IO MARINE BIOLOGICAL LABORATORY. 



were: the Journal of Anatomy; Annual Report of the Progress 

 of Chemistry; Zeitschrift fur Botanik; and the Botanische Jahr- 

 bucher fur Systematik, Pflanzengeschichte und Pflanzengeographie. 

 The new exchanges were: the Philosophical Transactions and 

 the Proceedings of the Royal Society of London, Series B; British 

 Journal of Experimental Biology; Tydschrift der Nederlandisch 

 Dierkundige Vereeniging; Bolletin and Memorias de la Real 

 Sociedad Espanola de Historia natural; Bulletin du Museum 

 National d'Histoire Naturelle; and the Tokyo Botanical Magazine. 

 Our major purchases in books have been Aberhalden's: "Hand- 

 buch der biologischen Arbeitsmethoden, all so far issued; Brandt 

 and Apstein's "Nordisches Plankton," save the three numbers 

 on the Protozoa which we already had ; and the three volumes of 

 Mellor's " Inorganic Chemistry " then issued. 



The binding was extraordinarily heavy this year on account 

 of several unbound sets that have been secured by exchange 

 during the past two years. But we have brought our binding 

 now to a satisfactory relation to current receipts, whereas since 

 1919 we had been in arrears on account of back volumes received 

 after the delay caused by the war. 



The appropriation for the use of the Library for 1923, aside 

 from salaries, was two thousand dollars. Properly there should 

 be added to this the value of sixty-four (64) yearly subscriptions 

 of the BIOLOGICAL BULLETIN that have been used by the Library 

 for exchange purposes. The two thousand was apportioned as 

 follows: current subscriptions, $750; books, $350; Binding, 

 $750; and supplies and express, $150. Though these apportion- 

 ments were not strictly adhered to, the total sum spent, as 

 shown on our Library Account Book, is $1,999.58. The items 

 that ran over our estimate, being subscriptions and books, both 

 due to the very sudden advance in German prices on the change 

 of their method of billing from Marks to Dollars. 



In order to keep up our present subscriptions we shall have to 

 increase our subscription apportionment to the sum of $1,000.00, 

 and even this will not allow us to pay for current subscriptions 

 for the year ahead, as we should like in those cases where we can 

 get accurate bills for these in December. About $200.00 more 

 would be needed in order to start January 1925 with no bills on 

 hand.
