Saul Epsteen and Heman Burr Leonard: 

 •' On the Definition of Reducible Hypercomplex 

 Number Systems.' 



Peter Field: ' Quintic Curves for which P=: 1.' 



C. L. E. Moore: 'Classification of the Surfaces 

 of Singularities of the Quadratic Spherical Com- 

 plex.' 



Leonard Eugene Dickson : ' Subgroups of Order 

 a Power of p in the General and Special ??i-ary 

 Linear Homogeneous Groups in the GFlpn]. 



The introductory article in the May num- 

 ber of the American Geologist is a ' Biograph- 

 ical Sketch,' with portrait, of Benjamin West 

 Frazer by Persifor Frazer. This is followed 

 by Professor N. H. Winchell's article entitled 

 ' Deep Wells as a Source of Water Supply for 

 Minneapolis.' This paper, which is accom- 

 panied by several plates, is a presentation of 

 the ever-interesting problem of the water sup- 

 ply of cities. Miss Owen discusses the ' Evi- 

 dence on the Deposition of Loess.' R. R. 

 Rowley contributes a paper on ' Missouri 

 Paleontology,' which is illustrated by one 

 plate of figures and three new species are de- 

 scribed. The concluding article is by Pro- 

 fessor Warren Ilpham on ' Fjords and Hang- 

 ing Valleys.' 



The Museums Journal of Great Britain for 

 May notes that the principal subject for dis- 

 cussion at the coming meeting of the Mu- 

 seums' Association will be ' The Relation of 

 Provincial Museums to National Institutions,' 

 a topic to which American members can con- 

 tribute little, as here there are no relations, 

 save those of good feeling, each museum being 

 independent of others. Under the head of 

 ' A Notable Gift ' is recorded the presentation 

 to the British Museum of the reproduction of 

 the skeleton of Diplodocus carnegiei, in the 

 museum at Pittsburgh. Under ' Museum 

 Thefts ' is noticed the stealing of some Nelson 

 relics from the Liverpool Museum, primarily 

 due to the fact that a case was left unlocked 

 for some months. Apparently English mu- 

 seums do not suffer from the petty thefts of 

 ' relic seekers ' who, in our own museums, take 

 articles of little intrinsic but considerable 

 scientific value, thus doing very considerable 

 damage. 



The American Museum Journal for April 

 is called the Brontosaurus number, its prin- 

 cipal topic being ' The Mounted Skeleton of 

 Brontosaurus ' recently placed on exhibition. 

 Dr. Matthew tells how this skeleton was ob- 

 tained, transported and mounted, and dis- 

 cusses the habits and habitat of this enormous 

 brute as indicated by the bones. The two 

 new bird groups, the flamingos and the bird 

 life of the San Joaquin valley are also de- 

 scribed and illustrated by full-page plates.

HOGIETIES AND ACADEMIES. 



THE OREGON STATE ACADEMY OF SCIENCES. 



The need of some general scientific organ- 

 ization has for a number of years been keenly 

 felt by a number of teachers of science and
