Dr. Berger on the hie of Man. 31 



included along with that of North Bor-roilva, in the trigono- 

 metrical survey of England by Lieut. Col. Mudge. But with these 

 exceptions, no other elevations in the island were ascertaineiJ. A 

 barometical measurement which I have made of nearly all the 

 mountains and other remarkable places, has amongst other advan- 

 tages, enabled me to give a vertical section of the chain throughout 

 its whole extent, which agrees very well with a profile view of the 

 island, taken by Murdoch McKenzIe from the Mull of Galloway. 



The spelling of the Manx names along with their pronunciation 

 and signification has been furnished me by several persons in the 

 isle, well ver^^ed in the knowledge of their native language, but I 

 am particularly indebted for it to the Revds. H. Stowell, T. 

 Howard, and Wm. Fitz-Simmons. 



The length of the island is computed at upwards of thirty Eng- 

 lish miles, of which about five-sixths are occupied by a large body 

 of mountains stretching from North-East to South-West ; its breadth 

 varies from fifteen to eight miles. 



The chain spreads or swells out to the northward contracting 

 itself to the southward into the Calf or Barroiv of Man, which 

 latter is rather less than six hundred acres in superficial extent, 

 offering thus a gradual slope of fifteen hundred and forty feet from 

 the top of Snei-feldt down to Burchet's house on the southern cliff 

 of the Calf, that is to say, a depression of nearly a quarter of a mile 

 in twenty-one miles taken in a straight direction, or, on a mean 

 average, of about seventy-three feet per mile. 



Estimating the mean breadth of the mountainous belt at four 

 miles and a half, and its length at twenty-five, we should have for 

 its superficial extent one hundred and twelve square miles and a 

 half, which when re'^erred to the whole area of the island, on the 

 supposition of its being on a mean average, eleven miles and three
