ACKNOWLEDGMENTS 
Finally, it is appropriate to extend our deep appreciation to Mr. E. Theel 
and Mr. K. Fischer for their meticulous draftsmanship and their ability to com- 
prehend the scientific intent of projected illustrations in preparing the anatomical 
drawings. Also especially deserving of our indebtedness are Mr. W. Fischer and 
Mrs. A. Boysen for assistance in obtaining optimal macroscopic pictures and for 
making slides and prints. We are also grateful to Naoma Crisp-Lindgren who 
has translated the text. To our many colleagues of the Abteilung fur Experi- 
mentelle Pathologic who critically advised and supported the production of this 
work, as well as having helped sustain our enthusiasm, we remain profoundly 
grateful.
