Hunger \Hun"ger\, n. [AS. hungor; akin to OFries. hunger, D.

      food; a craving or desire for food.

   Note: The sensation of hunger is usually referred to the
         stomach, but is probably dependent on excitation of the
         sensory nerves, both of the stomach and intestines, and
         perhaps also on indirect impressions from other organs,
         more or less exhausted from lack of nutriment.
         [1913 Webster]

   2. Any strong eager desire.

Bouvier's Law Dictionary, Revised 6th Ed (1856):

HUNGER. The desire for taking food. Hunger is no excuse for larceny. 1 Hale,
P. C. 54; 4 Bl. Com. 31. But it is a matter which applies itself strongly to
the consciences of the judges in mitigation of the punishment.
     2. When a person has died, and it is suspected he has been starved to
death, an examination of his body ought to be made, to ascertain whether or
not he died of hunger. The signs which usually attend death from hunger are
the following: The body is much emaciated, and a foetid, acrid odor exhales
from it, although death may have been very recent. The eyes are red and
open, which is not usual in other causes of death. The tongue and throat are
dry, even to aridity, and the stomach and intestines are contracted and
empty. The gall bladder is pressed with bile, and this fluid is found
scattered over the stomach and intestines, so as to tinge them very
extensively. The lungs are withered, but all the other organs are generally
in a healthy state. The blood vessels are usually empty. Foder‚, tom. ii. p.
276, tom. iii. p. 231; 2 Beck's Med. Jur. 52; see Eunom. Dial. 2, Sec. 47,
