I. Of certain truths founded on reason and experience ; and of hurricanes 

 (Tufdn, rv<pa>v ), 



Be it known that the science of navigation is founded on reason 

 and experience ; every thing which agrees with both is certain ; if you 

 ask which certitude is greater, that of reason or that of experience, 

 we answer that this is sometimes the case with reason and some- 

 times with experience ; the dair 1 that is to say the courses 2 and 

 monsoons are more known by experience ; but the knowledge of the 

 celestial signs, the arithmetic rules, the ighzdr 3 , and irqdq*, that is to 

 say, the knowledge whether you must keep the sea or steer towards the 

 land, and what belongs to it, is all dependent on reasoning ; again 

 the measures and distances are all founded on experience and on reason 

 conjointly ; but the calculated courses 5 , or rather the regulated tracks

* We have endeavoured as before to meet the illustrious translator's object 

 in favoring us with the continuation of this curious work, by tracing out the 

 places alluded to, and affording such other illustrations as our position in India 

 permits. A copy of the last edition of Horsburgh containing the lateat labors 

 of our Indian marine surveyors, for which we are indebted to Mr. Greenlaw 

 has been of much use. Most of the native names on the coasts of Arabia, &c. 

 Me carefully noted by the Bombay officers.— Ed.
