1 Since this paper was put in type Mr. Stuart Weller has definitely correlated 

 the Batesville sandstone of these tables with the Aux Vases sandstone of Illinois. 

 His results show that the hitherto tentative correlations of these Arkansas and 

 Indian Territory rocks require more careful paleontologic study. — Trans N. Y.
