An ADnotated 



List of Experiments in Physics 



By JAMES EDMUND IVES 



Associate Professor of Physics in the University 

 of Cincinnati 



Just Published ... 50 cents 



The most comprehensive list of physics 

 experiments available. 

 An annotated list of some three hundred experi- 

 ments in physics suitable for college students. In 

 most cases no attempt has been made to describe the 

 experiment, but a reference has been given to its full 

 description in a standard textbook. 



From the experiments given, lists can be made up 

 that mil be suitable for any particular class of 

 students, freshman, sophomore, academic or engineer, 

 ing students, or for the apparatus in any particular 

 laboratory.

Waves of the Sea and other 



Water Waves 



^1 



By VAUGHAN CORNISH, | 



Doctor of Science, Manobester University « 



Fifty illustrations'from photographs taken by the author. Cloth, pp. 375. Price, $2. 50 net.^ 



A critical examination of observations and measurements of waves and tbe discovery of the mode of their 

 production. The facts here set down in a very interesting manner are tbe results of fifteen years' study of 

 wave action in lakes and rivers as well as upon the ocean at different latitudes. ;. 



A few of the topics ably presented are : — 



SIZE and SPEED of DEEP SEA WAVES ; the numerical relation between length of fetch of wind and> 

 height of storm waves ; the wave length of the swell which reaches shores after storms : the give anct 

 take between air and water in tbe development of waves ; the effect of squalls and gusts upon waves. ^ 



On the Action of sea. <ma.ves to transport shingle, sand and mud. The building up of beaches — the undertow.;^ 



Stationary and progressive maves in rivers, flood waves, tidal bores, cross-stream progressive waves, sounds 

 of running water, tbe gushing 

 motion of cataracts, whirls and 

 eddies, conical structures pro- 

 duced by the breaking up of a 

 waterfall, the wave track of a 

 ship. 



This book offers an attractive 

 introduction to physiography and 

 the study of more difficult wave 

 phenomena in earthquakes, atmo- 

 spheric disturbances, as well as 

 wave action in relation to engi- 

 neering structures.
