Bacteria
Author: George M. Sternberg

PREFACE TO SECOND EDITION. THE First Edition of Bacteria being nearly ex- hausted at the end of six months from date of publica- tion, the writer has taken advantage of the opportunity which this favorable reception of the work hac given him, and has revised and added to the text, with a view to making it still more worthy of a place in the libr... more »aries of physicians, and of others interested in this important field of investigation. Several of the plates have also been remodelled, and new photo-micrographs introduced in place of some of those in the first edition, which have been excelled by later efforts. The bibliography has also been brought up to date. It has been thought best in the present edition to remove the name of Dr. Magnin from the foremost place upon the titlepage, inasmuch as the present writer has contributed more than two-thirds of the text, and as the illustrations from nature photo-micrographs are all his work. The appreciation in which Dr. Magnins systematic account of the bacteria is held is shown, however, by the fact that we have not attempted to re-write this portion of the work, at the head of which a separate titlepage, bearing Dr. Magnins name, will be found. . THE work of Dr. Magnin, which was published in Paris in 1878 and translated by the writer in 1880, gave an admirable resume of our knowledge of the Bacteria at the date of its publication. But very consid- erable progress has been made since, especially as regards methods of manipulation, the comparative value of various chemical reagents as germicides and antiseptics, and the role of the Bacteria in infectious diseases. With a view to keeping the work fully up to the progress of science in this direction, the writer has added a chapter upon each of these subjects, and one upon Bacteria in Surgical Lesions Parts Third, Fourth, Fifth, and Sixth. His name, therefore, appears upon the titlepage as one of the authors of the present volume. It has not been considered necessary, however, to rewrite the chapters on Morphology and Physiology Parts First and Second. It is true that the classification of Cohn, which was very properly adopted by Professor Magnin, is only provisional, and that certain recently discovered pathogenic species are not included. But these will receive attention in Part Fifth of the present volume and it would be premature to attempt a natural and permanent classifica- tion of these minute plants, which are now engaging the attention of numerous investigators in all parts of the civilized world. For the present we probably can- not do better than to adhere to the artificial classification, based upon morphological characters alone, which Cohn has given us. It must be remembered, however, that SPHERO- BACTERIA micrococci are not always round that there is no well-defined line of demarcation between the MICRO-BACTERIA and the DESMO-BACTERIA, between the genus BACTERIUM and the genus BACILLUS, or between the last-named genus and the LEPTOTHRIX...
