%* The exhaustive Monograph on the British Fossil Brachiopoda, of which the 

 present Volume is the last portion, was the result of investigations extending over thirty 

 years. Its author, Dr. T. Davidson, spared neither trouble nor expense in its production, 

 and placed on the lithographic stone with his own hand the Drawings depicted in two 

 hundred and twenty-nine of the Plates employed for the illustration of the first five 

 Volumes. While the accompanying Bibliography (towards the compilation of which Mr. 

 W. H. Dalton had rendered most valuable assistance) was in the press, an unexpected 

 illness caused the active pen to rest, and brought Dr. T. Davidson's life to a close.
