NOTICES OF NEW BOOKS. 239 



illustrative : " Owing to the discovery in Britain, since the first 

 volume of this monograph was published, of Arcellida belonging 

 to genera not then known to be represented in this country, the 

 list of British genera of the Arcellida on page 37 of vol i. requires 

 revision." 



James Cash, the author of these volumes, appears to have 

 been one of those naturalists whose work is of the patient 

 character, and whose personality is unobtrusive. Mr. Hopkin- 

 son, in his history of the work, writes: —"In November, 1902, 

 amongst the letters written to our late Secretary, the Rev. Dr. 

 Wiltshire, I found one dated 8th July, 1902, commencing thus : 

 ' A life-long friend, Mr. James Cash of Manchester, has devoted 

 thirty years' time, special knowledge, and enthusiasm to the 

 writing of a monograph on the Ehizopoda. He has also done 

 with his own hands an excellent and adequate equipment of 

 plates to illustrate the text, and, I speak as an old Quekett man, 

 these drawings are distinguished by an ideal measure of faithful- 

 ness to nature, loving care, and artistic beauty.'" The work 

 had been offered to two of our chief publishers of natural history 

 books, who, while expressing approval, would not undertake the 

 publication without the author would bear the whole financial 

 risk. Here, again, the Eay Society, by its publication of Mr. 

 Cash's monograph, has proved itself a real patron in natural 

 history. The author, however, died somewhat suddenly in 

 1909, and to Mr. Hopkinson belongs the credit of not only 

 editing this work, but also compiling its extensive synonymy. 



This second volume contains plates xvii. to xxxii., many of 

 which are coloured, besides numerous figures in the text.

Theee can be no doubt that this newly appointed Research 

 Committee should effect quite a revolution in our knowledge of 

 the economic entomology of Tropical Africa. Under the presi- 

 dency of the Earl of Cromer an influential Committee has been 

 formed, some members of which are well-known economic
