A notice by Sir George S. Mackenzie, Bart, was read to the 
Society, respecting the Vertebra of a Whale, found in a bed of 
dark-bluish clay, near Dingwall, three miles from high-water 
mark. The height above the sea where this vertebra was found 
was 12 feet. The date of its deposition must have bfeen very 
remote, as the great mass of gravel which the rivers of the coun- 
try cut through, is a deposition subsequent to the clay which it 
covers, and in many places peat-mosses have been formed above 
the gravel. Sir George Mackenzie presented the vertebra to 
the Society’s Museum.
