The "From Hell" letter was received by George Lusk, leader of the Whitechapel Vigilance Committee, on 16 October 1888. The handwriting and style is unlike that of the "Dear Boss" letter and postcard. The letter came with a small box in which Lusk discovered half of a kidney, preserved in "spirits of wine" (ethanol). Eddowes' left kidney had been removed by the killer. The writer claimed that he "fried and ate" the missing kidney half. There is disagreement over the kidney: some contend it belonged to Eddowes, while others argue it was nothing more than a macabre practical joke. The kidney was examined by Dr Thomas Openshaw of the London Hospital, who determined that it was human and from the left side, but (contrary to false newspaper reports) he could not determine its gender or age. Openshaw subsequently also received a letter signed "Jack the Ripper".
