456 TRAVELS TO DISCOVER 



which followed the march of the army by land, and much 

 difficulty and danger attended the fhipping as they were fail- 

 ing in unknown feas againft the monfoons. Nearchus himfelf 

 informed the king at Babylon of his fuccefsful voyage, who 

 gave him orders to continue it into the Red Sea, which he

We are told it was his intention to carry on the India
