PEEFACE 



The classical volume of Dr. AY. B. Carpenter, written 

 in conjunction with Professors Kitchen Parker and 

 Rupert Jones, is still an exceedingly valuable book 

 for workers in this special branch of study, for it 

 contains the pioneer work of those authors on the 

 morphology and microscopic shell structure of 

 Foraminifera.^ The monographs of Drs. W. C 

 Williamson- and H. B. Brady'' are also indispensable 

 as works of reference. But these and others more 

 recently published are voluminous and not always 

 easily accessible to the student ; whilst the increas- 

 ingly large number of smaller works on the subject, 

 written by Continental, English, and other authors, 

 which have from time to time appeared in the 

 various publications of Scientific Societies and in 

 periodicals and journals, are quite outside the scope 

 of the general student's reading.^
