ral people to visit the summit of the hill after the storm was over; 
where they found the strongly matted turf, where the spout 
poured out its waters, completely torn off, the subsoil washed 
away, and a considerable space laid bare to the rock, 
This I think must be considered as conclusive of the descent 
of the water in this- case, as the rise of the water in the other. 
I remain yours ever,

A new Variation Chart of the Navigable Globe, from 60 Degrees 
North to 60 Degrees South Latitude. By Tuomas YEATES. 
Tue charts hitherto published being only transcripts of Dr. 
Halley’s original chart, with few corrections for the change of 
variation since his time, and none of them extending heyond the 
Atlantic and Indian oceans; navigators have long regretted the 
want of an accurate variation chart comprehending the whole 
circuit of the navigable ocean and seas of our globe. To sup- 
ply this want, the author of the present chart has. with much- 
labour and care constructed a general chart of the variation of. 
the magnetic needle, for all the known seas within sixty degrees 
of the equator, north and south, from accurate documents ob- 
tained from Spanish surveys in the Pacific Ocean, journals at the 
Hydrographical Office, Admiralty, and the East India House, 
collated with tables of the variation recently formed from the 
observations of different navigators. ; 
The Chart is on the Mercator’s projection, drawn with the 
latest improvements, and the magnetic lines are drawn upon it 
throughout for every degree of change in the variation; with an’ 
eccurate delineation of the magnetic equator and meridians, 
never before introduced in charts of this description, and the 
whole is accompanied with suitable remarks and illustrations. 
The Chart is presumed to form a valuable accompaniment to’ 
all navigation charts in present use, and will be found not only 
jmportant to the navigator, but interesting to the philosopher. 
and the man of science, in exploring the theory and properties » 
of the magnetical instruments used on sea and land.
