SCIENCE 



[N. S. Vol. XXXII. No. 815 



theoretical work as funds and the gifts of 

 apparatus may permit. The laboratory will 

 be open for the use of students from technical 

 institutions already providing elementary 

 classes in the theory of flight, and also for 

 public demonstrations in order to spread an 

 interest in aeronautical science. Men who 

 have undergone courses of training in engi- 

 neering schools, and competent engineers and 

 mechanics, will be eligible as students. The 

 practical work of students will be directed to 

 securing machines ofPering greater stability 

 and trustworthiness, lower power and fuel con- 

 sumption, diminished capital cost and expense 

 of maintenance, and a higher factor of safety 

 than the apparatus now used. In order that 

 an early start may be made, two machines are 

 to be bought at once, and the students will 

 build all further machines, and also those of 

 selected inventors whose ideas are judged to 

 be worthy of construction and practical trial. 

 The funds will be administered by an inde- 

 pendent committee of management, including 

 practical men of science. Mr. Patrick Y. 

 Alexander has oifered to equip the proposed 

 laboratory with the necessary practical appa- 

 ratus. The new institution will probably be 

 called the Rolls Memorial School. 



The approaching exhaustion of the world's 

 richer known lead-producing districts gives 

 special interest to the study of any possible 

 source of lead in countries where increasing 

 prices or improved methods may soon make 

 even low-grade deposits valuable. Accord- 

 ingly the United States Geological Survey 

 has published a report by L. J. Pepperberg on 

 the little-known lead field of the Bearpaw 

 Mountains, in Montana. This report will be 

 contained in the Survey's Bulletin 430, giving 

 the results of some work done by the survey's 

 geologists in 1909, but has also been issued 

 separately in an advance chapter on lead and 

 zinc. The region considered was long ago 

 prospected for gold and silver, but no valuable 

 mineral deposits were found until about 1888, 

 when work was begun on a vein of argentif- 

 erous galena near Lloyd. A claim on this 

 vein was patented in 1892, but work was sus- 



pended because it proved to be unprofitable. 

 Since that time several other claims have been 

 patented and some work has been done, though 

 no ore has yet been produced. The rocks in 

 this region are widely mineralized. The ores 

 were probably deposited by hot waters ascend- 

 ing from great depths. Later, during the 

 long-continued wearing down of the Bearpaw 

 Mountains by erosion and weathering, the 

 metallic minerals were dissolved, carried down 

 again into the rocks by rain water, and rede- 

 posited in concentrated form within moderate 

 distances of the surface. The ore contains a 

 little gold, 40 or 50 ounces of silver to the 

 ton and 50 or 60 per cent, of lead and is 

 easily crushed and concentrated. More thor- 

 ough prospecting in this region may develop 

 ore bodies of greater value. 



UNIVERSITY AND EDUCATIONAL NEWS 

 By the will of the late Mrs. Prances Irving 

 Weston, of Boston, the Massachusetts Insti- 

 tute of Technology is given $10,000 for two 

 scholarships. 



By the will of Mr. Henry Dixon, London 

 University receives £10,000, the income of 

 which is to be used for scientific investigation. 



Dr. Frederick W. Carpenter, of the Uni- 

 versity of Illinois, will spend the coming aca- 

 demic year in Europe on scientific work. His 

 place at the university has been filled by ap- 

 pointment as ad interim instructor, of Mr. 

 William P. Allen, who has been for several 

 years in charge of the biological laboratory 

 maintained by the University of California, 

 at Pacific Grove. 



Dr. Addison W. Moore, professor of phi- 

 losophy in the University of Chicago, will 

 spend the winter and spring at Stanford Uni- 

 versity, to fill the vacancy caused by the ab- 

 sence of Dr. George H. Sabine. 



Dr. Edward F. Malone, of the Wistar In- 

 stitute of Anatomy, has been appointed as- 

 sistant professor of anatomy in the depart- 

 ment of the University of Cincinnati of which 

 Professor H. McE. Knower was recently ap- 

 pointed head.
