In a paper on the application of thought to textual criticism which I read before the Classical Association at Cambridge in 1921 (Proceedings vol. XVIII pp. 67–84)I made some remarks which I abbreviate as follows: ‘One of the forms assumed by thoughtlessness in textual criticism is the endeavour, now frequent especially among Continental scholars, to break down accepted rules of grammar or metre by the mere enumeration of exceptions found in MSS. That can never break down a rule: number is nothing; what matters is weight, and weight can onlybe ascertained by scrutiny. If I had noted every example I have met, I should now have a large collection of passages where orbis, which our grammars and dictionaries declare tobe masculine, has a feminine adjective attached to it. But I do not therefore propose to revisethat rule of syntax; for scrutiny would show that these examples, though numerous, have no force. In most of them the context proves that orbem, orbis, orbes, etc., are merely corruptions of the corresponding case and number of urbs; and in the rest it is natural to suppose that the scribe has been influenced and confused by the likeness of the one word to the other.’
