On October 16th George Lusk, the president of the Whitechapel Vigilance Committee, received a three-inch-square cardboard box in his mail. Inside was half a human kidney preserved in wine, along with the following letter. Medical reports carried out by Dr. Openshaw found the kidney to be very similar to the one removed from Catherine Eddowes, though his findings were inconclusive either way.
