Productioni of Wier''s Cave* 59 



below, a river of the same acid. (See Tillocii's Phil. Mag. 

 Vol. XLII. p. 182.) It is a most curious phenomenon, and we 

 believe entirely without a parallel. Another river, called the 

 White River, unites with this some miles below its origin : this 

 river, which is so called from the turbidness of its waters, is 

 salutary to men and animals ; fishes live in it, and vegetation is 

 nourished by its waters ; but after the junction it becomes clear ; 

 the acid dissolving the earthy particles which ,discoloured it, 

 and it now becomes fatal to living beings : kills the fish, destroys 

 the vegetation, and corrodes the stones in its channel. This 

 remarkable river flows from Mount Idienne, in the province of 

 BagniaVangni, in the eastern part of Java. 



Art. IX. Productions of Wier^s Cave, in Virginia. 



W, 



E are indebted to the Reverend Elias Cornelius, and to 

 Mr. John H. Kain, for a collection of the calcareous incrusta- 

 tions of Wier's Cave, in Virginia. 



The stalactites, and stalagmites, and various incrustations, 

 are of uncommon size and beauty. Some of the stalactites 

 have a delicate whiteness, and a brilliancy arising from their 

 crystallized structure, which, with the regularity of their forms, 

 give them a fair title to rank with those of the famous caverns 

 in the Peak of Derbyshire, in the island of Antiparos, &c. 



In these stalactites, the structure is most remarkably distinct, 

 both in the fibrous and concentric lamellar form. In this col- 

 lection were observed many forms of the crystallized hard car- 

 bonates of lime, of Count Bournon. 



For a description of the cavern from which these speci- 

 mens came, we. refer to the succeeding memoir, by Mr. Kain
