9h. 36m. 50s. of my chronometer. The observations were as
follows:—

Chron. 2. 24. 40. ©'s Altitude, 21° 55'

2. 26. 20. „ Azimuth, N. 84° 20' XV.

2. 29 35. „ Altitude, 20° 59'

2. 31. 44. „ Azimuth, N. 83° 40' W.

2. 32. 15. „ Altitude, 20° 30'

These observations, worked out, in 1839, by Commander H. G.
Hamilton, R.N., gave the following result: variation, 8° 3' 15" W.

Analysis of salt ivater from the lake of Kodj Hissar.

I am indebted to Mr. Phillips, of the Museum of Economic
Geology, for the following account of the water from the, salt lake of
Kodj Hissar, which I brought from the spot. Mr. Phillips says,
" I find its specific gravity to be nearly 1.2398, but as a few crystals
of common salt had separated either by cold or evaporation, its sp. gr.
may be considered as equal to 1.24.

" It contains 32.2 per cent of saline matter, consisting chiefly of
common salt, but mixed with a considerable quantity of sulphate of
magnesia and chloride of magnesium, with a little sulphate of lime,
and a trace of bromine, but no iodine."

The great peculiarities therefore appear to be its high specific
gravity, and the great amount of saline matter. The specific gravity
of the water of the Dead Sea, hitherto considered the heaviest, has
been stated by Dr. Marcet at 1.21, that of sea-water being 1.028.
The amount of saline matter contained in the water of the Dead Sea
is, according to the same authority, only 24.5.*
