12 GEOLOGICAL MEMOIRS. 
peninsula of Lomin, from M. Okladnikow, a citizen of Mesen, that 
in the year 1839 he found near Lake Lohaloto, 50 versts from the 
mouth of the Yarumbe, on the Obi penimsula, a mammoth skeleton 
in an upright position. 
The thick coat of mud that evidently enclosed the bodies of the 
Wilui rhinoceros and Adams’s mammoth was probably sufficient to 
protect them completely from the mfiuence of the atmosphere, and 
consequently from putrefaction, until they were subsequently frozen 
and thus preserved for thousands of years as a puzzle to naturalists. 
It is thus not necessary to imagine a sudden, inexplicable, irruption 
of a glacial epoch, and a no less inexplicable instantaneous cooling 
down of the northern hemisphere, in order to explain the occurrence 
of the carcases of these pachyderms, which were probably killed by 
asphyxia (drowned). In consequence of the former higher tempera- 
ture of the globe, Siberia, when it was the abode of these pachy- 
derms, may indeed have been warmer than at present ; but the frag- 
ments of food from the teeth of the rhinoceros above-mentioned do 
not indicate the vegetation of a warm region.

On the Rockx-Satt Deposit at StTassFuRTH, and on the occur- 
rence of BoRACITE as a Mountain Rock in that Formation. By 
M. Karsten. 
[From the Berlin Monatsbericht for 1847, p. 14.] 
Tue richness of the salt springs at Stassfurth, which contain 17:16 
per cent. of saline matter, and the character of the rocks m the vici- 
nity, left no doubt that the salt deposit by which they are fed existed 
at no great distance. ‘The principal well is 1714 feet deep, of which 
344 feet are in the alluvial soil and the detritus accumulated by the 
Bode, the spring lying close to the right bank of this river. The 
remaining 137 feet pass through soft, clayey, red-coloured beds of 
sandstone, belonging to the variegated sandstone formation (Bunter 
Sandstem). About 170 feet from this well a bore was commenced in 
1839, in search of the salt deposit. The opening of the bore is 
221 feet above the sea, and the following beds were passed through 
in descending order: 26 feet alluvium, 556 feet 2 inches variegated 
sandstone, 67 feet 54 inches gypsum, 147 feet 95 inches anhydrite, 
in which the first traces of rock-salt appeared at the depth of 790 
and 794 feet. A deposit 28 feet 103 inches thick followed, apparently 
consisting of bluish grey marl, white and red coloured gypsum and 
grey limestone, alternating in rapid succession, but without any de- 
finite order. This bed apparently belongs to the rock-salt forma- 
tion, though this mineral did not appear in the fragments bronzht 
up by the borer, having probably been dissolved in the water. The 
bed of rock-salt was reached at a depth of 826 feet 34 inches, or 
6052 feet below the sea-level, and the boring has been continued i in 
it ie 154 feet 54 inches; so that in December 1846 the bore had a 
total depth of 980 feet 9 inches.
