   1856, Goold Brown, The First Lines of English Grammar, page 10

   [It] is desirable [...] that we may have a shorter and simpler term in stead of Double-u. [...] Dr. Webster [...] is not yet tired of his experiment with "oo;" but thinks still to make the vowel sound of this letter its name. Yet [...] If W is to be named as a vowel, it ought to name itself, as other vowels do, and not to take two Oes for its written name. Who that knows what it is, to name a letter, can think of naming w by double o?
