'The Fatal Thirteen -Death from excessive dancing
Dr Waldo held an inquest at the Southwark Coroner's Court on Wednesday on the body of Mary Ann Cocklin, aged 35 years, the wife of a Bermondsey labourer.
John Cocklin, the husband, stated that he and the deceased went to a Christmas party at the house of a relative on Christmas Day, and kept on dancing until after midnight. Deceased then lay down to rest, but awoke in a fright, screaming that three men were after her.
Dr Waldo: Had she been drinking any spirits?
Witness: No, sir, only port wine. We had nothing but port wine, any of us.
Dr Waldo: What happened when she came to herself again?
Witness: She went down stairs and resumed dancing to the music of an automated piano organ we had in the house. I next heard she was very ill, and that she had again gone to rest, but had turned giddy and fallen down the stairs.
Dr Waldo: How many?
Witness: The fatal 13.
Susan Poore, a neighbour, stated that she heard the deceased fall. She was taken to Guys Hospital, where she died the same day.
The medical evidence showed that death was due to fracture of the thigh caused by the fall, which was the result of giddiness produced by dancing. A verdict was returned accordingly'.
