Fig. a. 



(Sp. No. 23319. Without analyzer, x 35.) 



Moderately fine grained bornblende-gabbro. The constituents hornblende, plagioolase, and iron 

 oxide can be readily recognized. Many of the hornblende individuals contain a great number of 

 minute inclusions. (Described, p. 240.) 



Pig. B. 



(Sp. No. 2375.5. Without analyzer, x 35.) 



Brouzite-noiite. The rock cousists of bronzite, hornblende, and plagioclase. The bronzite 

 individuals show a tinge of green aud pink, and are slightly fibrous, due to beginning alteration. 

 Cracks, filled with alteration products, cross them. The bronzite is frequently surrounded by a rim 

 of brown hornblende. In some parts of the rock it is partly automorphic. The hornblende can be 

 readily recognized by its strong yellowish and reddish-brown color. It is in anhedra. The plagioclase 

 is the white mineral including numerous minute dark specks. It, like the bronzite, is xenomorphio.
