 study of the Spanish language. Between northern Mexico and the south- 

 ern extremity of the Andean System, is included one of the greatest earth- 

 quake provinces of the globe. The recent establishment by the Republic 

 of Chili of a well-equipped seismological service, and the initiation by 

 the Mexican government of an important serial publication largely devoted

 serial is issued by the Mexican Department of the Interior and apparently 

 is a continuation under a new name and with slightly altered purpose of the
