Loch Lomond during the Autumn of 1885 333 



Station. The observations at this station at the 

 different dates have, in many respects, greater interest than 

 those made in the Luss basin. The depth here is 100 fathoms, 

 ami is so great that for a thickness of 40 or 50 fathoms above 

 the bottom the change of temperature during the course of the 

 season amounts only to a fraction of a degree, and is so slight 

 as to elude detection, except by using very delicate thermo- 

 meters. The observations made at Inversnaid are collected in 

 Table X, and the results are expressed graphically in the 

 curves (Fig. 5). On the i8th August no observations were 

 made exactly on the Inversnaid station, but observations were 

 ie at two neighbouring stations, Rob Roy's Cave, about a 

 mile north, and Culness, about a mile south of it. The curve 

 has been drawn from the means of the temperatures observed 

 at these two stations.
