The Zoological Record. 



Owing to the collapse of the International Catalogue of Scien- 

 tific Literature in connection with which the Record was published 

 from 1906 to 1914 the Zoological Society of London has under- 

 taken to bear the whole financial responsibility for the prepara- 

 tion and printing of the Record. 



Owing to the great increase of the cost of printing and to 

 the very meagre support accorded to the Record by Zoologists 

 and Zoological Institutes generally, the financial burden of this 

 undertaking on the Zoological Society is becoming very severe. 

 The cost of printing the Record now amounts to between ^jT 1.500 

 and £ 2.000 annually and the Society receives back by Subscri- 

 bers and sales less than 25% of this sum; I fear therefore, un- 

 less Zoologists are prepared to make greater efforts to support the 

 undertaking, there is a strong possibility that the Council of the 

 Zoological Society may refuse to find this large sum each year. 



It appears therefore to be the duty of every Zoologist to help 

 so far as he is able to support this most invaluable work. All 

 particulars and forms of subscription can be obtained from the 

 Secretary of the Zoological Society, Regents Park, London N, W. 8., 

 but I amy mention that the price of the whole volume is now 

 £ 2.10.0 and the price of the^ separate parts a proportional 

 smaller sum.
