Kinghorn Loch (see Plate CXVI.) is a small deep basin about half a 

 mile from Kinghorn on the northern shore of the Firth of Forth. It 

 is sub-circular in outline, and about one-third of a mile in maximum 

 diameter, covering an area of about 30 acres. The basin is simple, with 

 the maximum depth of 38 feet centrally placed, but towards the southern 

 shore. The volume of water is estimated at 20 million cubic feet, and the 

 mean depth at over 15 feet. When surveyed on May 19, 1905, the eleva- 

 tion was 203*4 feet above the sea, as compared with 205*2 feet found by the 

 Ordnance Survey on May 4, 1893. The following temperatures taken in 

 the deepest part show a constant temperature from the surface down to 

 20 feet, and then a fall of 4 Fahr. between 20 and 30 feet :

Loch Fitly (see Plate CXVI.) lies about 3 miles north of the town of 

 Dumfermline in Fife, and 5 miles south of Loch Leven. It trends nearly 

 east and west, and is nearly a mile in length, and practically uniform in 

 width, the maximum breadth being about one-third, and the mean breadth a 

 quarter, of a mile. The superficial area is about 143 acres, and the drainage 

 area about 9 square miles. The loch forms a simple basin, with the deeper 

 water lying along the southern shore, where an artificial bank has been 

 built across, off which the maximum depth of 16 feet was found ; the small 

 part of the loch cut off by the embankment has a maximum depth of 

 12 feet. The volume of water is estimated at 46 million cubic feet, and 

 the mean depth at 7J feet, fully two- thirds of the bottom being covered by 

 less than 10 feet of water. The loch was surveyed on May 12, 1905, when 

 the elevation was 412'8 feet above the sea, as compared with 413'0 feet 

 determined by the Ordnance Survey officers on March 22, 1894. The 

 temperature at the surface was 53*0 Fahr., and at a depth of 15 feet 52-0. 



Loch Gelly (see Plate CXVI.) lies about 4 miles to the east of Loch 

 Fitty and about the same distance south-east of Loch Leven. It is a broad, 

 shallow, flat-bottomed basin, three-quarters of a mile in length from east to 

 west, by nearly half a mile in maximum breadth. The superficial area is 

 about 148 acres, and the drainage area about 2J square miles. The 

 maximum depth is 9 feet, and the mean depth 5 feet, the volume of water 

 being estimated at 32 million cubic feet. When surveyed on May 11, 

 1905, the elevation was 351*2 feet above the sea, almost identical with
