There are also certain minor details which deserve our attention, for there is nothing too minute for the student. It is best to write on wax owing to the facility which it offers for erasure, though weak sight may make it desirable to employ parchment by preference. The latter, however, although of assistance to the eye, delays the hand and interrupts the stream of thought owing to the frequency with which the pen has to be supplied with ink.

But whichever we employ, we must leave blank pages that we may be free to make additions when we will. For lack of space at times gives rise to a reluctance to make corrections, or, at any rate, is liable to cause confusion when new matter is inserted. The wax tablets should not be unduly wide; for I have known a young and over-zealous student write his compositions at undue length, because he measured them by the number of lines, a fault which persisted, in spite of frequent admonition, until his tablets were changed, when it disappeared.

Space must also be left for jotting down the thoughts which occur to the writer out of due order, that is to say, which refer to subjects other than those in hand. For sometimes the most admirable thoughts break in upon us which cannot be inserted in what we are writing, but which, on the other hand, it is unsafe to put by, since they are at times forgotten, and at times cling to the memory so persistently as to divert us from some other line of thought. They are, therefore, best kept in store.
