He attended church with unfailing regularity. Punctual to the moment, the form of the Professor was seen to enter church, decorously approach the familiar pew, and enter with grave respect in his whole demeanor. Book in hand, he followed the words of the hymn sung by the congregation, and at the signal for prayer rose erect, his tall figure remaining as motionless as a statue until the prayer was finished. After the service he retraced his steps with decorous gravity and retired to his quarters, to return again with the same punctuality, and conduct himself with the same solemn respect, at the evening service. The hours of Sunday not spent in church were given up to religious reading, meditation, and prayer in his study or in the bosom of his family.
