68 WAVES OF THE SEA 



formula gives 36.75 feet for 600 geographical 

 miles from the windward shore, which is in 

 fair agreement with Scoresby's observations on 

 March 5, 1848 (see ante, p. 42). 



Waves on the South Atlantic and Southern Indian 



Oceans 



Sailors agree that storm -waves are seen in their 

 fullest and most typical development in those 

 Southern latitudes where the ocean uninterruptedly 

 encircles the globe. They are observed from ships 

 which go round the Cape of Good Hope, and by 

 those which go round Cape Horn. I proceed to 

 the observations made by the late Lieutenant Paris, 1 

 of the French Navy, in 1867, when proceeding by 

 the corvette Dupleix to the China station via the 

 Cape of Good Hope. The Dupleix was a sailing 

 vessel with auxiliary steam. She ran before a 

 prolonged westerly gale during the last days of- 

 October, 1867, having passed the Agulhas Bank, 

 but being still west of the Island of St. Paul. The 

 vessel seems, therefore, to have been somewhere 

 between 40 and 8oE. Long, and about 40 S. Lat. 

 After this storm the vessel proceeded northwards 

 under steam through the calms of Capricorn,
