Pangram

The only perfect pangrams of the English alphabet that are known use abbreviations or other non-dictionary words, such as "Blowzy night-frumps vex'd Jack Q."

"[3] or they include words so obscure that the phrase is challenging to understand, such as "Cwm fjord-bank glyphs vext quiz",[3] in which cwm is a loan word from the Welsh language meaning an amphitheatre-like glaciated depression, vext is an uncommon way to spell vexed, and quiz is used in an archaic sense to mean a puzzling or eccentric person.

It means that symbols in the bowl-like depression on the edge of a long steep sea inlet confused an eccentric person.

("Mr.Sangkhaphant Hengpithakfang - an elderly man who earns a living by selling bottles - was arrested for prosecution by police because he stole Lady Chatchada Chansamat's watch.")

In the sequel, Sallows built an electronic "pangram machine", that performed a systematic search among millions of candidate solutions.

[17] The search successfully comes to an end when the phrase "Pack my box with five dozen liquor jugs" is discovered (which has only 6 duplicated vowels).

The scientific paper Cneoridium dumosum (Nuttall) Hooker F. Collected March 26, 1960, at an Elevation of about 1450 Meters on Cerro Quemazón, 15 Miles South of Bahía de Los Angeles, Baja California, México, Apparently for a Southeastward Range Extension of Some 140 Miles has a pangrammatic title, seemingly by pure chance.
