Micro-Organisms and their Investigation¹

Abstract

AS the field of bacteriological investigation becomes extended, we have of necessity constant additions to the various methods rendering possible the pursuit of researches in these novel directions, We have only to look at the first edition of Hueppe's “Methoden der Bakterien-Forschung,” published in 1885, consisting of 174 pages, and compare. it with the bulky volume of 488 pages which forms the fifth edition, to see at a glance the advance which has been made in the matter of methods alone. In Flügge's “Die Mikro-organismen” we have another type of book, dealing exclusively with micro-organisms themselves, and the information which has been gathered together concerning them, whilst all details of bacteriological practice are purposely omitted. Dr. Günther has attempted a welding together of these two types of book, special attention being given to microscopical technique with which his name is indeed more particularly associated.
