BY M. C. COOKE, M. A. 

 [Bead before this Society, Feb. 2, 1877.]

 unsatisfactory condition, requiring complete examination and veri- 

 fication. The present list must therefore be regarded as involving 

 no responsibility for accurate determination, but as a. preliminary 

 step towards securing verification:
