—Will you allow me on this subject to put to men of science, and to watchmakers, the à priori question—Is the alleged fact mechanically possible?

AVENA.

A regular Mull—Origin of the Phrase.

—"You have made a regular mull of it," meaning a complete failure. This expression I have often heard, from my school days even to the present time. Can you give me the origin of it? In reading a very clever and interesting paper communicated by J. M. Kemble, Esq., to the Archæological Institute of Great Britain and Ireland in the volume of their proceedings for 1845, entitled, "The Names, Surnames, and Nicnames of the Anglo-Saxons," I found the following paragraph:

"Two among the early kings of Wessex are worthy of peculiar attention, viz., the celebrated sons of Cênberht, Cædwealha and his brother Mûl. Of the former it is known, that after a short and brilliant career of victory, he voluntarily relinquished the power he had won, became a convert to Christianity, and having retired to Rome, was there baptised by the name Petrus, and died while yet in the Albs, a few days after the ceremony. His brother Mûl, during their wars in Kent, suffered himself to be surprised by the country-people and was burnt to death, together with twelve comrades, in a house where they had taken refuge."

This "Note," I think, answers my Query. Do you know of any other explanation?

Register-book of the Parish of Petworth.

—Can any reader of "NOTES AND QUERIES" assist in discovering a document which was formerly quoted by this title? Heylin used it for the reign of Edward VI., but his learned editor (Mr. Robertson) appears to have searched for it in vain.
