like kind, and wherever the same cause is, tliere will be constantly the same 

 effect. There is a procedure in every part of nature that is perfectly regular and 

 geometrical, if we can but find it out ; and the further our searches carry us,

Account of Loch- Ness. Bij the Rev. Mr. James Fraser, of Kirhhill. 



N° 234, p. 230. 



Loch-Ness, according to our Highland tradition, took its name from Nisus, 

 an Irish hero, who, with Dornadillo his wife, settled a colony in Stratharig. 

 The promontory on which he had his residence is to this day called Doun Dear- 

 nill ; and he being the first that ever off^ered to set out boat or barge upon this 

 lake, it is after him called Loch-Ness. It is 24 miles in length, and in most 

 places 1 in breadth. In many parts of this lake it has been sounded, with more 

 than 500 fathoms of line, but no bottom found. The banks of this lake are 

 high and mountainous, with woods. The lake never freezes, which is imputed 

 to the many great springs and fountains in it : the only fish in it is salmon. 

 This lake discharges itself into a river of the same name, 6 miles in length, 

 which never freezes, but always smokes with frost. On the north side of Loch- 

 Ness stands, on a rock, the famous castle of Urqhart; the great ditch round it 

 was for tiie most part cut out of the rock, and received water from the lake. 

 This castle consisted of 7 great towers, and it is said was built by the Cuminees, 

 or Cumings, but was demolished by King Edward the First of England, leav- 

 ing only one tower to the east, still remaining. About 4 miles to the west- 

 ward of this castle, on the side of Loch-Ness, stands that great mountain
