Volumes are issued in paper covers, but may also be obtained bound 

 in buckram at an extra charge per volume, or for part of volume when 

 bound separately. For those who may prefer a card catalogue to a Cata- 

 logue in book-form, copies of every volume specially printed upon one side 

 only of thin paper have been published. The entries can then be cut out 

 and pasted upon cards of any desired size. An extra charge is made for 

 these thin paper copies. 



In the case of Zoology an experiment is being made by offering for sale the 

 separate parts of the volume which correspond to divisions of the animal 

 kingdom. 



Eight complete annual issues of the Catalogue corresponding to the period 

 1901-1908 have now been published. The greater part of the ninth issue is 

 also published. The volumes composing the tenth issue are at present
