PLIOCENE FORMATION OF SOUTHERN OREGON. 491 



Note. — We have also received a letter from a member of the Wisconsin 

 Academy of Sciences living at Racine, informing us that Mr. Conant has, some- 

 time since, admitted that he was mistaken in making the statement quoted by 

 Prof. Reid relating to the finding of molds for copper implements in Wisconsin.
