Preface to American Edition. ix 



verbiage of the translation has sometimes, in the endeavor to keep 

 close to the original, come to be somewhat complicated for English 

 text. The editorial notes, which are always enclosed in special 

 brackets ([ ]), have purposely been kept within brief limits, 

 because of our realization of the sufficiency of the work for the 

 introductory purposes for which it is intended by the author, and 

 because of a desire to keep the size of the book near the limits 

 of the original edition. We feel that for use at the hands of 

 graduate physicians the book as it stands meets the purpose for 

 which it was written ; for student purposes, as a handbook as 

 well as a general text, it would perhaps have been regarded as 

 an advantage to have added descriptive matter to the tables of 

 the vegetable and animal parasitic organisms and to have ex- 

 panded the text somewhat in connection with minute anatomy, 

 thus giving it a fuller adaptation to laboratory studies. A num- 

 ber of illustrations have been generously added by the publishers 

 with this latter view in mind. These illustrations, made by the 

 well-known artist, Louis Schmidt, include figures 63, 82, 86, 89, 

 91, 97, loi, 102, 103, 104, III and 125; and it is thought that 

 the book, with such additions, will find a fuller place as an aid to 

 the student in the laboratory of pathological histology. 



The publishers have not spared expense to make this work 

 possible in the translated form, and by their interest have, we 

 feel, placed the profession under obligations. For ourselves the 

 venture is in no sense a financial one, and if others will find, as 

 we hope, that our efforts have aided in pressing forward the 

 general good for both veterinary and human medicine, our com- 

 pensation will be ample.
