time in the mines of Lake Superior, and the 

 largest recorded was found in 185Y in the 

 Minnesota mine. It measured 45 feet in 

 length, 22 feet at its greatest width and more 

 than 8 feet at its thickest part, and contained 

 over 90 per cent, pure copper. The total 

 weight was about 420 tons. 



The Observatory gives the following from 

 the Daily Chronicle, a leading London paper: 



Actors and others are discussing what they shall 

 do with the seventh day. There is a tiny island in 

 the South Pacific where there is no seventh day, 

 six days being the allotted span of every week. 

 All travelers know that time is lost or gained in 

 traveling east or west, and Chatham Island is just 

 on the line of demarcation between times and 

 dates. To keep in line with the almanac, there- 

 fore, the plan has been adopted of jumping the 

 afternoon of one day and the morning of the next 

 in every week, so that the islanders commence 

 Wednesday, but at 10 o'clock switch on to Thurs- 

 day afternoon. 



UNIVERSITY AND EDUCATIONAL NEWS 

 The children of the late James Dwight 

 Dana (Silliman professor of geology at Tale 

 University from 1850 to 1895) have ofEered to 

 establish a fund which shall ultimately reach 

 $24,000, the income to be used "to further 

 study and research in geology." 



By the will of Frederick Blanchard of 

 Tyngsboro, Harvard University receives for 

 the use of the Museum of Comparative Zool- 

 ogy his entomological collection. 



Mrs. John Joseph Albright, of Buffalo, a 

 trustee of Smith College, has given $60,000 

 toward the million-dollar fund. This gift is 

 to establish what will be known as the S. 

 Clarke Seelye professorship. The subscrip- 

 tions now amount to about $500,000. 



The corporation of Yale University has 

 passed a statute regarding sabbatical years, 

 making it possible for a professor or assistant 

 professor to take a half-year's absence on full 

 salary as an alternative for a full year at half 

 salary. A similar plan was adopted by the 

 trustees of Columbia University several years 



Enrollment figures for 1912-13 for all de- 

 partments of Western Eeserve University are 

 announced this week at the university as fol- 

 lows: Adelbert College, 456; the College for 

 Women, 354; the Graduate School (incom- 

 plete), 14; the Medical Department, 168; the 

 Law School, 130; the Dental School, 12Y; the 

 Library School (incomplete), 50, and the 

 School of Pharmacy, 111. The total enroll- 

 ment for all departments is 1,410. Western 

 Eeserve University, in its undergraduate de- 

 partments, Adelbert College and the College 

 for Women, has decided that, under ordinary 

 conditions, no division of a class for recita- 

 tion purposes is to exceed twenty-five persons. 

 This vote, applying to all classes, means that 

 in the freshman class of Adelbert College 

 there will be seven divisions, and in the fresh- 

 man class of the College for Women five di- 

 visions in all required subjects. Many large 

 elective classes will be divided into two, three 

 or four divisions.

radiotelegraphio achievements by the poul- 



sen system 



To THE Editor op Science : I wish to call at- 

 tention to the important results being accom- 

 plished in this country by the Poulsen system 

 of wireless telegraphy. This system and the 

 work that is being done by it is of great sci- 

 entific interest as well as practical importance, 

 and inasmuch as almost nothing is generally 

 known about it a brief account of its main 

 features may be of interest to the readers of 

 Science. Although not a physicist I am led 

 to call attention to this subject because I have 

 waited in vain to see any mention of it in 

 scientific journals, and because numerous 

 students of related subjects whom I know
