Notwithstanding the poverty of his appearance, his glass was pure crystal, and as he carried it carelessly in his hand, it glittered and sparkled totally unheeded by its owner, till, "Pale, but intrepid, sad, but unsubdued," he raised it slowly between the sun and the thermometer. The effect was instantaneous, and seemed to surprise the holder of the glass as much as it did me. The liquid mounted with considerable effervescence to the point sixty-eight, and would have reached a still higher point, but the glass was withdrawn in seeming disgust. I needed no one to tell me that the bearer of the crystal glass was Dr. PERCIVAL.
