Thornton notes that the phrase "Found drowned" was a stock formulation in newspaper headlines of the day. Gifford adds that "High water at Dublin bar" likewise comes directly from the popular press: it was the phrase used in the tidetables published in Thom's 1904 (p. 5 ff.).
Newspapers' use of the first phrase, Thornton observes, derived "from the fact that 'found drowned' is the official coroner's jury's verdict when a person is so found and no foul play is suspected. Such an instance occurs in the Freeman's Journal for March 29, 1904."
