Dearest Ada, 1st March.
We must meet at uncle's by 6 o'clock precisely. I intend taking you to the Haymarket Theatre to see William Shakspere's play of "Hamlet."
With kind love,
I am, ever yours,
Thomas.
CHRONOGRAMS.
A chronogram is a sentence or inscription in which occur words, containing, as initial letters or otherwise, letters that represent the Roman numerals. In some chronograms the initial letters only are counted as forming the solution of the puzzle, but in others all the letters contained which may be used as Roman numerals are taken into account. History supplies us with many first-rate chronograms; in fact, it was once the custom to strike medals with chronogrammatic sentences, in which the date of the occasion commemorated was set forth by the initial letters of the superscription.
Queen Elizabeth died in the year 1603, and the following chronogram relating to that event has come down to us:—
"My Day Is Closed In Immortality."
