SCIENCE. 



Pursuant to recommendations by Chancel- 

 lor Andrews and the board of regents, the 

 state legislature early in 1905 voted the sum 

 of fifty thousand dollars for the erection of a 

 portion of the first wing of a fireproof mu- 

 seum. With the assurance of safe and ample 

 room and increased facilities Mr. Morrill 

 again offered substantial support to the 

 amount of one thousand dollars annually for 

 paleontological research and exploration. 



This is an important sum, especially to a 

 young institution and to those living near the 

 fossil fields where student labor is to be de- 

 pended upon, and where through friendly in- 

 terest in scientific investigation the railroads 

 of the commonwealth stand ready to extend 

 to the university free transportation and other 

 courtesies. 



Early in the summer a small party of 

 students was organized, and, in response 

 to invitations from Mr. James Cook, of 

 Agate, Nebr., camped and collected on his 

 extensive ranch, which includes some twelve 

 miles of Loup Fork exposures along the Nio- 

 brara River. The season was spent at one 

 spot where, in a thin layer, the bones occurred 

 in such numbers that they were literally quar- 

 ried. As heretofore the Burlington and Mis- 

 souri River Railroad offered free transporta- 

 tion for men and material. 



Personnel of the tenth expedition : L. J. 

 Pepperberg, H. J. Cook, M. L. Lee, J. H. 

 Miller, W. D. Steckelberg and the writer, who 

 was in charge. 



Field work in iSTebraska is not necessarily 

 confined to summer, for fall is a pro- 

 tracted and open season, and many excur- 

 sions are yet to be made before the year 

 ends. Collections of the economic resources 

 of the state at- large are being made by Dr. 

 George E. Condra. Special collections of the 

 economic resources and fossils of Sarpy 

 County are being made by Mr. L. J. Pepper- 

 berg, and the work of collecting is now being 

 extended to eastern and southern fields by 

 Mr. Charles N. Gould, professor of geology in 

 the University of Oklahoma, while pursuing 

 courses of study leading to his doctorate. 



Plans for a new state museum are drawn 

 and approved, and it is promised that the first 



portion of a fire-proof wing will be ready for 

 occupancy within a year. 



This, coupled with the fact that funds are 

 available from several sources, brightens the 

 outlook for geological and paleontological 

 work in the University of Nebraska, where 

 for the past year more than one ton a week 

 of the best state collections have been boxed 

 and lowered in an abandoned steam tunnel 

 under the campus.

REPORT TO TBE TRUSTEES OF THE ELIZA- 

 BETH THOMPSON SCIENCE FUND OF 



PROFESSOR BOVERI'S RESEARCHES. 

 The following report has been received from 

 -Professor Boveri and is now published by 

 order of the trustees : 



I herewith permit myself to make report 

 concerning the investigations which I have 

 carried out with the support of the Elizabeth 

 Thompson Science Fund. I spent seven weeks 

 at the Zoological Station in Naples, where I 

 occupied myself, in connection with earlier 

 experiments, on the development of dispermic 

 sea urchin eggs with the following questions: 

 1. It is of fundamental importance for 

 the whole problem of dispermy to determine 

 whether dispermic germs develop patholog- 

 ically because they have taken in two sperma- 

 tozoa or because they were already patholog- 

 ical. I have, therefore, tested this question 

 experimentally. One of the experiments suc- 

 ceeded in every respect so perfectly that the 

 assertion can now be made with complete cer- 

 tainty that the same egg which, if impreg- 

 nated by a single spermatozoon would have
