New Texts 



■A Manual of Clinical Laboratory Methods New 



IN this, the newest book on the subject, clinical laboratory methods are presented in concise 

 and accessible form. While devoted largely to description of methods, thorough attention 

 is given to the underlying principles, the indications for performing tests and the sigiiificance 

 of the results. In most chapters the plan is as follows, (i) Outline of routine examinations; 

 (2) description of the simple qualitative methods which are frequently employed; (3) descrip- 

 tion of quantitative methods or those of intricate technic; (4) discussion of findings in vari- 

 ous morbid conditions. When several methods are given, usually the preferred one is indi- 

 cated. The method of counting blood cells has been given meticulously, and special atten- 

 tion has been .given to the histology and pathology of the blood. Chemical examination of the 

 blood and urine and the relations of urine examinations to life insurance are also treated 

 very fully. The section on Serum Reactions is, in effect a monograph on the Widal, Wasser- 

 mann and related tests. The liberal use of cross references in the body of the text and the 

 synoptic resumes of quantitative procedures in the chapters on Blood and Urine greatly facili- 

 tate the use of the book in the clinical laboratory. 



Chapter Headings: Examination of the Blood — Examination of Urine — Examination of 

 Gastric and Duodenal Contents — Examination of the Feces — Examination of Sputum — Ex- 

 amination of Body Exudates, Fluids and Miscellaneous Methods — Bacteriological Methods — 

 Appendix (Equipment, Stains, Vaccines — examination of a large number of specimens, etc.).

New 



ANEW TEXT by a distinguished authority which, because it deals with the two most in- 

 teresting phases of botany, will achieve the very desirable effect of securing the stu- 

 dent's earnest attention. The text is complete and with a logical arrangement that will ap- 

 peal to all teachers of the subject and is largely illustrated with photographs from Nature.

KENDALL— -Bacteriology, General, Pathological and Intestinal 



New 



(2;;d) Edition 



ONE of the achievements of the Great War is a noteworthy advance in the Science of 

 Bacteriology. This is manifested not only in marked improvements in methods of in- 

 vestigation and in modifications of preexisting views in the important fields of Infection and 

 Prevention of many diseases, but also in a complete revision of some of the more important 

 groups of bacteria. Prominent among these is the great class of anaerobic bacilli. During 

 the war period, furthermore, much additional information has accumulated pertinent to dis- 

 eases which have hitherto been elusive. These developments have necessitated the rewriting 

 of entire sections of this book, and extensive changes and additions to nearly every chapter. 

 Indeed, including the anaerobes and the work on spiral organisms, this new edition contains 

 as much as any volume in existence of the worth-while war and post-war work. 



The text retains that characteristic which contrilmted so largely to the success of its first 

 edition, namely, dynaime iiifcrprctafioii of the subject. The author emphasizes throughout 

 zi'hat bacteria do rather than wliat tlicy are — how they get into the tissues — what they feed 

 on — what they excrete — how they multiply — how they escape from the body — the chemistry 

 of bacterial activity. 



New methods of handling bacteria, methods which are improvements over earlier ones, 

 details of laboratory equipment, the minutiae of technic and the use and value of apparatus 

 are carefully consdered. Much space is given to the discussion of the applications of bac- 

 teriology in Etiology and Preventive Medicine, as well as Serology and Vaccine therapy.
