Some little time ago I had the pleasure of seeing, through the 

 kind offices of Mr. F. E. Chapman, some very remarkable 

 traces of the moa, and I propose to offer to the society a 

 short description of these interesting relics. 



Mr. Chapman, in a paper communicated to this society in

 by him in that year ; and, as he had also noticed somewhat

 which have been considerably reduced in area by drains cut 

 in various directions. The altitude is about 2,000ft., and the
