Etymology gleanings for January 2018: Part 1
My most recent post (mad as a hatter) aroused a good deal of criticism. The reason is clear: I did not mention the hypothesis favored in the OED (mercury poisoning). Of course, when I quoted the medical explanation of long ago, I should have written the last set of hypotheses… instead of the last hypothesis. I find all medical explanations of the idiom untenable, and I should have been explicit on this point, rather than hiding behind polite silence.
