This class of riddle is of recent introduction. The Arithmorem is made
by substituting figures in a part of the word indicated, for Roman
numerals. The nature of the riddle--from the Greek _arithmos_, number,
and the Latin _remanere_, back again--will be easily seen from the
following example, which is a double Arithmorem:
H 51 and _a tub_--a fine large fish.
A 100 and _gore_--a sprightly movement in music.
R 5 and _be_--a part of speech.
U 551 and _as and_--a Spanish province.
To 201 and _ran_--a stupefying drug.
R 102 and _nt_--an acid.
OU 250 and _pap_--a Mexican town.
The answer is Havanna--Tobacco.
