FOREWORD 



Since 1953 the International Academy of Pathology has held annual 

 courses on the pathologic anatomy and pathologic physiology of various 

 organ systems. Past subjects have included lung, liver, heart, erythrocyte, skin, 

 and bone. The program for each course has been developed by Dr. F. K. 

 Mostofi, Secretary-Treasurer of the Academy, with the assistance of the re- 

 spective moderators. These courses have proved both valuable and increas- 

 ingly popular. For those attending, the material presented by outstanding 

 authorities has been an excellent review of important aspects of normal and 

 abnormal structure, function and development. 



In accordance with the expanding educational activities of the Academy, 

 its Council has decided to sponsor a series of books, Monographs in Pathol- 

 ogy , to publish the material from its courses, which bring together in 

 organized fashion essential information not otherwise so conveniently avail- 

 able. This will give access to the course material to those unable to attend 

 and will provide a lasting source of reference for those who do attend. The 

 many requests for such a publication give the Council confidence that it and 

 succeeding volumes will be useful. 



This initial volume, The Lymphocyte tnul Lymphocytic Tissue, contains 

 the material from the course moderated by Dr. John W. Rebuck at the 1959 

 Academy meeting in Boston. The second monograph will contain the pro- 

 ceedings of the I960 course to be held in Memphis, Tennessee, on "Patho- 

 logic Physiology and Pathology of the Adrenal Cortex," with Dr. Henry 

 Moon as moderator. 



These monographs will contribute to the development of the reference 

 literature in the field of pathology. Manuscripts selected for publication in 

 this series will meet the highest standards of scientific authenticity and edu- 

 cational value. While the first volumes of the Monographs in Pathology will 

 consist of the courses mentioned, the Council of the Academy hopes also to 

 develop other types of monographs by individual authors or in symposium
