_Name of Infants._--In Scotland there is a superstition that it is unlucky to tell the name of infants before they are christened. Can this be explained? R. J. A. _Geometrical Curiosity._--Take half a sheet of note-paper; fold and crease it so that two opposite corners exactly meet; then fold and crease it so that the remaining two opposite corners exactly meet. Armed with a fine pair of scissors, proceed now to repeat both these folds alternately without cessation, taking care to cut off quite flush and clear all the overlappings on both sides after each fold. When these overlappings become too small to be cut off, _the paper is in the shape of a circle_, _i. e._ the ultimate intersection of an infinite series of tangents. Perhaps PROFESSOR DE MORGAN will give the _rationale_ of this procedure. C. MANSFIELD INGLEBY. Birmingham. _Denison Family._--Can any correspondent of "N. & Q." inform me how the Denisons of Denbies, near Dorking, in Surrey, and the Denisons of Ossington, in Nottinghamshire, were related? Who was Mr. Robert Denison of Nottingham, who took a very active part in politics at the commencement of the French Revolution? His wife had a handsome legacy from a rich old lady, one Mrs. Williams, of whom I would much like to know something farther. E. H. A. _"Came."_--In Pegge's _Anecdotes of the English Language_, p. 189., we read: "The real preterit of the Saxon verb _coman_, is _com_. _Came_ is therefore a violent infringement, though it is impossible to detect the innovator, or any of his accomplices." When was the word _came_ introduced into our language? Early instances of its use would be very welcome. H. T. G. Hull. _Montmartre._--By some this name is derived from _mons martis_; by others from _mons martyrum_. Which is the more satisfactory etymology, and upon what authority does it rest? HENRY H. BREEN. St. Lucia. _Law of Copyright: British Museum._--Observing that the _new_ law of copyright, which was passed and came into operation on the 1st of July, 1842, _expressly repeals_ all of the statutes previously existing on that subject, I am anxious to know, through the medium of "N. & Q.," if the British Museum authorities can claim and enforce the delivery of any book, _although not entered on the books of Stationers' Hall_, which may have been printed and published _before_ the passing of the said act of 1842. If so, then what is the state of the act or statute which bears upon that particular privilege? J. A. Glasgow.
