He had also completed some further examinations of the wave of the first order, and 

 could now present the subject in a tolerably complete form. 



Observations on Oceanic Waves. By William Walker. 



After detailing the advantages which the locality where these observations were 

 made (Bovisand, near Plymouth) possessed for such an object, such as complete ex- 

 posure to the waves of the Atlantic, a series of buoys at ascertained distances, well- 

 observed soundings, a tide gauge fixed at the pier, and elevated cliffs from which the 

 waves in series may be conveniently observed, the author described his methods of 

 observing, and presented in a tabular form the results of his observations made durin°-

From these data it does not appear that the ratios between the heights, velocities, and 



other elements of waves, are regulated by any constant law. On the 28th of September 



the waves were found to travel at the rate of 46 feet per second, being 460 feet apart, 



nd breaking in five fathoms water; the next day their velocity was only 42 feet per
