for the present will be directed toward the 

 so-called Spruce Tree House, which he will 

 restore, before attempting the preservation of 

 the Cliff Palace. The Cliff Palace is npt only 

 the finest but also the largest example of 

 cliff house architecture in our southwest. In 

 the Cliff Palace, Dr. Fewkes plans to excavate 

 all the rooms and plazas to their floors, re- 

 move accumulated debris, repair the walls 

 that are in danger of falling, and put the 

 ruin in such a condition that a visitor may 

 walk through the courts and rooms without 

 obstruction. Dr. Pewkes has gone to the 

 Mesa Verde Park from the Casa Grande ruin, 

 Pinal County, Arizona, where he has been at 

 work during the winter season unearthing the 

 remains of an extensive prehistoric city. 



Professoe C. J. Chamberlain visited Mexico 

 during March and April to continue his 

 studies upon the Mexican cycads. Besides 

 securing abundant material and numerous 

 photographs of Dioon edule and D. spinu- 

 losum, he found at Santa Catarina in the 

 state of Oaxaca a new species of Dioon which 

 is clearly intermediate between the other two 

 species, having the habit of D. edule with the 

 spinulose leaf of D. spinulosum. The leaf is 

 not so spinulose, however, as in D. spinulosum. 

 Further observations were also made upon 

 Ceratozamia. 



Professor E. D. Campbell, director of the 

 chemical laboratories of the University of 

 Michigan, recently visited the University of 

 Wisconsin and delivered an address to the 

 faculty and students of the chemistry depart- 

 ment on " Technical Chemistry." Sigma Xi, 

 the honorary scientific society, entertained 

 Professor Campbell at a banquet at which he 

 gave a second address on " The Effect of Free 

 Magnesia on Cements." Through an accident 

 in 1891 Professor Campbell lost his sight ; but 

 in spite of the fact he has risen to his present 

 high position, doing considerable valuable 

 original research work, especially on the 

 chemistry of cement and iron. Many of his 

 pupils now occupy responsible positions in 

 university faculties, among them Professor E. 

 B. Hart, head of the department of agricul- 

 tural chemistry and Professor Richard 



Fischer, of the chemistry department of the 

 University of Wisconsin. 



An effort is being made to erect at Mont- 

 pellier, France, on the grounds of the National 

 School of Agriculture, a moniunent to the late 

 Gustave Foex, the French horticulturist whose 

 work on the grapevine Phylloxera and other 

 vitieultural questions is so well known to the 

 horticultural world. A considerable amount 

 of money has been raised in Europe, and the 

 committee hopes to obtain something in 

 America between the present date and the end 

 of next September. Americans desirous of 

 contributing any sum, large or small, may do 

 so by addressing the Comite d'Organisation, 

 Monument Gustave Foex, Montpellier, France, 

 or the American representative of the Com- 

 mittee, Dr. L. O. Howard, U. S. Department 

 of Agriculture, Washington, D. C. 



A STATUE of Liebig is to be erected in Darm- 

 stadt, where he was born in 1803. The cor- 

 poration of Darmstadt has contributed 3,000 

 Marks towards the expenses. 



Sib John Evans, K.C.B., F.E.S., the emi- 

 nent British archeologist, past president of 

 the British Association for the Advancement 

 of Science, died at his residence, Britwell, 

 Berkhampsted, on May 31, in his eighty-fifth 

 year. 



Dr. Oskab Langendorf, professor of phys- 

 iology at Eostock, has died at the age of 

 fifty-five years. 



The deaths are also announced of Dr. A. 

 Belohoubek, professor of pharmaceutical 

 chemistry in Prague, of Dr. Hermann Wedd- 

 ing, professor of mining at Berlin, and of 

 Dr. Ulrich Behn, decent for physics at Berlin. 



There will be a New York State civil 

 service examination for the chief of division

 for vice-director of the New York Library 

 School, at a salary which may be $2,500. The 

 latter position is open to both men and 

 women. Applications for these two positions 

 will be received until July 1, 1908. A special
