Mr. Bonney is disi>osedto question Mr. Teall'sstatement that this serpentine is 



an altered hornblende rock, but regards it rather as derived from a rock in which 



olivine was an essential constituent.

Describes from the Tyrolian Alps a series of six rocks, comprising: (1) Staurolite 

 mica schists, (2) garnet amphibolites, (3) pyroxenic serpentines, (4) tourmaline 

 granite, (5) porphyrites, and (6) pitchstone pori)hyry. The garnet amphibolite 

 is interesting mainly from its pseudomorphs of plagioclases after garnets. The 

 serpentines are derived from diallage, brouzite or enstatite, and are appropriately 

 named pyroxene serpentine. The porphyrites are classed as hornblende, uralite, 

 mica, and garnet porphyrites ; the last are characterized by the occurrence of 

 numerous reddish brown garnets, the largest of the dimensions of a hemp-seed, 

 and with channeled and rounded faces shown to be due to oscillatory combina- 

 tions of dodecahedral with icositetrahedral forms. The pitchstone pori)hyry 

 presents a micro-crystalline or micro-felsitic ground-mass with fluidal struct, 

 lire with orthoclase and oligoclase porphyritically developed and more rarely 

 quartz aud biotite. It occurs in the form of independent dikes and stocks, 

 oftenof considerable size, cutting the prevailing (luartz-porphyry and present- 

 ing sharply defined borders without transitions between the two anywhere dis- 

 cernable.
