These sub-provinces do not differ very materially in size. 

 The smallest, Ossor}', contains 2,043 sq. miles, and the largest, 

 Ormond, contains 3;3 16 sq. miles, the average area being 2,710 

 sq. miles. Each sub-province contains at least one mountain 

 over 2,000 ft. high, with the exception of Oriell, where the 

 highest point, Slieve Ban, is 1,935 f^' 



The limits of each province, sub-province, and county or 

 vice-county are shown on the accompanying map (Plate 7). 

 It will be observed that the divisions of the coast line are such 

 that they can easily be grouped into a northern and a 

 southern series of six each by a line extending from near 

 Balbriggan to Killary Ba}'. They can also be grouped into 

 an eastern and a western series of six each by a line drawn 

 from Lough Foyle to Kinsale Harbour.
