the name of Vesalius, though using his figures and
descriptions. Thomas Vicary, in 1548, is said to be
the first who wrote in English on A. ;+he published
The Anglishman’s Treasure, or the True A. of Man’s
Body. John Ligeus, in 1555, published an anatomi-
cal treatise in Latin hexameters. Franco (1556),
Valverda, Columbus, and others, wrote works of great
merit on A. In 1561, Gabriel Fallopius professed
it with great distinction at Padua, and made many
original discoveries.
In the 17th c., progress was rapid: Hervey, in
1619, discovered the circulation of the blood, and
the microscope was employed to detect the structure
of minute vessels. Aselli, in 1622, discovered and
demonstrated the existence of the lymph-vessels;
and his conclusions were supported by the investiga-
tions of Pecquet, Bartholin, and Olaus Rudbeck.
The glandular organs were investigated by Wharton,
while Malpighi, Swammerdam, and (in the following
c.) the illustrious Ruysch, by the use of injections
and the aid of the microscope, gave a new impulse to
research in the minute structures. Eminent names
in the history of A. are numerous in the 18th c.
In Ttaly, which still retained its former pre-eminence,
we find Pacchioni, Valsalva, Morgagni, Santorini,
Mascagni, and Cotunni; in France, Winslow,
D’Aubenton, Lieutaud, Vieq d’Azyr, and Bichit,
the founder of General A.; in Germany, the accom-
plished Haller and Meckel prepared the way for
greater achievements in the 19th c.; in Great
Britain, Cowper, Cheselden, Hunter, Cruikshank,
Monro, and Charles Bell contributed to the pro-
gress of the science; while Holland was worthily
represented by Boerhaave, Albinus, Camper, Sandi-
fort, and Bonn. On the boundaries of the two
centuries, we find the names of Sommering, Loder,
Blumenbach, Hildebrand, Reil, Tiedemann, and
Seiler ; nearly all connected with practical medicine,
which was benefited by their studies in A.
The necessity of a union of theory and practice
has led to that zealous study of PATHOLOGICAL A.
(the dissection and study of structures as modified by
diseases) which has recently prevailed. The origin
of this branch of A. may be traced back to ancient
times in Egypt, where post-mortem examinations
were sometimes made to discover the seat of disease
and cause of death. In the medical writings of the
Greeks, some anatomico-pathological observations
are found. During the general revival of science in
the 16th c.. many notices of pathological A. occur.
In 1507, Benevieni of Florence wrote the first book
on this branch of science; and Bonet, in 1679,
published his compilation of numerous observations.
Still, these were only fragmentary indications of a
possible science, and the facts stated were often very
erroneously interpreted. Morgagni (1767), who
must be regarded as the true founder of Pathological
A., was worthily followed by Lieutaud, Sandifort,
Hunter, Baillie, and others. Meckel the Younger,
in Germany, in his study of malformations, &c., paid
little or no attention to practical applications of
the science. The recent change of direction given
to the study of Pathological A., which is now
properly regarded as a means towards practical
improvements in medicine, must be ascribed to
Bichit and the pupils of Broussais, among whom
may be mentioned the names of Laennec, Cruveilhier,
Louis, Andral, Lobstein, Lebert, Virchow, Bennett,
&e. In London and other large towns there are
societies devoted specially to the investigation of
pathology.
CoMPARATIVE A. has always preceded anthro-
potomy, or dissection of the human subject, but was
first treated systematically as a distinct science by
Cuvier and his pupil Meckel the Younger. The
system proposed by the latter was, unfortunately,
never completed. Blumenbach, Tiedemann, Home,
Blainville, Geoffroy St Hilaire, Carus, Oken, Goethe,
the Geerman poet, Richard Owen, John Goodsir, and
Huxley, must be named as eminent contributors to
this branch of science ; while, in late years, zootomy
and comparative A. have been studied, with an
especial reference to physiology, by Miiller, Wagner,
Siebold, Bowman, Todd, and Allan Thomson,
A. For ARrtIsts is studied with reference to the
effects produced by internal structure on the
external form, and describes the organs, especially
the muscles and tendons, not only in a state of
rest, but also as modified by passion, action, and
posture. Consequently, observation of the nude
living form is required in this branch of study,
which has been treated of by Frrard and Genga
(1691); and in modern times, by Lavater (1790),
Camper (1792), Charles Bell (1806), Salvage (1812),
Mascagni (1816), Koeck (1822), Gardy (1831), Fischer
(1838), Salomon and Aulich (1841), Berger (1842),
Seiler and Giinther (1850), &ec.
PrAcTICAL A. includes Dissection (q. v.) and the
making of Preparations. Preparation consists in
dividing parts or organs, so that their respective forms
and positions may be clearly shewn. Organs or parts
thus treated are styled Anatomical Preparations of
bones, muscles, vessels, nerves, &e. For example,
a bone-preparation is made by clearing away all
muscular and other adhesions; the whole structure
of the bones, thus prepared and bleached, when
connected by wires in its natural order, forms an
artificial skeleton.
For preparations of parts containing vessels with
minute ramifications, injections are employed. Some
coloured fluid which has the property of gradually
becoming solid, is gently injected into the arteries
or other vessels by means of a syringe. Formerly,
materials which required a certain degree of warmth
to preserve their fluidity were used; but as these
were attended with inconvenience, a great improve-
ment was made by Shaw and Weber, who intro-
duced the use of linseed-oil and turpentine, which,
when mixed with certain metallic compounds in
due proportions, form a fluid which, after a time,
becomes solid in ordinary temperatures. Quick-
silver and coloured lime-water are also used for
injection of the finer vessels. Preparations are either
dried and varnished or preserved in spirit.
A series of such specimens, arranged in proper
order, forms an Anatomical Museum. The valuable
collections made by Ruysch, Rau, TLoder, Walter,
John and William Hunter, Meckel, Sommering, and
Dupuytren, are all now public property. There
is also a splendid collection in the university of
Edinburgh, collected and prepared for the most part
by John Goodsir. The College of Surgeons of
Edinburgh also possesses a very valuable museum
of pathological preparations. As it is impossible to
preserve thus all parts in their integrity for any
great length of time, artificial copies in wood, ivory,
and wax have been made with great exactitude,
especially in Florence ; and recently Anzou in Paris
has employed papier-mdché for the same purpose.
But, apart from dissections and preparations of
the natural organs, the most general and available
assistance in the study of A. is found in anatomical
engravings and plates on wood and copper. This
assistance was known in ancient times. Aristotle
affixed to his works on A. some snatomical drawings,
which have been lost. In the 16th c., the greatest
artists—Leonardo da Vinei, Michael Angelo, Raphael,
Titian, and Diirer—gave their aid in designing
anatomical figures ; but few of their works, in this
department of art, have been preserved. Lately,
lithography has been employed. Among the numer-
ous illustrations of A. which we now possess, the
