Thornhill has never been without its Gideon Gray. Had Dr John Brown been acquainted with its record in this particular respect he could have added to that remarkable chapter of his _Horoe Subsecivoe_ the names of not a few medical benefactors, the memory of whose services is yet fragrant in our midst. Scattered here and there in many a quiet country kirkyard are the graves of heroes of science who in their day ungrudgingly gave of their very best, faithfully ministering to the wants of the poor and needy without thought of fee or reward; men of ability, intellect, tact, and courage of heart, whose life-work lay in the sequestered bypaths, and whose names were unknown outside the glen they called their home. Of such was Dr Grierson; and as he stood by my bedside the thought momentarily flashed through my mind, would that he had been limned by Scott or by the creator of Rab and Ailie! A little over medium height; wiry, spare, and alert; broad shoulders slightly stooped; long dark hair streaked with gray, without a parting, brushed straight back from his forehead and hanging in clustering locks above his stock; his face serious almost, yet not void of humour, and lit up by kindly, blue, thoughtful eyes; a presence cheering and reassuring, and a bearing which bespoke the scholar and the gentleman. His clothes were of rough gray homespun, badly fitted and carelessly worn. A thin shepherd-tartan plaid, arranged herdwise, hung from his shoulder, and he held in his hand a round soft hat, gray-green from exposure to summer sun and winter rains. Such was the man who stood by my bedside--a Gideon Gray indeed--strong of purpose, keenly observant; shy, yet not suspicious; revelling in his power of doing good; inured to cold and privation; buoyant and hopeful in the face of difficulties; daily in close and loving communion with all nature around him; and girt about with truthfulness and integrity as with a cloak. Though I had never before been in his presence, I hailed him within my heart as a true and honoured friend. He shook hands without saying good-morning, and seated himself on a chair at the foot of my bed. Betty, who had preceded him upstairs, and announced him, walked across the room, took up a position at the gable window, and feigned an interest in our grocer neighbour's back-yard. He looked at me pointedly and earnestly, the while stroking his long straggling beard, and then, half-turning his head toward Betty, he said with a low, little laugh, and with a pronounced yet euphonious 'burr,' 'Our young friend, Betty, is more of a Kennedy than a Russell.' 'Ay, doctor, that he is,' said Betty, without taking her eyes from the window. 'He aye took efter his mither's folk. When he was a bairn o' three he was the very spit o' his aunt Marget. Not that I ha'e ony recollection o' her, but that's what I mind the mistress used to say.'
