CONSPECTUS OF THE LITERATURE 

 AND NOTES. 



1. For the general literature of the Bacteria see de Bary, Comparative 

 Morphology and Biology of the Fungi, Mycetozoa, and Bacteria, Clarendon 

 Press, 1887, and W. Zopf, Die Spaltpilze, 3rd edition, Breslau, 1884. — 

 The works of Pasteur, F. Cohn, v. Nagell, van Tieghem, R. Koch, Brefeld, 

 A. Prazmowski, Fitz, must be specially mentioned here as laying generally 

 the foundations of our knowledge ; they are cited in the works above-named, 

 and some of them again below. — Duclaux, Chimie biologique, Paris, 1883, 

 gives an elegant account of the views and methods of the French school, 

 and especially of the school of Pasteur; F. Hueppe, Die Methoden d. 

 Bacterienforschung (3rd ed., 1886), gives hints for the conduct of investigation 

 according to the method perfected especially by R. Koch. — Writers on 

 General Morphology and Classification are F. Hueppe, Die Formen d. 

 Bacterien &c., Wiesbaden, 1886; J. Schroter in the Kryptogamenflora v. 

 Schlesien, ed. F. Cohn, Bd. Ill, 2 Lieferung, pp. 136-172. This work gives 

 a good classification and description of most known forms ; it reached me 

 while the present work was in the press, and it was hardly possible for me 

 to make any use of it. — Of the many general Text-books of Bacteria of 

 recent date may be mentioned : C. Fliigge, Fermente n. Mikroparasiten, in 

 V. Pettenkofer and v. Ziemssen, Handb. d. Hygieine (the second edition 

 with the title. Die Mikroorganismen, Leipsic, 1886, came out while this 

 work was being printed) ; E. M. Crookshank, Introduction to practical 

 Bacteriology, London, 1886 ; and a copious Text-book of the Bacteria of 

 Disease, by Comil et Babes, Les Bacteries et leur role dans I'anatomie et 

 I'histologie pathologiques des maladies infectieuses, 2nd ed., Paris, 1886. 

 With these may be coupled the Jahresbericht ii. d. Fortschritte d. Lehre v. 

 d. pathogenen Mikroorganismen of P. Banmgarten, Erster Jahrg. 1885, 

 Braunschweig, 1886, of which I have made frequent use, and to which 

 I here refer the reader once for all for the more recent special literature.
