Rh is in lat. 28° 0' 1" north, and in long. 39° 16' 45" east of the meridian of Greenwich. Our weather there had few changes. The general wind was north-west, or more northerly. This blowing along the direction of the Gulf -brought a great deal of damp along with it; and this damp increases as the season advances. Once in twelve or fourteen days, perhaps, we had a south wind, which was always dry. The highest degree of the barometer at Jidda, on the 5th of June, wind north, was 26° 6', and the lowest on the 18th of same month, wind north-west, was 25° 7'. The highest degree of the thermometer was 97° on the 12th of July, wind north, the lowest was 78° wind north.
