19th Century Surgical Instruments: Wellcome Collection
Dr Lyttleton Forbes Winslow continued his considerations on the identity of Jack the Ripper in his ‘Recollections’ (1910):
After the fifth and sixth murders, however, I changed my views. The exact similarity in the method of murder and the horrible evisceration of the body showed too much of a methodical nature ever to belong to a man who committed the deeds in a fit of epileptic furor.
Considerable anatomical knowledge was displayed by the murderer, which would seem to indicate that his occupation was that of a butcher or a surgeon.
