Correction. Substitute the following for the second paragraph 

 under the meeting of May 19, 1886, page 324. 



Mr. F. W. Putnam described the methods of manufacture of 

 stone implements by primitive man, and showed a collection of 

 celts and other objects of jade and jadite from New Zealand, the 

 Swiss Lake dwellings and Central America. He also showed va- 

 rious ornaments from Central America, which had been made b}^ 

 cutting up celts. As these Central American jadite objects are of 

 the same varieties of the stone found in place in Asia, and as these 

 varieties are not yet known from America, he thought these spec- 

 imens might indicate that their original owners brought them in 

 early times from Asia.
