MR. T. HEELIS ON OCEAN SWELL. 



279 



district in which the L^Agulhas current and its branches 

 flow against the prevailing winds, should present phe- 

 nomena differing from those experienced south of that 

 parallel,, where the current and prevailing winds flow in 

 the same direction ; and again, the phenomena presented 

 in the district passed over in the inshore or homeward 

 passage round Cape Horn would difibr from those pre- 

 sented further to the southward. 



The following observations have been made in ships on 

 board of which I have made passages, and whose log-books 

 I have had opportunities of consulting : — 



The observations made on board the ' Jason/ ' Thunder,' 

 and ' City of Pekin,^ were recorded by myself. I have 

 added in the column headed Remarks, the causes of the 

 swell experienced in all cases in which such causes were 

 ascertained at the ship.
