PREFACE TO VOL. II. 



The account of the Zoological collections has taken so long in 



preparation, and is so bulky, that it is considered convenient to 



issue the special accounts of the several collections written by the 



Assistant Keepers and Assistants who are in charge of those 



collections, without further delay, as Vol. II. of the History. 



An account of the General History of the Zoological Department 



is in the press, and will be issued as Vol. III. as soon as revised 



and completed.
