FOREWORD TO VOLUME II 



The unexpected and deeply regretted death of Dr. Ivimey-Cook took place 

 in February 1952, just after the publication of Volume I. This was not 

 only a serious loss but it has thrown an additional burden on the surviving 

 author which is to some extent responsible for the delay in the appearance 

 of this Volume. Only a part of the manuscript had been prepared before 

 Dr. Cook's death and the completion of the book without his able and 

 careful collaboration has taken longer than was anticipated. 



It is not proposed, however, to abandon the preparation of the two 

 remaining Volumes of the complete work. They will continue to bear our 

 joint names, as Dr. Cook left a considerable amount of material intended 

 for these Volumes, particularly a draft of an important section on Economic 

 Botany, which was the product of wide experience and study. Notwith- 

 standing the increased difficulty of the task it is hoped that, if fate is kind, 

 the work may be finished without too great a delay.
