SIMMONS — EVIDENCE OF GLACIAL ACTION IN SCOTLAND. 163 
cestors of Pty. 3fortoni, from the American Greensand, may be repre- 
sented in time by some of the species of Acrodus, we would invite 
comparison with an unnamed tooth of this genus from the Forest mar- 
ble of Stanton, in Wiltshire. In the same way, if the development 
theory be correct, the connecting links might be hereafter discovered 
between the more primitive Orodus ramosus of the Carboniferous 
limestone and the Forest Marble species of Acrodus, and the Acrodus 
Anningicd of the Lias of Lyme Regis. 
NOTES ON THE EVIDENCE OF GLACIAL ACTION 
IN SCOTLAND. 
By p. Simmons, Esq., of Whiteinch. 
In the parish of Baldernock, county of Stirling, and in the neigh- 
bourhood of "fragments of stone reared by creatures of clav," 
Craigmadden Castle, the pedestrian will find three large stones well 
worthy of his notice. They are situated in the centre of a bog ; 
consequently, if the said pedestrian desires to observe, measure, and 
minutely examine them, he must, as three friends lately did, take off 
boots and stockings and wade through the water tliat surrounds the 
stones to within two feet ; that 
is to say, if he desires such arti- 
cles to remain dry. The bog 
forms part of an extensive na-

the Craigmadden moor ; and the 
stones have received the name Fig. 1.— View (looking to the S.E.) of the 
*'Auld Wives' Lifts," from the "Auld Wives' Lifts." 
absurd tradition that they were placed, once upon a time, among the 
heather by three old women, natives of Baldernock, Strathblane, and 
Campsie. 
The Lifts are considered by some antiquaries to be nothing more 
or less than a cromlech or sepulchral monument ; others, however, 
think they are an altar which the Druids used. The former opinion 
is maintained by Dr. Daniel AVilson in his 'Archaeology.' J-lis 
words are : " It is remarkable as an example of a trilith, or com- 
plete cromlech, consisting only of three stones. Two, of nearly equal 
length, support the huge capstone ; a block of basalt measuring fully 
18 feet in length, by 11 in breadth, and 7 in depth. A narrow tri- 
angular space remains open between the three stones, and through 
this every stranger is required to ])ass on first visiting the spot, if, 
according to the rustic creed, he would escape the calamity of dying 
childless. It is not unworthy of being noted, that though the site of 
this singular cromlech is at no great elevation, a spectator standing 
on it can see across the island from sea to sea ; and may almost at
