During the whole of this summer Grimaldi's health gradually but steadily declined. Sometimes there were slight fluctuations for the better, in which he felt so much improved as to fancy that his strength was beginning to return; and although the next day's decay and lassitude showed but too clearly that they were but brief intervals of strength, he fondly regarded these red-letter days as tokens of a real and permanent change for the better. Perhaps even now, as he had nothing to do at Sadler's Wells, and was too unwell to accept country engagements, if he had remained quiet during the Covent Garden recess, lived with great regularity, and acted upon the best medical advice, he might have retained for many years longer some portion of his health and spirits. But Mr. Glossop, who was then the lessee of the Coburg Theatre (now the Victoria), made him an offer which he could not resist, and he acted there for six weeks,[80] at a considerable sum per week and a free benefit. The engagement turned out so profitable a one for the management, that he might have renewed it for the same space of time, if he had not become too ill to appear upon the stage. At this crisis of his disorder Grimaldi was advised to try the Cheltenham waters. He went to Cheltenham in August, and being somewhat recovered by the change of air, consented to act for Farley and Abbott, who had taken the theatre on speculation, for twelve nights. He cleared 150_l._; and whether this sum of money, or the waters, or the change of scene revived him is uncertain, but he felt greatly improved in health when he returned to London for the opening of Covent Garden, to commence what ultimately proved to be his last season at that theatre.
