ON THE OCCURRENCE OF FRAGMENTS OF GARNET IN THE 

 MILLSTONE-GRIT. BY W. C. TREVELYAN, ESQ. 



To the Editors of the Philosophical Magazine and Journal of Science. 

 Gentlemen, 

 About the year 1 826, 1 found dispersed rather abundantly in parts 

 of the millstone-grit rock of Shaftoe in this neighbourhood, small, 

 angular, transparent fragments of garnet : since that time I have met 

 with them in similar rocks of the coal-fields near Kirkstall in York- 

 shire, and Stirling in Scotland, and think that on further exami- 

 nation they may be more extensively observed, as it is probable 

 that these rocks have been formed from the detritus of others, which 

 are known sometimes to contain garnets in great abundance, as well 

 as the other parts of which the millstone-grit is composed, among 

 which I have also occasionally found small rolled fragments of 

 hornblende. 



I shall be glad if you think this notice worth printing in your 

 Journal, for the purpose of drawing the attention of geologists to 

 the subject : And remain. Gentlemen, 



Your most obedient, 

 Wallington, Newcastle- on-Tyne, W. C. Trevelyan.

 a mistake into which I was led by having observed several speci-
