3 volumes in one, 8o (222 x 144 mm). Tinted lithograph after Cohn (Part I); tinted lithograph after Cohen, and a colored lithograph after Cohn, Kirchner, and Weigert (Part II); colored lithograph after Cohn and Robert Koch (Part IV). Bound with Vol. III of Beitrge zur Biologie der Pflanzen in modern half morocco gilt. Provenance: Charles S. Dolley (b.1856), translator of one of Cohn's works, one of the earliest English translations of a bacteriological work produced in America (signature on title of Vol. I).

Second edition of "Untersuchungen ber Bacterien"; FIRST EDITION of other articles. Cohn's three papers, published in the journal that he founded and edited, are seminal works of bacteriology. His first paper, first published in 1872, was effectively the begining of the science of bacteriology, and in it Cohn categorized 4 groups of bacteria according to shape. The second paper described spores that could resist very high temperatures (and whose existence had fueled the theory of spontaneous generation), and the third paper included an introduction to the work by Robert Koch, Aetiologie der Milzbrand-Krankheit which immediately followed. Koch finished the series of Untersuchungen ber Bacterien, as author of parts V, VI, and VII. Garrison-Morton 2483; Norman 494.
