The kidney removal of Catherine Eddowes.

[Herlock Sholmes]

No problem Herlock. It was just my apparently unsuccessful attempt at humour. When back pain robs me of sleep I become a little cranky. Plus, my wife informs me, I am a grumpy old b*****d to begin with.

I’m like that without any pain George.

I do get back pain but nowhere near as bad as you must do George but I live with a born pessimist’s concern that one day it might get worse. My brother suffers badly with Sciatica and even strong painkillers don’t fully wipe away the pain. I remember when I was a teenager my dad slipped a disk working in a foundry carrying a pot of molten aluminium with another man using a shank. He trod on something and went over; the other guy got a minor burn. He was was no lightweight when it came to pain but I saw him lying on his back on our living room floor in tears asking me to talk to him to try and take his mind of it. It’s one of the most vivid memories of my childhood.

I hope yours eases up George.

And the voice from the gloom saithe " Smile and be happy, for things could be much worse". So I smiled and was happy and lo, things became much worse.

[Coroner] Would it have been such an instrument as a medical man uses for post-mortem examinations? - The ordinary post-mortem case perhaps does not contain such a weapon.
[Coroner] Would any instrument that slaughterers employ have caused the injuries? - Yes; well ground down.

The Liston knife is not present in an "ordinary post-mortem case". I think that was the point he was making . I also think that he was suggesting that a slaughter's knife would have been possible only if it was ground down.

Cheers, George
