1, 2. 

 Study of the fossil plants from 

 two classic localities in Bolivia — 

 the copper district of Corocoro 

 and the silver and tin district 

 of Potosi. The rather definite 

 results regarding the age of 

 these deposits is thought to 

 have not only an important bear- 

 ing on the time of mineraliza- 

 tion in these regions, but to be 

 of the greatest value in indicat- 

 ing the period of elevation of 

 the Andes, which is shown to 

 be much later and more pro- 

 found than hitherto supposed. 

 A discussion of the results of 

 this study is followed by a de- 

 scription of the flora, and by an 

 account of a new species of 

 brachiopod by Prof. Charles 

 Schuehert.
