368 M. Stromeyer’s Analyses. 
2. M. Strromerer, a distinguished professor of Chemist- 
ty at Gottingen, published about a year ago, the first vol- 
ume of a work in which he intends to communicate in due 
order the result of his researches. As the well known 
ability and accuracy of M. Stromeyer, gives a high value to 
his labours, we doubt not that it will afford satisfaction to 
our mineralogical readers, if we state the analyses of the 
principal substances which he has examined. 
1, Arragonite—It will be recollected that M. Stromey- 
er was the first who discovered the presence of Strontian in 
this mineral, and thereby explained the singular anomaly 
which it presented, considered as pure Carbonate of Lime. 
Prismatic Arrogonite from Molina in Arragon, contains, 
Carbonate of Lime 95.68, Carb. of Strontian 4.02, Wa- 
ter of Crystallization 0.30=100. Nine of the Scapiform 
varieties contain of Carb. of Lime, from 95.30 to $9.13, 
Carb. of Strontian 0.72 to 4.10, Water 0.15 to 0.60. 
Two of the fibrous varieties, (both from Bohemia,) Carb. 
of Lime 98.76 and 99.29, Carb. of Strontian 1.02 an 
0.51, Water 0.22 and 0.20, 
2. Magnesite, hard, from Baumgarten in Silesia, Mag- 
nesia 47.63, Oxide of Manganese 0.21, Carbonic Acid 
50.75, Water 1.41=100. 
3. Prcropharmacolite of Rugelsdorf in Hessia. This 
mineral resembles in many of its properties pharmacolite, 
(arseniate of lime,) but the magnesia which it contains 
renders it remarkably distinct.
