Sir

I was very much interested by an abstract of your paper which appeared some time since in the Scotsman.² Having learnt your address, through the kindness of M^r. Walker,³ I trust you will excuse the liberty I take in addressing you, and that will do me the pleasure of accepting a copy of my paper on Glen Roy.—⁴ I wish very much to know, whether your paper is printed anywhere at greater length than in the Scotsman? I should feel much obliged if you would answer me this question, & at the same time perhaps you will be good enough to inform me, whether any more facts have been discovered, & whether your views on the origin of the terraces round the summit of the Eildons have been confirmed, or the contrary?—⁵ I should much like to know by what means you have estimated the height of the terraces above the sea, and their corresponding level on the different hills?⁶ Over how many miles of country have traces of these marks at the same level been observed? Should you feel so inclined, any observations on th⁠⟨⁠is⁠⟩⁠ subject, which you would have the kindness to communicate with me, I should receive with the greatest interest.— I had intended to have visited your part of Scotland this summer, but the state of my health renders it very doubtful, whether I shall be able. I should have much enjoy⁠⟨⁠ed⁠⟩⁠
