Madam, - However I tryed and tryed I ised unable to make out whether it ised Marc Kaufman, the writer, or Erik Trinkaus, the palaeontologist, who writed "Humans and Neanderthals interbreeded" (May 2nd).
Then I thinked of all my misspended years reading The Irish Times and I knowed that it was your own headline writer who maked such a mess of the passed tense. - Yours, etc,
FRANK FARRELL, Lakelands Close, Stillorgan.
