270 A. EARLAND I A PLEA FOR A NEW " WILLIAMSON." 



(3) An introductory chapter of the most ample character 

 which should include a p'ecis of the systematic history of the 

 group, and a full account of the life history so far as we know 

 it at present. This chapter should be brought right up to 

 date, so as to include the researches and methods of Lister, 

 Rhumbler, and other modern investigators. This part of the 

 work I should be inclined to regard as of supreme importance, 

 for there is no recent volume on the subject,* and the collection 

 of these facts, which now lie scattered through the pages of the 

 scientific journals of many countries, would in itself earn the 

 gratitude of all English rhizopodists. 



* Since this note was written Messrs. Longmans, Green Sc Co. have 

 published Mr. Chapman's book, " The Foraminifera : an Introduction to 

 the Study of the Protozoa." This excellent work, which is reviewed 

 elsewhere, contains a good, but all too brief account of recent researches, 

 and of the systematic history of the group. Its appearance does not in 

 the least degree affect the question of the need for a new " Williamson."
