NOTE A, Pace 18. 
In the last edition of his “ Elements” (1855), Sir Charles Lyell 
has considerably altered and amplified this description, for which 
he has been to a large extent indebted to the discoveries and pub- 
lications of Mr. Miller. See “ Elements of Geology,” chap. xxvi. 
NOTE B, Pace 40. 
« And in the latter formation [Coal Measures] the first reptiles 
appear.” This statement requires now to be slightly modified, 
in consequence of the discovery in 1851, by Mr. Patrick Duff of 
Elgin, of a true reptile (Telerpeton Elginse) in the Upper Old 
Red of Morayshire. The fact is referred to in “ The Testimony 
of the Rocks,” pages 46 and 104. See also Lyell’s “ Elements ” for 
a figure and description of the creature. The argument follow- 
ing the above quotation is not, however, in any way affected by 
this discovery. It is right, however, to add, that up to a very 
recent period, Mr. Miller was known to have expressed some 
doubts as to whether the rock in which the Telerpeton was found 
did not belong to a much higher formation than the Old Red Sand- 
stone.
