Excerpt from A Manual of Clinical Laboratory Methods IN offering this manual for the use of students and practitioners, the object is to present clinical laboratory methods in concise and accessible form. While devoted largely to a description of methods, the underlying principles, the indications for performing tests and the significance of the results are outlined. Accordingly the plan adopted in most chapters has been as follows: (1) Outline of routine examina tions; (2) description of the simpler qualitative methods which are frequently employed; (3) description of quantitative methods or those of intricate technic; (4) discussion of findings in various morbid condi' tions. When several methods are given, usually the preferred one is indicated. Details are entered into more fully in some cases than in others. For example, the method of counting blood cells has been given meticulously, since it is elementary and its procedures are among the first which must be mastered by the student. It may seem that disproportionate attention has been given to certain subjects, such as the histology and pathology of the blood, but experience in teaching has shown this to be desirable. It is hoped that both 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, will facilitate use of the book in the clinical laboratory. The bibliography, which will be found at the end of the text, contains references to original articles on the newer methods, and will prove helpful to readers desiring to consult the literature. The standard works to which reference is made, have been used freely. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
