EXAMINATION OP URINI

Preface To The Third Edition

But a short time has elapsed since the issue of the second edition of this book. No extensive additions or alterations have therefore been made, while some less important parts have been omitted, with a view to keei)- ing the size of the volume within its original limits. Opportunity has however been taken to correct some inaccuracies as well as typographical errors which were more numerous than they should have been in the last edition, owing to the pressure of other engagements while reading proof. The proof of this edition has been read during odds and ends of time otherwise fully occupied, but it is hoped it will be found tolerably free from errors. A few new cuts have been introduced chiefly to replace older more unsatisfactory ones.

I am indebted to my colleague Dr. Wormley, Professor of chemistry in the University of Pennsylvania, for many practical suggestions.

Preface To The Second Edition

Advantage has been taken of the occasion for a new edition of this little work, to carefully correct the previous one, as well as to improve it by incorporating such additions of new facts and ])rocesses as seemed consistent with its original purpose, without, however, increasing the size of the book. This has been accomplished by slightly increasing the amount of matter on each page.

It is hoped that it may prove worthy of the same kindly reception accorded its predecessor.

Preface To The First Edition

Doubtless it will be thought by some that there is no [)resent necessity for an additional volume on the subject which the title of this pretends to cover. Such was, indeed, the writer’s own impression, when urged, a few months ago, to prepare it. Some reflection, howevei’, (convinced him that, while there were quite a number of comprehensive works of great value, and a smaller number of manuals or guides for the examination of urine, the latter seemed altogether too limited, while the former are too bulky to be convenient for daily use. It was further thought that an experience of several years in alngiost daily microscopical and chemical examinations of urine for others and himself, as well as in teaching the subject in the University of Pennsylvania, had given the author such familiarity with the ]>ractical wants of the physician, as would appear to justify his attempting to supply them in a convenient shape.
