacks, mimicked Graham. "His satin sofas on glass legs, his celestial bed, his two porters in long, tawdry greatcoats and immense gold-laced cocked hats, distributing handbills at the door, while his goddess of health was dying of a sore throat from squalling songs at the top of the staircase, were all hit off by a speaking harlequin, who also caricatured the doctor's sliding walk and bobbing bows."[41] The impostor was prevented from buying the "bill of the play," a burlesque on his own handbill, so that he could not bring an action for libel. The following is an exact copy of one of Graham's advertisements:-- TEMPLE OF HEALTH, Adelphi. To their Excellencies the Foreign Ambassadors, To the Nobility, Gentry and to Persons of Learning and Taste, This Evening exactly at Eight o'Clock, The Celestial Brilliancy of the Medico-electrical Apparatus, in all the Apartments of the TEMPLE, Will be exhibited by Dr Graham himself, Who will have the honour of explaining the true Nature and effects of Electricity, Air, Music, and Magnetism, when applied to the human body. In the introductory Oration, the whole art of enjoying health and vigour, of body and of mind, and of preserving and exalting personal Beauty and Loveliness; or, in other words, of living with health, honour, and happiness in this world, for at least a hundred years, is pointed out and warmly inculcated. Previous to the display of the electrical Fire, the Doctor will delicately touch upon the Celestial Beds, which are soon to be opened in the Temple of Hymen, in Pall-mall, for the propagation of Beings rational, and far stronger and more beautiful in mental as well as in bodily endowments--than the present puny, feeble, and nonsensical race of probationary immortals, which crawl and fret, and politely play at cutting one another's throats for nothing at all, on most parts of this terraqueous globe. This apparatus, which visibly displays, as it were, the various faculties of the material soul of universal and eternal Nature, is acknowledged by all who have seen it, to be by far the largest, most useful, and most magnificent that now is, or that ever was, in the world; and it may be inspected every day, from Ten o'clock in the Morning till four in the Afternoon. Admittance at night, 5s.; in the day, 2s. 6d.
