 Among others, there is a first edition of 

 Euclid's " Elements," a Pacioli of 1494 and

We learn from the Princeton Alumni Neivs 

 that at the new vivarium, which is now in use 

 by the department of biology, the salt water 

 tanks have been filled with sea water. A tank 

 steamer was sent out to sea and brought in a 



fresh supply of water, which was transferred 

 to Princeton by tank ear and carried in water 

 carts to the vivarium. By means of the cir- 

 culating and filtrating system of the vivarium, 

 this water can be used over and over again 

 without detriment to the fish in it. Professor 

 E. G. Conklin, who is in charge of the vivar- 

 ium, has returned from a year's leave of ab- 

 sence, most of which he spent at the Marine 

 Laboratory at Naples, and the work of stock- 

 ing the vivarium is now under way. 



The states of the South African union will

 and transporting it to England. The latter 

 part of the task will be under the superintend- 

 ence of the Zoological Society of London, in 

 whose menagerie it is hoped that the whole 

 collection will be ready for exhibition next 

 summer, under the title of the King's African 

 Collection.
