 No. 3 2 5 H 3 (12383) from the right bank of the Meshva river S..S.W. 

 of Bamanvada, appears in the hand-specimen as a white tremolite- 

 rock, exactly reproducing the pale green rock, £fe, in the criss- 

 cross and tufted arrangement of the fibres. There is, however, 

 a considerable amount of calcite in places, as also in parts of 3 2 , <, < r

 molite or actinolite.
