Transcriber’s notes:

The text of this e-book has mostly been preserved in its original
form, including inconsistent italics, capitalisation, hyphenation and
diacritics; however, some infelicities have been corrected silently,
e.g. missing/inconsistent punctuation, parentheses and spacing. Several
footnote markers have been inserted where they were missing from the
text. The _very_ long table of contents has somewhat inconsistent
levels of indentation that don’t correspond accurately with headings
used in the text. Some illustrations have been moved nearer to the
relevant text and their locations may differ from those specified
in the list of illustrations. A few illustrations that lacked an
identifying number have been correctly numbered. The book contains
extensive sections of quoted text but these are identified by square
brackets rather than by traditional quotation marks. Two different
sized fonts were used to print the original body text, a feature that
is replicated in this transcription. Several short passages of text
were inserted by the printer at the last minute, and these are enclosed
in lightly shaded text boxes.

A list of spelling corrections and inconsistencies is appended at the
end of the book.

PREFACE.


The English edition of Braun’s “Die Tierischen Parasiten des Menschen,”
produced in 1906, being out of print, the publishers decided to issue
another edition based on the translation of Braun’s fourth German
edition, which appeared in 1908, to which had been added an appendix,
by Dr. Otto Seifert on Treatment, etc.

When the work was considered with a view to a new edition, it was found
that a vast amount of new matter had to be incorporated, numerous
alterations essential for bringing it up to date were necessitated,
and many omissions were inevitable. The result is that parts of the
book have been rewritten, and, apart from early historical references,
the work of Braun has disappeared. This is more particularly the case
with the Protozoa section of the present work. The numerous additions,
due to the great output of scientific literature and other delays in
publication, have led to the book being somewhat less homogeneous
than we desired, and have necessitated the use of appendices to allow
of the presentation of new facts only recently ascertained. Many new
illustrations have been added or substituted for older, less detailed
ones. Some of these new figures were drawn specially for this book.

The first section, on the Protozoa, has been written by Dr.
Fantham, there being little of the original text left except parts
of the historical portions, and thus the section on Protozoa must
be considered as new. The second section, on Worms (except the
Acanthocephala, Gordiidæ and Hirudinea), has been remodelled by
Professor Stephens to such an extent that this, too, must not be looked
upon as a translation of Braun’s book. With regard to the Arthropoda,
much remains as in the last English edition, but some new matter added
by Braun in his fourth German edition is included, and much new matter
by Mr. Theobald has been incorporated. As regards the Appendix by Dr.
Seifert, the first section has been remodelled, but the sections on
the Helminthes and the Arthropoda are practically translations of the
original.

The authors desire to express their thanks to Miss A. Porter, D.Sc.,
J. P. Sharples, Esq., B.A., M.R.C.S., and H. F. Carter, Esq., F.E.S.,
for valuable help. They also wish to thank the authors, editors,
and publishers of several manuals and journals for their courtesy
in allowing the reproduction of certain of their illustrations. In
this connection mention must be made more particularly of Professor
Castellani, Dr. Chalmers, Professor Doflein, Dr. Leiper, the late
Professor Minchin, Professor Nuttall, Dr. Wenyon, Mr. Edw. Arnold,
Messrs.
