By 1890, it was reported by "Whittakers Almanack" to have 10,000 members, making it one of the largest clubs ever, but this level of membership proved to be short-lived; by 1890 its membership had halved to around the 5,500 level, and by 1900 it was still slightly further down, at 5,000.  It had closed by 1904, when its building was taken over by the pro-Tariff Reform United Empire Club.
