We must recollect in considering this, and all the other results 

 which this Memoir offers, that we are very far from possessing all the 

 data for the period of time over which it extends ; as, up to the opening 

 of the trade with China and the establishment of opium-clippers from 

 Calcutta and Bombay to that country, the China Sea was in certain 

 months rarely navigated by English ships, and of those few (Indian 

 country ships, Americans and others,) which did navigate at those times, 

 we have not a single record ; all this should be duly borne in mind, and 

 that the most we can expect are approximate results only from imperfect 

 data. Another consideration also should not be overlooked, which is, 

 that the tracks of the storms seem to be influenced by the quarter 

 in which they arise, and that a ship off the Coast of Luconia, or in 

 the S. E. part of the China Sea, in the angle formed by the Philippines 

 and Palawan, may have more chances of a storm coming up from the 

 Southward of East, than one between the Macclesfield Shoal and 

 the Grand Ladrone. This consideration also should not be forgotten. 

 In my introductory notice I have remarked, that when we cannot 

 prove the theory wholly by the evidence deduced from one storm, we 

 may prove it in parts by the careful analysis of separate storms. I
