** “Double leads” is a technical phrase for a mode of printing which is employed only when an article is either supposed to be, or is wished to be supposed, super-import- ant. The lines stand wide apart, and look like the bars of a gridiron. _Mr. P._ Very well, Sir. There’s a long police case just come in, of a baronet’s daughter taken up for shoplifting; and an account of the bursting of a gasometer, which killed eleven men, three boys, and an old woman, who lived in a front garret over the way. _Editor_. Use them both, the shop-lifting under the head of “Mysterious Charge of Theft,” and the accident to the gasometer under that of “Tremendous Explosion!--Fifteen Lives Lost!” _Mr. P._ We shall do better with the _ads_. than I expected. Robins has just sent a long list of his auctions, which he says must go in to-morrow; and Kidd’s clerk has left eight or ten good book _ads._, so I shall be able to make out a full page without using the quacks. * * It is necessary to remark here, by way of explanation, that there are gradations of rank and respectability in advertisements; and that a high aristocratical feeling pervades their location in a well regulated paper. The _quack ads_., alluded to by Mr. Pica, are those benevolent offers of aid to the afflicted, which announce that “rheumatism and lumbago are effectually relieved by a new process;” that the most excruciating toothache is allayed in one minute by an unrivalled anodyne cement; that “gout is cured without medicine, in a few hours,” and “blotched faces in no time at all;” that red whiskers are changed in a single night to beautiful shades of brown or black;” that “the healthy functions of the stomach and intestinal canal, are restored by an improved domestic instrument,” &c. &c. These are never allowed to show their faces in the genteel company of the other advertisements, unless there happens to be a lack of gentility, but herd together in what is technically called the, “back page” of the paper.
