As this coal occurs in the heart of the south-west iron ore region, it 

 would be of great economic importance if more reliable in quantity and of 

 better quality. The subjoined analysis of a fair sample at once shows its

SOME FACTS CONCERNING PAST VISITATIONS OF CHOLERA. 



The first detailed account of the disease that is now commonly called 

 either cholera, or Asiatic cholera, was published early in the i6th century, 

 and during that century many successive descriptions of the disease exhib- 

 ited its extreme violence and mortality. To the Portugese who invaded
