led by Prunella Bagot Stack.

More than six years ago this society was founded by Mrs. Bagot Stack to enable business girls and busy women to improve their physique. The first exercise class accompanied by music was attended by sixteen members in March, 1930. Since Mrs. Bagot Stack's death her sister, Mrs Cruickshank, and her daughter, Prunella, have carried on the good work. Over ninety classes are now held in London every evening; and 1,800 are held each week in the suburban, provincial, and Dominion centres.
