Tomboro* ; the haze, the dampness, the rain, and winds 
seem to have a corresponding similarity. 
On the 9th of February, at sunset, the western sky 
was still hazy. 
On the 3rd we were within 30 miles of St. Anthony ; 
on the 4th, about 30 from Brava, and 45 from Fogo. I 
attributed the phenomena to this latter island, the height 
of whose summit is 7000 feet above the sea, and from 
which smoke and ashes are almost always issuing, the 
latter in prodigious abundance; together with occasional 
streams of flowing brimstone and vast showers of stones, 
cast to a great height with a noise like that of thunder f 
About 20 degrees south of the line I boarded the 
barque Alhyn , from Greenock to Bombay. On ex¬ 
amining the log and charts, I found she had the same 
phenomena off the Cape de Verde group ; and that she 
crossed the equator the same day with us, but further to 
the west. 
In the Nautical Magazine! there is a notice of these 
phenomena experienced by Captain Hayward of the ship 
Garland . From the 9th to the 13th February, 1839, 
his sails were covered by the dust over an area extending 
from 10° to 2° 56' N., and from 29° 59' to 26° 30' W., 
being on the 9th 450, and on the 14th 850 miles distant 
from the nearest of the Cape de Verde islands. 
There is, thus, evidence that the dust fell in February, 
1839, for 11 days, and that it covered the ocean through¬ 
out 9° of longitude and 19° of latitude, having an area 
of nearly 500,000 miles. 
The circumstances are equally remarkable, whether 
proceeding from Fogo or from the desert; but the nature
