TEE BIOLOGICAL BVILDINO OF THE 

 UNIVERSITY OF WISCONSIN 



Work on the new biological building has 

 begun at Wisconsin University. The struc- 

 ture will occupy a space 42 by 240 feet square, 

 will be built of Madison sandstone and will 

 follow the general style of architecture of 

 University Hall. It is to be four stories high 

 with a basement and sub-basement. 



A room for the study of hibernating animals 

 is to be the most novel feature of the new 

 -structure. Little work on the hibernation of 

 animals has been done by zoologists up to the 

 present time and many interesting findings 

 are anticipated when work begins in the new 

 building. Conditions of temperature, mois- 

 i;ure, light, etc., will be kept at a uniform 

 point to insure the best possible environment 

 -for the animals while hibernating. 



Both a vivarium and an aquarium will be 

 installed in the basement where many land 

 and water animals will be kept for purposes 

 of instruction, study and research. In the six 

 -greenhouses, which are to be built adjoining 

 the main building on the south, a number of 

 'very rare tropical plants will be kept. An ef- 



fort to secure data concerning their peculiar 

 characteristics is the object of their culture. 

 The greater part of the main floor will be 

 taken up by the museum. Collections of both 

 botanical and zoological specimens will be in- 

 stalled there. At the rear of the museum will 

 be the entrance to the lecture auditorium. 

 This will be arranged in amphitheater form 

 around a central raised platform, and will 

 seat 500 students. A small room on the main 

 floor will be devoted to the study of the efi^ect 

 of different lights on plants. A special study 

 of the effect of violet rays will be made.

The " prix de Leonide Spendiarow " was es- 

 tablished by a Russian gentleman of distinc- 

 tion who deposited with the International 

 Geological Congress the sum of four thou- 

 sand rubles, the interest to be awarded at the 

 triennial sessions of the congress " for the best 

 work on geological questions designated by 

 the congress." The award is made by an in- 

 ternational committee and was first given to 

 Karpinsky, director of the Geological Survey 

 of Russia; next to Professor Brogger, of 

 Christiania; then to Tschernyschew, the suc- 

 cessor of Karpinsky. At the recent Stock-
