IN GALLOWAY. 



traverses three times the junction of the stratified 

 country with the granite, the eastern junction of 

 the Loch Doon mass, as I have already stated, near 

 Craigencaillie, and both eastern and western junc- 

 tions of the Dee mass, viz. the western junction 

 at the Bridge of Dee, and the eastern one at the 

 east end of Strone Loch, about four miles farther 

 down, as I formerly described in my account of 

 the Dee district. 



The distance betwixt the western junction of 

 the Dee granite district with the stratified country 

 at the Bridge of Dee, and the junction of the 

 Doon district on the east, with the stratified rock 

 at Craigencaillie, is four miles, and these appear 

 to be about the nearest points of distance betwixt 

 the two masses. I regret that I have not had it 

 in my power to make the entire circuit of the 

 Doon granite, so as to ascertain its mode of junc- 

 tion with the stratified country on the western 

 side also. I should then have been able likewise 

 to have ascertained more accurately its extent. 

 But as to the latter, we are pretty well inform.ed, 

 seeing we have an account of it from Sir James 

 Hall, who made the above circuit in 1790, as he 

 informs us, in his paper " On the Convolutions of 

 Strata, and their meeting with Granite," publish- 

 ed in the 5th volume of the Transactions of the 

 Royal Society of Edinburgh : he found it to be 

 about eight miles by four.
