It was an exquisite deep blue just then with filmy white clouds drawn up over it like gauze.

“The Beth Book” (1897) by Sarah Grand (a pseudonym of Frances Elizabeth Clarke McFall) includes the above 76 letter sentence which contains the whole alphabet in the 65 letters from the x of exquisite to the z of gauze. This nugget of wisdom appears in the chapter on pangrams in “The Oxford Guide to Word Games” by Tony Augarde (Oxford University Press, 1984).
Augarde does not reveal who discovered this accidental gem but it may very well have been C.C. Bombaugh in his “Facts and Fancies from the Harvest Fields of Literature” of 1905.
In “Language on Vacation” (1965) Dimitri Borgmann found five words which together comprise the whole alphabet— phlegms, fyrd, wuz, qvint, and jackbox —but could not make a sensible sentence out of them. It’s hardly surprising. The shorter the pangram, the less sense it makes.
