~Circuses.~--The first notice we have of any circus visiting Birmingham is that of Astley's which came here October 7, 1787. In 1815 Messrs. Adams gave performances in a "new equestrian circus on the Moat," and it has interest in the fact that this was the first appearance locally of Mr. Ryan, a young Irishman, then described as "indisputably the first tight-rope dancer in the world of his age." Mr. Ryan, a few years later, started a circus on his own account, and after a few years of tent performances, which put money in his pocket, ventured on the speculation of building a permanent structure in Bradford-street, opening his "New Grand Arena" there in 1827. Unfortunately, this proved a failure, and poor Ryan went to the wall. The circus (known now as the Circus Chapel), long lay empty, but was again re-opened May 19, 1838, as an amphitheatre, but not successfully. In 1839 the celebrated Van Amburgh, whose establishment combined the attractions of a circus and a menagerie, visited this town, and his performances were held, rather strangely, at the Theatre Royal. On the night of the Bull Ring Riots, July 15th, when there was "a full house," the startling news that a number of buildings were on fire, &c., was shouted out just at the moment that Van Amburgh was on the stage with a number of his well-trained animals. He himself was reclining on the boards, his head resting on the sides of a tawny lion, while in his arms was a beautiful child, four or five years old, playing with the ears of the animal. The intelligence naturally caused great excitement, but the performer went quietly on, hoisting the little darling to his shoulder, and putting his animals through their tricks as calmly as if nothing whatever was the matter. In 1842, Ducrow's famous troupe came, and once again opened Ryan's Circus in the Easter week, and that was the last time the building was used for the purpose it was originally erected for. Cooke's, Hengler's, Newsome's, and Sanger's periodical visits are matters of modern date. The new building erected by Mr. W.R. Inshaw, at foot of Snow Hill, for the purposes of a Concert Hall, will be adaptable as a Circus. ~Climate.~--From the central position in which Birmingham is situated, and its comparative elevation, the town has always been characterised as one of the healthiest in the kingdom. Dr. Priestley said the air breathed here was as pure as any he had analysed. Were he alive now and in the habit of visiting the neighbourhood of some of our rolling mills, &c., it is possible he might return a different verdict, but nevertheless the fact remains that the rates of mortality still contrast most favourably as against other large manufacturing towns.
