Introduction. 



[Abridged.] 



[Before entering upon the special subject of his Memoir, Mr. Bain gives a 

 sketch of the progress of his geological researches in South Africa, and refers to

 some time been engaged in carrying out an extensive system of Military Roads. 



As the basis for his operations, Mr. Bain has used the excellent Ordnance Map,
