Pathogenic micro-organisms, including bacteria and Protozoa; a practical manual for students, physicians and health officers

Front matter

It has survived long enough for the copyright to expire and the book to enter the public domain. A public domain book is one that was never subject to copyright or whose legal copyright term has expired. Whether a book is in the public domain may vary country to country. Public domain books are our gateways to the past, representing a wealth of history, culture and knowledge that's often difficult to discover.

Marks, notations and other marginalia present in the original volume will appear in this file - a reminder of this book's long journey from the publisher to a library and finally to you.

Google is proud to partner with libraries to digitize public domain materials and make them widely accessible. Public domain books belong to the public and we are merely their custodians. Nevertheless, this work is expensive, so in order to keep providing this resource, we have taken steps to prevent abuse by commercial parties, including placing technical restrictions on automated querying.

Preface To Second Edition

The past few years have added greatly to our knowledge of the two classes of pathogenic micro-organisms, bacteria and protozoa, representing respectively the lowest forms of the vegetable and animal kingdoms. The importance of the protozoa is now recognized, not only because of the diseases known to be caused by them, but also because of their possible connection with the exanthemata and syphilis. In view of these developments it is obviously essential that the student should be instructed in both fields. I believe that the inclusion of both subjects in a single volume offers the advantages of convenience, facility of instruction, and the presentation of comprehensive knowledge. In the present edition the section on the Protozoa, excepting malaria, was undertaken by Dr. A. W. Williams. The chapter on Malaria is from the pen of Mr. L. B. Goldhom, Instructor in Pathology in the University and Bellevue Hospital Medical College. Needless to say, the revision of the part on Bacteria has been thorough, so that the book as a whole endeavors to refiect the latest knowledge in the whole domain. This edition, like the previous one, has been written for the student and physician rather than for the laboratory worker.

In the preparation of this edition I greatly missed the active assistance of Dr. Guerard, whose removal to a distant city prevented his co-operation, except in the reading of the proof. I am also indebted to Dr. Charles Bolduan, Assistant Bacteriologist in the Research Laboratory, for valuable help in preparing this work for press.

I take this opportunity of acknowledging much valuable help from the splendid work on the pathogenic micro-organisms edited by KoUe and Wassermann. Several photographs from their Atlas have been used.
