but was shown to consist of a mixture of Nickel, Cobalt, 
Arsenic and Iron. (Gilb. Ann., XIX. 377.) 
ANDRONIA, an earth which existed only in the imagination 
of J. J. Winterl, of Pesth. He prepared it by igniting char- 
coal with saltpeter and exhausting with water, the residue 
consisting of Andronia. His statements excited much contro- 
versy; a committee of the French Academy of Sciences 
appointed to examine it, proved that it was but a mixture of 
Lime, Alumina, Iron Oxide and Silica, which materials it was 
suggested, came from the earthen crucibles in which Winterl 
conducted the experiments. (Gehlens J. und Gilberts 
Annalen.) 
THELIKE, discovered by Winterl. 
Nirricum, is the imaginary body, which according to 
Berzelius, united to Oxygen formed Nitrogen. 
ARAEON, is in accordance with Meissner’s views, ponderable 
caloric ; thus Hydrochloric acid is composed of two equiva- 
lents of Oxygen and one of water, combined with ARAEON 
and the imaginary radical Murtum. (Handworterbuch.) 
JUNONIUM, discovered by Thomson, in 1811, but its identi- 
ty with Cerium was soon proved by Wollaston. (Phil. Mag., 
XXXVI. 278, also Gilb. Ann., XLIV. 113.) | 
THoriuM; the first element known by this name, proved 
to be Phosphate of Yttria. (Schweigg., XXI. 15; Pogs. Ann., 
TV. 145.) 
VESTIUM, discovered in 1818, by von Vest. Faraday 
showed that it consisted of a mixture of Iron, Nickel, Sulphur 
and Arsenic. (Gilb. Ann., LIX. and LXIL) 
Wopanium, extracted from the so- -called Wodankies by 
Lampadius, 1818, but shown. by Stromeyer to consist of 
Nickel, Arsenic, &e. The mineralis now known as Gersdorffite. 
(Gilb, Ann., LX. and LXIV.) 
Croponium, discovered by Trommsdorff in 1820, was 
found in an incrustation, on a carboy of Sulphuric acid 
imported from England. Its name is derived from Crodo, an 
idol held in-veneration by the ancient people of Thuringia. 
Trommsdorff afterwards showed that it was but Lime and
