Sir,-- In a clever article this morning you speak of ‘the doctrine of the enclitic De’--‘which, with all deference to Mr. Browning, in point of fact does not exist.’ No, not to Mr. Browning: but pray defer to Herr Buttmann, whose fifth list of ‘enclitics’ ends ‘with the inseparable De’--or to Curtius, whose fifth list ends also with ‘De (meaning ‘towards’ and as a demonstrative appendage)’. That this is not to be confounded with the accentuated ‘De, meaning BUT’, was the ‘doctrine’ which the Grammarian bequeathed to those capable of receiving it.-- I am, sir, yours obediently, R. B.”--‘Browning Soc. Papers’, Part I., p. 56.
