late Professor of Mineralogy at Frieberg. 185 
of the Mines, he hada great share in the direction both of the 
Mineralogical Academy and of the administration in general. 
Two things must be mentioned here with particular honour—the 
works begun in 1786, to furnish a great part of the deeper mines 
with water, in order to get water for driving the wheels. This 
astonishing aqueduct, particularly the artificial canal of Doer- 
renthal, with its subterraneous bricked channels, already extend- 
ing above aleague, are in the main due to him, though Scheuch- 
Jer made the plan, and Lampe the calculations. By the:con- 
tinued support of the ever active king of Saxony, this great work 
still proceeds in the most prosperous manner. The Amalgama- 
tion works, twice built by the excellent Charpentier, chief of the 
Council of the Mines, (the first building was maliciously burnt 
down,) and for ever secured by most ingenious fire-engines from 
similar accidents, are indeed unique:—a miracle to all who be- 
hold them, and a jewel in the crown of the Saxon art of mining, 
and of the unostentatious energy with which the sovereign of 
Saxony caused the most expensive undertakings to be executed 
in silence. Less known and visited by foreigners, though on it 
depends the continuation of the mining in Saxony, is this un- 
dertaking of canals and aqueducts, which has already cost above 
half a million of crowns, and on which more than a thousand 
men are employed. ‘The mineralogical survey and description 
of all Saxony, divided into districts, which has been prosecuted 
for these twenty years, under scholars of Werner, and includes 
the forest of Thuringen, and even a part of the Harz, uniting 
too with the mountains on the frontiers of Bohemia and Silesia, 
will one day give our country a mineralogical map, which for 
exactness and extent surpasses what any other country can pro- 
duce. This too was Werner’s work, and was constantly directed 
by him in the most attentive manner. In his visits to Prague 
aud Vienna, he found means to interest the Austrian government 
in these mineralogical surveys ; and it is to be hoped that the en- 
tightened Bavarian government, as well as the direction of the 
nines in the Prussian monarchy under Werner’s grateful scholars 
in Berlin and Silesia, will readily eontribute to support and com- 
plete the great work which Werner so happily set on foot. In 
England and Scotland excellent mincralogical maps of single 
counties have lately been published according to Werner’s ideas. 
His cabinet of minerals, unrivalled in completeness and scientific 
arrangement, and consisting of above 100,000 specimens, has 
become, in consideration ‘of a life annuity, the amount of which 
devolves to the Institution itself, the property of the Frieberg 
Mineratogical Academy. Werner's favourite pupil Koehler is 
appointed inspector of it. Werner had received from England 
an offer of 50,000 crowns for it, He sold it to his country for 
40,000,
