to 20, in the year. This is at Bu-shahr, where alone it
has been approximately registered. On the Arab coast
it is probably less. With rare exceptions, it falls chiefly in the autumn and

fall very rarely (see Bushire, Revised Gazetteer of Persia, page 5S).

when the sails appear in the morning as if a heavy shower had fallen.
Fogs .— Dense fogs, wetting everything like rain, occur at times near the
coast, and always in the morning. They only last a few hours.
Barometer .—The range of the barometer is not great compared with
more northern latitudes, although greater than in the Indian Ocean.

29-70" and 30-80"; average about SOTO".
In summer there is a remarkable permanent depression of the mercurv.

nnd August stands, with little variation, at about 29-55", varying between
29-4 5" and 29'65". By the end of September it again stands at its average
at about 30 UO".
