44 Biographical Memoir of 
We are in possession of many highly important letters from 
other European academies, but have not space for more at 
present. , 
The Earl of Cathcart, in his elegant epistle remarks, 
“« There is no person more willing than Iam to render honour 
where honour is so justly due, as it is to the highly venerated 
Jameson.” His Lordship continues, “it will be difficult to 
find a successor to one who has done more than any man 
now living, by his laborious exertions, to enlighten his fellow- 
countrymen, and the world at large, in a department of 
science, which at the commencement of his labours, was in

the pursuit of science, that he himself possessed ; amongst 
whom, during the long course of upwards of fifty years, may

which natural science is cultivated. For myself, who have 
had the privilege of attending Professor Jameson’s class, 
and of accompanying the Professor in some of his geological 
excursions, I cannot say which gave me most pleasure to 
witness, the devoted attention of his pupils to the lucid 
explanation of the phenomena which had come under our 
observation ; or the affectionate regard we all felt for the
