At Montmartre, near Paris, it is in compact nodules, with 
small needle-like crystals. 
In the eastern part of France it is obtained in blue fibrous 
masses in the lower chalk, or “‘ Neocomien.” 
In Germany, at Dornberg, near Jena, where there is a blue 
fibrous variety found in layers; and tabular crystals fill up the 
crevices of the rock. At Jena we have a blue variety of 
Celestite, which is pleochroic, occurring in marly limestone. 
In Wurtemburg it pervades the Ammonite Beds. 
At Weser, in the Oolitic formation, it fills the interior of 
fossil bivalves. Near Ratisbon, at Pschow, on the Danube, the 
erystals in the limestone are of rich tabular combinations. At 
Scharfenberg, near Meissen, it is yielded in the red marls. 
In Hungary, near Herrengrund, in small blue crystals in 
limestone. Celestite occurs also in the Tyrolese Alps. 
In Italy, at Montecchio Maggiore, in amygdaloid rock; and 
in Sicily in the sulphur marls in bands and courses, named 
“ Strontian Zones.” The crystals are beautifully white, when 
not pellucid, with sulphur and gypsum. The Girgenti Valley, 
at Caltanissetta, at Lercara, at Catollica. Also in the Valleys 
of Noto and Mazzaro. Asa matter of caution we observe that 
no heed is to be given to the word Girgenti, for as in the case of 
shells, the dealers are ready, when asked, to proffer the word 
Singapore, when they do not know whence the shell came from, 
so the Sicilian gives the name Girgenti to every specimen of 
Celestite. 
In Switzerland at Bex, and in Spain at Conil, fine crystals 
are produced. In the Seisser Alps it is in lamellar or in 
radiated nodules. 
In North America and Canada: at Kington and at Stron- 
tian Island, Lake Hrie, large well-formed but complicated 
crystals. Dana gives the names of several other places in the 
United States, and in the Dominion, where the mineral is 
obtained. 
In Africa, among others, may be mentioned Mokattam, 
near Cairo: it occurs in the nummulitic limestones in large 
crystals, and in groups inclosing nummulites, and other
