As Humphrey Newton once
wrote:
I never knew him to take any recreation or pastime either in riding out to take the air, walking,
bowling, or any other exercise whatever, thinking all hours lost that was not spent in his studies,
to which he kept so close that he seldom left his chamber unless at term time, when he read in
the schools as being Lucasianus Professor, where so few went to hear him, and fewer
understood him, that ofttimes he did in a manner, for want of hearers, read to the walls. . . . So
intent, so serious upon his studies that he ate very sparingly, nay, ofttimes he has forgot to eat at
all, so that, going into his chamber, I have found his mess untouched, of which, when I have
reminded him, he would reply "Have I!" and then making to the table, would eat a bit or two
