A new Method of a Common-Place-Book.

Adversariorum Methodus.] As to the language, in V. which one ought to express the heads, I esteem 8. the Latin tongue most commodious, provided the nominative case be always kept to, for fear lest in words of two syllables, or in monosyllables that begin with the vowel, the change, which happens in oblique cases, should occasion confusion. But it is not of much consequence what language is made use of, provided there be no mixture in the heads of different languages.

To take notice of a place in an author, from whom I quote something, I make use of this method: before I write any thing, I put the name of the author in my common-place-book, and under that name the title of the treatise, the size of the volume, the time and place of its edition, and (what ought never to be omitted) the number of pages that the whole book contains. For example, I put into the class M a, "Marshami Canon Chronicus Ægyptiacus, Græcus, et disquisitiones fol." London, 1672, p. 626. This number of pages serves me for the future to mark the particular treatise of this author, and the edition I make use of. I have no need to mark the place, otherwise than in setting down the number of the page from whence I have drawn what I have wrote, just above the number of pages contained in the whole volume. You will see an example in Acherusia, where the number 259 is just above the number 626, that is to say, the number of the page, where I take my matter, is just above the number of pages of the whole volume. By this means I not only save myself the trouble of writing Canon Chronicus Ægyptiacus, &c. but am able by the rule of three to find out the same passage in any other edition, by looking for the number of its pages; since the edition I have used, which contains 626, gives me 259.
