For the company to assemble at a late hour and engage in unusual, exciting and severe exercise throughout the entire night, is often too great a tax upon the physical system. To dress too thinly, and in a state of perspiration to be exposed, as ladies at the ball frequently are, to draughts of cold, is oftentimes to plant the seeds of a disease from which they never recover. Again, to come in contact, as ladies are liable to, more especially at the public ball, with disreputable men, is sometimes to form alliances that will make a lifetime of sorrow.' —Thomas E. Hill, Evils of the Ball, 1883
