volume, has recently been issued under date of December 15, 

 1903. It contains thirty-two pages and gives seventy-nine 

 abstracts, of physical and chemical papers, in German, French or 

 English, according to their original source. It is much to be 

 hoped that this new review may meet with the general coopera- 

 tion and support which it deserves. 



4. A Description of the Brains and Spinal Cords of Two 

 Brothers dead of Hereditary Ataxia • by Lewellys F. Barker. 

 The Decennial Publications of the University of Chicago, First 

 Series, Vol. X, 38 pp., 4to, with twelve plates. Chicago, 1903. 

 (The University of Chicago Press.) — This memoir gives the results 

 of an examination, in part microscopic, of the brains and spinal 

 cords of two brothers, who died of hereditary ataxia. These 

 were cases XVIII and XX of the Series in the family described 

 by Dr. Sanger Brown, who gives here a clinical introduction. 

 Twelve plates with forty-six figures follow the text. 



5. Field Columbian Museum. — Publications 79, 80 of the 

 Zoological Series, Vol. Ill, Nos. 12, 13, have recently been 

 issued. The former, pp. 199-232, contains a list of mammals 

 collected by Edmund Heller in Lower California, with descrip- 

 tions of apparently new species. The latter, pp. 233-237, gives 

 descriptions of apparently new species of Heteromys and Ursus 

 from Washington and Mexico. Both papers are by D. G. Elliot. 



6. The Planetary System ; by F. B. Taylor. 268 pp. Pub- 

 lished by the author, Fort Wayne, Indiana. — If Newton's solu- 

 tion of the problem of three bodies were correct it ought to yield 

 a general law for the stability of inner satellites. His analysis, 

 however, shows only indeterminate stability. The theory pre- 

 sented by Mr. Taylor is claimed to yield a law of determined 

 stability of satellites and hence a logical theory for the structure 

 and growth of the solar system. 



7. Metallic Ornaments of the New York Indians / by W. M. 

 Beauchamp. Pp.120. Albany, 1903. (New York State Museum, 

 F. J. H. Merrill, Director : Bulletin 73, Archaeology 8 ; Bulletin 

 305 of the University of the State of New York.) — The number 

 and diversity of Indian ornaments here described will surprise 

 and interest the reader not previously informed on the subject. 

 Upwards of four hundred figures on thirty-seven plates are 

 required for adequate illustration. 



8. Queries in Ethnography ; by A. G. Keller. 70 pp. 

 (Longmans, Green & Co.) — Professor Keller has prepared an 

 admirable list of queries by use of which observations of travelers 

 and missionaries may be made with such accuracy and perti- 

 nency as to be of definite scientific value.
