144 Mr Anderson on the Organic Remains in 



Law, at an elevation, as compared with its emergence from the 

 bed of the river, of about 700 feet. The texture of this rock 

 is finer and more compact than the red variety, consists essenti- 

 ally of clay with very little siliceous matter, and contains a con- 

 siderable quantity of mica, which causes it to decompose in thin 

 plates. There are very few nodules of either clay or quartz 

 in it. 



Towards the lower part of this rock, there are two beds of a 

 slaty clay, one of which is more highly indurated than the other, 

 and of a lighter colour. These may be observed upon the 

 beach at Wormit Bay, near the fisher's lodge, the dark-co- 

 loured at once attracting the eye by its coaly aspect. Both of 

 them are very friable, and softened into an unctuous clay by the 

 constant action of the tide- wave. The light-coloured bed con- 

 tains more mica than the other, and is divisible into thin laminae, 

 between which the flattened stems of vegetables occur in the 

 greatest abundance. Numerous circular forms, from half an 

 inch to about an inch in diameter, are intermixed with the mi- 

 nute gramineous culms, but in no instance have I found them con- 

 nected so as to form an entire plant. The bed at Parkhill, 

 about ten miles to the westward, differs very little from that 

 which has been described, except in its fossil and slaty struc- 

 ture, bluish colour, and greater hardness. It is, in all probabi- 

 lity, a continuation of the same, as the vegetable impressions, in 

 both localities, seem to be identical in their specific characters. 

 " These occur," says Dr Fleming, " in the form of circular flat 

 patches, not equalling an inch in diameter, and composed of 

 numerous equally contiguous circular pieces, not' unlike what 

 might be expected to result from a compressed berry, such as 

 the bramble and the rasp." 



Differing from Dr Fleming as to the position of the grey 

 sandstone, which he places above the old red rock, I shall state 

 a few of the localities from which I have obtained specimens 

 containing the same vegetable impressions, and which clearly 

 warrant the inference as to its inJe)-ionty in the order of super- 

 position. 



The colour and texture of the Wormit Bay grey sandstone 

 very closely resemble those of the Kingoodie reck, so extensive- 

 ly used in building, and which occupies a corresponding posi-
