Miscellaneous Scientific Intelligence. 519 



Lippincott Company. Price $5.00). — The subject of immunity- 

 lias as yet only comparatively few years of scientific study to its 

 credit. Much of our knowledge regarding infection and resist- 

 ance to disease is in a state of flux, the generalizations being 

 modified frequently with the advent of new information from the 

 laboratory and the clinic. At a stage such as this a concise guide 

 to the newest contributions — a readable review which is some- 

 thing more than a compilation of experiments or a series of 

 abstracts — is eminently desirable. This new volume seems to 

 serve well the purpose of introducing beginners in its field to the 

 achievements and problems of immunology which are now-a-days 

 written in a language that only the specially tutored can grasp. 

 The reviewers predict a large usefulness for the book.

3. Microhiology : third edition; edited by Charles E. Mar- 

 shall. Pp. xxviii, 1043. Philadelphia (P. Blakiston's Son & 

 Co. Price $4.00 net). — This book represents contributions by 

 25 well-known workers in the domain of bacteriology and related 

 subjects under the editorship of Director Charles E. Marshall of 

 the Massachusetts Agricultural College. The fact that it has 

 already passed through two earlier editions attests its popularity 

 as a textbook and volume for handy reference. Compilations pre- 

 pared jointly by many writers are only rarely satisfactory to a 

 critical reviewer. They often lack symmetry in treatment and 

 continuity in argument or exposition. Whatever shortcomings 

 Marshall's Microbiology may have in this respect are counterbal- 

 anced by the expert opinions of the various contributors. The 

 range of topics is large, dealing not merely with the morphology 

 of microorganisms, but also with their physiology and the role 

 which they may play in relation to human, animal and plant 

 welfare. l. b. m. 



4. Bihliotheca Zoologica II. Verzeichnis der Schriften ueher 

 Zoologie luelche in den periodiscJien Werken enthalten und vom 

 Jahre 1861-1880 selhstdndig erschienen sind; bearbeitet von Dr. 

 0. Taschenberg. Lieferungen 21 to 23. Leipzig, 1921 (Wil- 

 helmEngelmann). — The nineteenth part of the great work edited 

 by Dr. Taschenber-g was issued in 1913 (see this Journal, vol. 35, 

 pp. 558, 559). Part 20 has been published but has not as yet 

 been received; presumably it was lost in the mails during the 

 early part of the war. The three parts now in hand embrace 

 signatures 755 to 784, or pages 6073 to 6312, all belonging to the 

 supplements of the original work. The second half of the sev- 

 enth volume includes signatures 745 to 777, pp. 5515 to 6256; 

 it bears the dates 1913 to 1921. 



It is gratifying that a work so important to all zoologists and 

 so comprehensive in character should have been carried on to 

 this point and be now approaching completion. The brief intro- 

 duction of the editor to this seventh volume expresses feelings 

 which must be shared by all loyal workers in zoological science 

 to whatever country they may belong.
