From Angus Mair
Your article about hibernation (21 January, p 28) reminded me of the procedure that veterinary surgeon and author James Herriott (real name Alf Wight) describes accidentally performing in the 1930s. Deciding that a dog is best put down, he administers a large dose of anaesthetic. The dog falls into a deep sleep but, instead of waking up dead, makes a somnolent but complete recovery to the bafflement of all concerned.
