that the Scottish clergy of that age would never have suffered any Buckle the Beggars to rank with them as regular preachers, though "out of employment."

Devil, Proper Name.

—Will any of your correspondents kindly inform me whether there are any persons now existing of the name of Devil; or who bear the devil on their coat of arms? In 1847 I saw upon the panel of a carriage in London the devil's head for a crest. To what family does this belong? "Robin the Devil" is mentioned in Rokeby, cant. vi. st. 32. The following is from the Monthly Mirror, August, 1799:

"Formerly there were many persons surnamed 'the Devil.' In an ancient book we read of one Rogerius Diabolus, Lord of Montresor." "An English monk, Willelmus, cognomento Diabolus. Again, Hughes le Diable, Lord of Lusignan. Robert, Duke of Normandy, son of William the Conqueror, was surnamed 'the Devil.' In Norway and Sweden there were two families of the name of 'Trolle,' in English, 'Devil;' and every branch of these families had an emblem of the devil for their coat of arms. In Utrecht there was a family called 'Teufel' (or Devil); and in Brittany there was a family of the name of 'Diable.'"

Can a Clergyman marry himself?

—If a clergyman were to perform the marriage service in his own case, would it be valid? Has such an occurrence ever been known?

Ground Ice.

—Has any satisfactory explanation been given of the mode in which the peculiar substance termed ground ice is formed in certain rivers. I am most familiar with it as seen in the Wiltshire Avon. It is seen in some rivers in Lincolnshire, where I am told it is called ground-gru. One who has noticed it in the Teviot says, that the inhabitants there call it "sludge."

The fact of ice being formed at the bottom of streams, where we should expect a higher temperature, is so curious an anomaly, that it would be desirable to collect instances where and at what depths it is observed.

Astrologer-Royal.

—I remember, in a former volume of "N. & Q.," some mention is made of Almanacks, Astrologers, &c. It escaped me at the time to tell you that the ancient office of King's Astrologer happens not to have been subjected to formal abolition, and, being hereditary, it is now vested in the person of Mr. Gadbury, resident at Bristol. He is auctioneer to the Court of Bankruptcy, and a very worthy man. He tells me there is neither salary nor privilege attached to his nominal post.

William, second Duke of Hamilton.

—Can any of your numerous correspondents inform me if there is any monumental inscription, or other memorial, dedicated to the memory of William, second Duke of Hamilton, who expired on the 12th of September, 1651, from the effects of a wound received at the battle of Worcester on the 3rd of the same month? He was interred before the high altar in Worcester Cathedral, having died at the Commandery in that city; but there is neither
