An old bachelor is generally very precise and exact in his habits. He has no one but himself to look after, nothing to distract his attention from his own affairs; and Mr. Dodgson was the most precise and exact of old bachelors. He made a précis of every letter he wrote or received from the 1st of January, 1861, to the 8th of the same month, 1898. These précis were all numbered and entered in reference-books, and by an ingenious system of cross-numbering he was able to trace a whole correspondence, which might extend through several volumes. The last number entered in his book is 98,721.

When I meet with any thing, that I think fit to put into my common-place-book, I first find a proper head. Suppose for example that the head be EPISTOLA, I look unto the index for the first letter and the following vowel which in this instance are E. i. if in the space marked E. i. there is any number that directs me to the page designed for words that begin with an E and whose first vowel after the initial letter is I, I must then write under the word Epistola in that page what I have to remark.
