AMBERG, am'borK. The old capital of the Tapper Palatinate in Bavaria, 35 miles east of Nuremberg and 32 north of Ratisbon (Map: Bavaria, D 4 ) . It is situated on both sides of the Vils, and is well built. The ancient walls are noAV transformed into shady avenues. Amberg
is the seat of the court of appeal for the district,
possesses a library of 34,000 volumes, a lyceura,
an agricultural and industrial school, a munici-
pal hospital, a house of correction, etc. There
is also a royal factory for the manufacture of
arms. The Jirincipal products are earthenware,
woolen cloths, ironmongery, and beer. Near Am-
berg, Archduke Charles defeated the French un-
der .lonrdau on August 24, 1796. Pop., 1890,

AMBERGER, -iraljerK-er, Ciiristoph (c. 1500-
c. 1501?). A German painter. He was received
into the Augsburg guild in 1530, and is best
known for his careful portraits of contempora-
ries, particularly those of Charles V., Frunds-
berg, and the geographer iliinster. Various
altar-pieces by hiui are in Augsburg churches.
AMBERGRIS, amTier-gi-es (Fr. ainlre gris, gray amber; Ar. 'anbar) . Also spelled amherghse and (tmhergrcase. A fatty secretion formed in the bowels of some sperm whales (q.v.), and valued as a material for perfume. It is taken from whales directly, but more is found floating in waters (especially of the tropics) frequented by these cetaceans, or cast upon the beaches in lumps of all sizes up to a mass exceeding 200 pounds in weight. It is lighter than water, gray marbled with blackish in color, opaque and waxy in consistency, softens readily under heat, melting into resinous liquid at 145° F., and develops on exposure to the air a sweet,
"earthy" odor in place of its disagreeable smell when first taken from a whale. Chemically, it is soluble in oils, but resists acids; and it dissolves readily in hot alcohol, yielding a substance termed ambrein. As this is closely related chemically to known biliary secretions, it is further evidence that ambergris is of this nature, perhaps induced by, and partaking of, the squids upon
which the" sperm whale largely feeds, remains of whose beaks are frequently found mixed with it. Like other bezoars and substances of mysterious origin, ambergris was formerly regarded as an efHcacious medicine, but its virtues were imaginary, and it is no longer used in pharmacy, nor as a flavor in cookery, except among a few
barbarians of the East. It has a high commercial value, however, as a material for the manufacture of various perfumes, and the price is increasing, owing to the increasing rarity of the &perni whale, and a growing demand. Hence it is adulterated and imitated; a test of its genuineness is described as "its solubility in hot alcohol, its fragiant odor, and its uniform fatty con-
sistence on being penetrated by a hot wire."
AM'BER ISLANDS, or Electrides. In later Greek gei>j;rai)hy. the islands, famed for their amber, in the North Sea, from Denmark to the mouth of the Rhine. Also certain islands at the mouth of the legendary river Eridanus (the Po).

AM'BIGU'ITY (Lat. iimhigiius, going about
hither and thither, uncertain, doubtful). In law,
the duplicity or uncertainty of meaning of a
word, clause, or other part of a written instru-
ment. The rule of evidence forbidding the ad-
mission of parol evidence to contradict, vary, or
explain a written document is subject to the
important exception that parol evidence may
be introduced for the purpose of explaining an
ambiguit.v in a written instrument. Ambiguities
are "patent" and "latent." A patent ambigu-
ity is one which appears on the face of an in-
strument without referring to any intrinsic fact
or circumstance. Thiis, if a testator after refer-
ring in liis will to two persons named John, made
a bequest to John, the term of the bequest would
constitute a patent ambiguity. A latent ambigu-
ity is one which is disclosed only by the proof of
extrinsic facts. TIius, if a testator made a be-
(juest to a person, naming or otherwise describ-
ing him, and it appeared extrinsically that there
were two persons answering the description, the
terms of the bequest would constitute a latent
ambiguity. It is sometimes said that parol evi-
dence cannot be introduced to explain a latent
ambiguity. While the judicial decisions are not
altogether harmonious, the weight of authority
does not favor such a rule. See the authorities
named under the titles Contract, ill, and
Evidence.
