NATURAL HISTORY OF GLUCINE.

For the discovery of this earth we are indebted to Vauquelinwho found it in 1795, in the Aigue-marine or beryl, a transpa-rent stone of a green colour, and in the Emerald of Peru. Itexists combined with silex, argil, lime, and oxid of iron in theone; and with the same earths, with oxid of chrome, in the other.It has lately been discovered in the Gadolinite by Mr. Ekeberg.*Its name is taken from the Greek word (yXvxvg) which sig-nifies sweet or saccharine, because it gives that taste to the saltsit forms.
