 upon the older bone-beds containing the remains of extinct mam- 

 mals and man, are in the position which they occupied at the close 

 of the Glacial conditions, or have subsequently fallen into their 

 present site," is answered by stating that the new facts "go to

2. Air and its Relations to Life; by Walter Noel Hahti.et, 

 F.C.S., Kings College, London. "263 pp. 12mo. New York, 1875. 

 (D. Appleton & Co.)— This very readable little volume contains 

 the substance of a course of six summer lectures delivered in 1874 

 at the Royal Institute of Great Britain. The author exhibits 

 the rare faculty of presenting the results of exact scienoe in a lorm 

 perfectly intelligible and attractive to intelligent people not famil- 

 iar with the technical language of science. The researches of the 

 most trustworthy investigators are cited with good judgment from 

 the days of Black and Lavoisier to those of Retenkofer, Angus 

 Smith and Pasteur. Indeed it is not easy to say where else in 

 English we can find so full a statement of the researches of 

 Pasteur as in chapter four of Mr, Hartley's essay.
