1776. THE PACIFIC OCEAN. 107 



liable to some error ; but I think I cannot be much 

 mistaken. Dr. Maskelyne, in his British Mariner's 

 Guide, places the Pic in the latitude of 28 12' 54". 

 This, with the bearing from the road, will give the 

 difference of longitude 43', which considerably ex- 

 ceeds the distance they reckon the Pic to be from 

 Santa Cruz. I made the latitude of the Pic to be 28 

 18' north. Upon that supposition, its longitude will 

 be as follows:

 But if the latitude of it is 28 12' 54", as in the 

 British Mariner's Guide, its longitude will be 13' 

 30" more westerly. 



The variation, when we were at anchor in the 

 road, by the mean of all our compasses, was found 

 to be 14 41' 20" west. The dip of the north end 

 of the needle was 61 52' 30". 



Some of Mr. Anderson's remarks on the natural 

 appearances of Teneriffe, and its productions ; and 

 what he observed himself, or learnt by information, 

 about the general state of the island, will be of use, 

 particularly in marking what changes may have 

 happened there since Mr. Glas visited it. They here 

 follow in his own words: 



" While we were standing in for the land, the 

 weather being perfectly clear, we had an opportunity 

 of seeing the celebrated Pic of Teneriffe. But, I 

 own, 1 was much disappointed in my expectation 

 with respect to its appearance. It is, certainly, far 

 from equalling the noble figure of Pico, one of the 

 western isles which 1 have seen ; though its perpen- 

 dicular height may be greater. This circumstance, 

 perhaps, arises from its being surrounded by other 

 very high hills ; whereas Pico stands without a rival. 

 " Behind the city of Santa Cruz, the country rises 

 gradually, and is of a moderate height. Beyond this,
