although it is more rare to find them sufficiently perfect to make them 

 worth preserving. 



In the localities near Peterhead, there have been found " considerable 

 varieties of the Echini family, occasionally entire, but more frequently 

 only small portions of the impressions of these shells are found. Single 

 spines frequently occur, and are distinctly marked. The Inoceramus, 

 Pectens, and Terebratulae, are very abundant." 



Flints are also found on the surface, ou the hill of Skelmuir, adjoining 

 Bogingarry. This hill is separated from that of Kinmundy by a valley, 

 and a deep morass called the bog of Ardallie. South-westward they 

 are found again on the hill of Dudwick, in the parish of Ellon. This 

 seems to be their southmost limit. 



I learn fi'om a paper of Mr. Christie s, of Banff, published in the 

 Edinburgh Philosophical Magazine, for 1831, that they occur, as already 

 alluded to, at Boyndie bay in that shire ; and also in a mass of 

 diluvium covering the high grounds between Turriff and Delgaty Castle. 

 The flints at Boyndie bay are found strewed along the shore, and contain 

 traces of zoophytic organic remains. Those at Delgaty are likewise 

 characterised by similar remains. The station at the latter place is ten 

 miles from the sea, and is the highest ground in the neighbourhood. The 

 flints are found in a mass of diluvial clay, cresting the hUls. Xoae arc 

 found in the hollows. 



In iny collection of fossils from Bogingarry and adjoining localities, 

 there are impressions of portions of spines, and also casts of at least three 

 varieties of the Echinus. There are also casts of Inoceramus, Terebratula, 

 Pecten, Plagiostoma, Turbinolia, and Flustra, together with other remains 

 not easily made out. From the remains in the flint, existing only as 

 casts and imi^ressions, it is very difficult, indeed it is almost impossible, 

 to make out any of them with sufficient certainty to name them. 



The other rocks in the immediate neighbourhood of the Bogingarry 

 chalk flints, are gi-anite, trap, and limestone. We have northwards, 

 white granite at Smallburn, red at Newton and Greenmyie. The rising 

 ground on which the house of Kinmundy stands, is a greenstone trap. 

 Nothing but trap was met with in digging the foundation of the house ; 

 it was also met with along with a loose gravel below it, in sinking the 

 well close by, 46 feet deep. Trap comes to the surface in the wood 

 behind the house, and is quamed for dikes and drains. In the hollow 

 behind, at Causey-ford, wc have a deep deposit of peat. On the south 

 side of Millhill, granitic gravel. On the north side, granite quarried 

 for building purposes. Below Barnyards on the burn side, we have a 

 sort of mica slate. West fi-om that, above the hills of Coynach and 

 Knock, there are immense boulders of clinkstone. These are water-worn : 

 some of them are many tons in weight. Four miles further, at Hythie, 

 limestone resting on granite. 



North-westward, at Annochie, we have limestone quarried for burning. 

 It is much cut by veins, dikes, and blocks of gneiss, from which we
