Professor D. T. Gwynne-Vaughan, pro- 

 fessor of botany at University College, Eead- 

 ing, died, on September 4, at the age of forty- 

 four years. 



J. U. T. QuENSEL, professor of pathologic 

 anatomy and hygiene at the University of 

 Upsala, has died at the age of seventy-five 

 years. 



Dr. Theodor Albrecht, of the Potsdam 

 Geodetic Institute, head of the International 

 Bureau for Geodesy, has died at the age of 

 seventy-two years. 



Among those who have been killed while 

 tending the wounded in the field are G. Hei- 

 mann, of Berlin, one of the pioneers in eugen- 

 ics, and Professor H. Piper, of the Institute 

 for Physiology, Berlin. Dr. Piper's work was 

 on the physiology of the senses. 



The A m erican Academy of Arts and Sci- 

 ences receives the sum of $3,000 under the 

 will of William Watson, of which he was sec- 

 retary. Mr. Watson's scientific books and in- 

 struments are to be divided among the acad- 

 emy. Harvard University and the Massachu- 

 setts Institute of Technology. 



It is stated in Nature that at the sale by 

 auction of the Amesbury Abbey estate on Sep- 

 tember 21, the historic monument of Stone- 

 henge was purchased for £6,600 by a local 

 landowner, Mr. C. H. E. Chubb, of Bemerton 

 Lodge, Salisbury. The estate came into the 

 market in consequence of the deaths of Sir 

 Edmund Antrobus and of Ms only son, who 

 was killed in action last October. As Stone- 

 henge is under the protection of the ancient 

 monuments act, no steps can be taken by the 

 owner to alter or remove any parts of this re- 

 markable relic of antiquity. 



The Botanical Society of Pennsylvania held 

 its twelfth annual scientific assembly in Bo- 

 tanical Hall on Saturday, October 2. The 

 program included illustrated lectures by H. H. 

 M. Bowman and Mr. W. E. Taylor, the former 

 on " Botanical Experiences Along the Keys of 

 Southern Florida " ; the latter on " Summer 

 Botanizing on Mount Desert." Dr. Joseph S. 

 Hepburn explained his "Experiments on the 



Digestive Action in the Pitcher Liquids of 

 Nepenthes." 



We learn from Nature that the members of 

 the Siberian Expedition sent out sixteen 

 months ago, at the joint expense of the Oxford 

 University School of Anthropology and the 

 University of Pennsylvania Museum, reached 

 London last week. The leader. Miss M. A. 

 Ozaplicka, is a native of Eussian Poland, and 

 has been a student of the Warsaw University 

 and of Somerville College, Oxford. The expe- 

 dition consisted of Miss Curtis, the artist. 

 Miss Haviland, ornithologist, and Mr. Hull, of 

 the University of Pennsylvania, ethnologist. 

 They proceeded from Warsaw to Krasniack, 

 in Siberia, and thence to the mouth of the 

 Yenisei. The first tribe examined was that of 

 the Samoyeds, and then the winter was spent 

 among the Tungus of the Tundra, a very prim- 

 itive race, little influenced by Eussian culture. 

 The spring was devoted to the Tartars, who are 

 much more civilized than either the Samoyeds 

 or the Tungus. Much information of scien- 

 tific interest has been acquired, and a large 

 collection of costumes, weapons, implements, 

 and ornaments made of copper and iron has 

 been made. These will, it is hoped, be ex- 

 hibited later in Europe and America. 



The mid-year review of the copper situation 

 by B. S. Butler, of the United States Geolog- 

 ical Survey, records a general betterment in 

 the six months' period. At the beginning of 

 the year 1915 most of the large copper pro- 

 ducing companies of the United States had 

 for nearly five months been operating on a 

 50 to 60 per cent, basis and probably none were 

 producing at normal capacity. A considerable 

 proportion of the smaller producers had shut 

 down their plants, where this could be done 

 without great loss. Developments and im- 

 provements had been generally suspended. 

 Copper was selling below 13 cents a pound 

 and had been considerably lower. Wages had 

 been reduced in most of the camps and many 

 men had been either laid off or were employed 

 only part time. Soon after the first of the 

 year, however, there was a notable improve- 

 ment in the demand for copper and the price
