Sulphuric acid and lime united form gypsuvi . From that 
obtained at Montmatre in the vicinity of -the capital of 
France, the plaister of Paris used in commerce, is formed. 
Sulphate of lime is found in a state of great purity in On¬ 
ondaga*' and Madison counties, and on the borders of Ca¬ 
yuga lake. The quantities procured there are very great, 
and supply many parts of this and adjacent states. During 
the last year, it is calculated that 6000 tons have been sent 
into Pennsylvania from the vicinity of Cayuga lake.f It is 
also discovered in New-Jersey. Besides its very important 
use in agriculture, it is employed for the formation of stuc¬ 
co, and in modelling, if it be of uniform texture, and suffi¬ 
ciently delicate colour. Several beautiful specimens of fi¬ 
brous gypsum have been found at Onondaga. 
Fluate of lime or fluor spar has been noticed in New-Jer¬ 
sey, Connecticut, New-Hampshire,| and Virginia.§ Orna¬ 
mental vases of various colours are made from it in Derby¬ 
shire, (England) where a mine is found. The acid is used 
in etching on glass. 
Mr. Godon has observed the phosphate of lime in Penn- 
sylvania-li In the province of Estramadura, in Spain, it 
forms hills, and is used in building. 
Many other varieties of calcareous fossils have been no¬ 
ticed ; they are however unimportant in the arts. I cannot 
however leave this subject, without noticing the elastic mar¬ 
ble found in Massachusetts.^ Beautiful specimens of this 
uncommon mineral are in the possession of the mineralogi- 
cal committee.**

** I am informed by my friend Dr. Noyes, Prof, of Chemistry 
and Mineralogy at Hamilton College, that a substance resemb¬ 
ling chalk in all its properties, has recently been noticed in sev¬ 
eral towns in Oneida county. It has been used instead of lime 
in masonry.
