Fig. 7. — T'op view of Mica- schist, showing flattened Garnets. 



To assist in indicating the appearance of the garnets two drawings * 

 (PL XV.) were made from the slide (Rock-section no. 3), and the 

 author has also made a chemical analysis of one of the garnets.

Silica 49-50 



Iron-protoxide 36-25 



Alumina 6-25 



Lime 1-43 



Magnesia 1-44 



Manganese 1*76 



Hygroscopic water 0*37 



Combined water 3-20

From the above analysis, as well as from the microscopic exami- 

 nation, it is an iron-alumina garnet, probably in its original state 



* The author is indebted to Mr. Felix Oswald for making the above 

 drawings.
