From MICHAEL WELLS
Perhaps Anthony Edwards should have waited a little longer for the morning
mists to clear from around his bathtub (Forum, 7 December), for he has erred
by a factor of 1000 on two occasions in his opening paragraph. Four hundred
megalitres of shampoo would be 88 million gallons, rather than ‘nearly 100
000′, and the conversion factor relating M and m is a billion (109) not
a million. I feel that Edwards is perhaps confusing his M’s with his K’s
– those morning mists again, maybe.
