Armistice give meaning to the curve.

2. Note the method of indicating the year, the month, and the day.

In this book, an illustration occupying a full page is referred to by page number. When there is more than one illustration on a page, each is identified by a letter of the alphabet. When there is more than one footnote beneath an illustration, each is numbered. Thus the cross reference 267B2 means page 267, illustration B, note 2.
