PREFACE.
   The multitude of technical term's, which encum-
 ber and deform the science of Medicine in all its
 departments, constitutes the most formidable diffi-
 culty in the way of its cultivation, and one which
 the student encounters at every step, especialty in
 the earlier period of his pupilage.  In every book
 he reads, in every lecture he hears, there are terms
 and phrases which  belong exclusively to medical
 technology.  Nor does any previous literary train-
 ing prepare him for understanding them, for the
 reason that our nomenclatures are not constructed
 upon any common principle, or derived legitimately
 from any  one of the learned languages, but are
 lieterogeneouslyand arbitrarily adopted from nearly
 all the tongues of our babbling earth, and, as has
been truly said, " most barbarously and  illegiti-
mately compounded."
  The  attempts perennially  made  to  introduce 
VI
PREFACE.
new nomenclatures into the several branches  of
medical science, while they exhibit a conviction of
the evil, have thus far  failed to remove it, nume-
rous barbarous and erroneous terms being retained
in preference to those more classical and correct.
Hence it is that  the stumbling-blocks in the path
of the student are increased by every new adven-
turer in Neology,  whose innovations are proposed
in this department.
  To diminish the number  of ambiguous and un-
pronounceable technicals, would indeed be a desi-
deratum, and yet  the pedantry and false pretension
of medical, exclusives, who still abound in the
profession,  would frown upon any such  effort  to
popularize  the science.   Still, however, it may be
lawful to attempt the exclusion of obsolete though
ancient terms, multitudes of which are not found
in any modern standard author,  nor employed by
any public lecturer in the United States.
  In the present work, this  latter attempt has been
made, and  with what success the  profession will
judge.  For the  more ancient terminological no-
menclatures and obsolete technicalities, the student
will find occasion  for reference to the larger works
of Motherby, Parr, Fox, Morris, Quincy, Hooper,
Coxe, Dunglison, Hoblyn, Ac.  But he will seldom
be disappointed  in this little manual, should  he

 search for any term retained by modern authors,
 or employed by his teachers  during his collegiate
 course.
  The surprising number  of  synonyms still  found
 in medical books,  and  therefore retained here,
 demonstrate that the  technology of  our science
 might be still further condensed, and the monstrum
 horrendum of hard words, still placed at the por-
 tals  of our science, as if to  forbid the  approach
 of the novitiate, could be readily  and usefully
 reduced  within  much  smaller  compass.   This,
 however, could  not safely be done, until, by com-
 mon  consent,  the  profession  shall adopt  some
 uniform standard, and no longer call diseases and
 remedies by so many different and even barbarous
 names.
  The design being to bring this Lexicon within
 the smallest possible compass, and adapt it  to  the
 use  of students, as  a Pocket  Companion,  the
 briefest possible definition has been given in every
 case,  consistent  with  perspicuity;  omitting  all
 reference to the etymology of the terms, for which
 larger works may be  consulted, and  which will
 still be needed in every medical  library. In  the
 department of derivation, the late work of Professor
Dunglison leaves nothing to be desired.
  It  is simply as a vocabulary of definitions that

the present vade-mecum is  commended to  the
profession and the  public, without any  claim of
novelty or other merit, except convenience, brevity,
simplicity,  and accuracy.  If in these attributes
it  shall be deemed worthy of approval,  it cannot
fail to be useful as a help to students and junior
practitioners, for whose  benefit it has been  pre-
pared, and to whom it is affectionately  inscribed
by the Author.

    PREFACE TO THE SECOND EDITION.


   The demand for this little pocket Lexicon, since
 the former edition has been exhausted, renders  it
 imperative upon  the  author to correct, improve,
 and enlarge the work, before again committing  it
 to  the press.  The changes  and improvements
 which are perennial in every branch of the healing
 art, are, of necessity, suggestive  of  new techni-
 calities ; while there are not a  few among medical
 writers and teachers who seem  ambitious to extend
 our already  overburdened nomenclature  by the
 introduction  of new terms, even in the absence of
 anything else new, in their contributions to profes-
 sional literature.  Hence, the office of the humble
 lexicographer imposes upon him the duty of col-
 lecting and defining these in every reprint  of his
 book,  a  task which has been performed in the
present instance, as it  is hoped, to  the full extent
desirable in such a dictionary.  Thus improved
and enlarged, it is again submitted to the profes-
sion and the public, by
                                The Author.
