180 Miscellaneous Intelligence. 
7. Llodine in Mineral Waters, &c.—At p. 168 of the last volume 
of the Journal, was noticed the presence of iodine in the waters of 
Sales in Piedmont. It was discovered in them by M. Angelina. 
It appears that since then M. Kriiger of Rostock, has found iodine 
in the mother liquor of the saline springs of Siilzer in Mecklen- 
burgh-Schwerin, and M. Fuschs has found the same substance in 
the mother water of the Sal Gem of Hall in the Tyrol. It ap- 
pears, however, that as yet the iodine has not really been sepa- 
rated from their mother liquors, but its presence has been ascer- 
tained by the blue colour given to starch dissolved in nitric acid, 
and. there appears to be no doubts in the minds of the experiment- 
_ ers on the reality ofits presence.—Gvor. de Fisica. ' 
8. New Vesuvian Minerals—MM. Monticelli and Covelli 
mention the following minerals as having been sent forth to the sur- 
face of the earth during the eruption of Vesuvius in October, 
1822. 1, Two small pieces of true lapis lazula found in the 
red sand sent forth on the 24th of October. 2. Several 
varieties of quartz, resinous quartz, and its passages into a lava 
composed of amphigene and pyroxene. 3. White and green 
phosphate of lime in fine hexaédral prisms and acicular crystals. 
4, Perfect cubes of melilite, much larger than. those of Capo di 
Bove. The two latter species were found in a current on the 
sides of Monte Somma above Pollena. 5. Gehlenite resembling 
that of Tassa. 6. Specula iron in brilliant plates above an inch 
wide. 7. Oxide of iron in octoédrons, above half an inch in dia- 
meter; the same also in mammelated or fused masses. 8. Anti- 
monial iron. 9. Glass of antimony apparently containing a small 
quantity of osmium.—Bvb. Univ. xxy. 42. 
9, Products of Combustion of certain Coal Strata.—In the neigh- 
bourhood of Aubin (Aveyron,) there exist certain coal strata, some 
of which are worked, and others are burning, having been on fire 
for thirty or forty years. It has been remarked as singular that no 
muriatic acid or ammonia occur in the products of this combustion : 
much sulphurous acid escapes, and various portions of sublimed 
sulphur, and acid aluminous efflorescences have been collected ; 
but on chemically examining these and the other products ob- 
tained, neither muriatic acid nor ammonia have been observed. 
The coal nevertheless contains abundance of azote, and on distilla- 
tion affords carbonate of ammonia. 
10. Advancement of the Ground.—The inhabitants of the vil- 
lage of Hayotte, in the parish of Champlain, Canada, were alarmed 
on the 28th of August, 1823, by the motion of a large tract of 
Jand, containing a superficies of 207. arpents, It moved five or 
six arpents, (about three hundred and sixty yards) from the water’s
