With the single exception of Richard Baxter, no clergyman of eminence on record appears to have suffered so acutely or for so long a period from nervous disorders as this eloquent divine. So little, unfortunately, is known of the nature of his disorder, that it would be unjust to express any opinion as to the urgency of the temptation which drove him to the enormous consumption of opium in which he indulged. His biography by Olinthus Gregory sufficiently indicates the severity as well as the early manifestation of his painful disorder. "At about six years of age he was placed at a day-school about four miles from his father's residence. At first he walked to school in the morning and home again in the evening. But the severe pain in his back, from which he suffered so much through life, had even then begun to distress him; so that he was often obliged to lie down upon the road; and sometimes his brother and his other school-fellows carried him in turn.
"Sir James Macintosh described Mr. Hall, when in his twentieth year, as attracting notice by a most ingenuous and intelligent countenance, by the liveliness of his manners, and by such indications of mental activity as could not be misinterpreted. His appearance was that of health, yet not of robust health, and he suffered from paroxysms of pain, during which he would roll about on the carpet in the utmost agony; but no sooner had the pain subsided than he would resume his part in conversation with as much cheerfulness and vivacity as before he had been thus interrupted.
"At that period, though he was strong and active, he often suffered extremely from the pain to which I have before adverted, and which was his sad companion through life. On entering his room to commence our reading, I could at once tell whether or not his night had been refreshing; for if it had, I found him at the table, the books to be studied ready, and a vacant chair set for me. If his night had been restless, and the pain still continued, I found him lying on the sofa, or more frequently upon three chairs, on which he could obtain an easier position. At such seasons, scarcely ever did a complaint issue from his lips; but inviting me to take the sofa, our reading commenced. They, however, who knew Mr. Hall can conjecture how often, if he became interested, he would raise himself from the chairs, utter a few animated expressions, and then resume the favorite reclining posture. Sometimes, when he was suffering more than usual, he proposed a walk in the fields, where, with the appropriate book as our companion, we could pursue the subject. If _he_ was the preceptor, as was commonly the case in these peripatetic lectures, he soon lost the sense of pain, and it was difficult to say whether the body or the mind were brought most upon the stretch in keeping up with him.
