The second division was a code book of 94 pages with 94 entries on each page. A code point was assigned for each number up to 94. Thus, only two symbols needed to be sent to transmit an entire sentence – the page and line numbers of the code book, compared to four symbols using the ten-symbol code. In 1799, three additional divisions were added.
