The cuftoras, which at Mocha are three per cent, upon In- 

 dia goods, are five here, when brought directly from India ; 

 but all goods whatever, brought from Jidda by merchants, 

 whether Turks or natives, pay feven per cent, at Loheia. 



Loheia is in lat. i5°4o' 52" north, and in long. 42 58-' 15" 

 eaft of the meridian of Greenwich. — The barometer, at its 

 higheft on the 7th day of Augud, was 26 9', and its lowed 

 26° 1', on the 30th of July. — The thermometer, when at its 

 higheft, was 99 on the 30th of the fame month, wind nonh- 

 ead ; and its lowed was 8 1° on the 9th of Augud, wind fouth 

 by ead. 



On the 3 id of Augud, at four o'clock in the morning, 

 I faw a comet for the fird time. The head of it was fcarce- 

 ly vifible in the telefcope, that is, its precife form, which 

 was a pale indidincl: luminous body, whofe edges were not 

 at all defined. Its tail extended full 20 . It feemed to be 

 a very thin vapour, for through it I didinguifhed feveral 

 dars of the fifth magnitude, which feemed to be increafed 

 in fize. The end of its tail had lod all its fiery colour, and 

 was very thin and white. I could didinguifh no nucleus, 

 nor any part that feemed redder or deeper than the red ; 

 for all was a dim-ill-defined fpot. At 4 hrs ' 1/ 24", on the 

 morning of the 3 id, it was didant 20 40.' from Rigel ; its 

 tail extended to three dars in Eridanus. 



The id of September Mahomet Gibberti arrived, bring- 

 ing with him the firman for the Naybe of Mafuah, and let- 

 ters from Metical Aga to *Ras Michael. He alfo brought 



a letter
