4 Anniversary Address. 



which for a considerable distance runs nearly along the pre- 

 sent road from Newstead southwards. 



Immediately after breakfast the members divided into two 

 parties — one proceeding to Dryburgh, and a second going to 

 the Eildons to examine the botany and geology of the hills. 



I am informed that little of interest was discovered by the 

 botanists and entomologists. The only beetle captured was 

 the Chrysomela polita ; and among the plants deserving of 

 mention was the Allosorus crispus, or Parsley fern^ grow- 

 ing in great abundance on the south side of the eastmost of 

 the Eildons among the " Glidders." A pretty blue variety 

 of the Viola lutea was found on the top of the same hill, and 

 the Symphytum tuberosum as well as aS'. officinale were also 

 gathered. 



Mr Tate has kindly furnished the following : — 



Notes on the Geology of the Eildon Hills. 

 " Mr Embleton and myself, along with Mr Fryar set off, 

 immediately after breakfast, to the Eildon hills, to examine 

 their botany and geology. We first ascended the highest or 

 middle peak, and then crossed the Col to the northern hill, 

 where Ave were joined by Mr Stevenson and by Mr Curie, 

 to whom we were indebted for much local information. We 

 afterwards descended the hill on the western side. Eildon 

 with its remarkable three peaks is but one hill ; and the 

 whole is essentially of the same geological character. It is a 

 protrusion of porphyry through the greywacke or Cambro- 

 silurian strata, which wrap round the lower parts of the hill. 

 We had an opportunity of examining these strata on the 

 western side of the middle hill, where at a height of about 

 760 feet above the sea, they are highly inclined, being almost 

 perpendicular, and having nearly the usual direction of this 

 formation in the south of Scotland, from south-east to 

 north-west. In one part they are cut through by a porphy- 

 ritic dike, which has so dislocated the strata, that on the 

 north side they are perpendicular, but on the south side dip 

 towards the dike.
