A new chapter is identified at once by a larger allowance of blank at the top of that page. A change of importance in the subject-matter of the text, like that of a document, extract, or letter, is more plainly indicated by putting a full blank line before and after the insert. A change of minor importance is indicated by putting a small square of white, known as the em quadrat, at the beginning of a new paragraph. This petty square of white makes a break in the regular outline of the page which arrests attention almost as plainly and more neatly than was done by the ¶ or ⸿ which were the paragraph-marks of the early printers.
