iv FOREWORD 



here, though to some extent arbitrary, may be said to give a fair repre- 

 sentation of the most active areas of research at the present time. 



I should Hke to take this opportunity to express my personal gratitude 

 to the other members of the committee for their helpful cooperation in 

 planning the meeting, and in the preparation of this volume ; to Miss 

 Marjorie Foxworthy (now Mrs. Charles Turbyfill) for her many services 

 before, during, and after the meeting; to Mr. Robert P. Bronson for his 

 help with travel arrangements; and to my students, A. S. Hu, R. M. 

 Myers, J. H. McAlear, and R. V. Crisera, for their help during the meet- 

 ing. Mr. George N. Belknap, University editor, and Mr. Donald Shep- 

 ardson, superintendent of the University Press, have been very helpful 

 in seeing the book through the press.
