Ebiules include Hyke and Bum, also with their adjacent islets. — 

 East and West Ross are separated by a line traced along the 

 water-shed between the eastern and western coasts ; East Boss 

 being considered to include those detached portions of Nairn, 

 situate to the westward of the Murray Firth and Loch Beauly. 

 The fragmentary county of Cromarty may belong to East or 

 West Boss, according to the geographical position of its 

 detached fragments. — FJast and West Sutherland are also sepa- 

 rated by the line of water-shed ; this being so traced as to 

 divide the south-eastern portion of the county from the western 

 and northern." 



The three groups of North Isles, namely, Hebrides, Orkneys, 

 Shetlands, are at once treated as so many sub-isrovinces and so 

 many counties ; and they are numbered accordingly. The other 

 counties of Britain being undivided into vice-counties, their 

 boundaries do not require special explanation here.
