most fragile frame throughout his life. His works constitute an amazing monument of industry. But during the years he had been tutor in Sir John Hartopp’s family he must have performed these duties in a spirit of remarkable conscientiousness, for he prepared some of the works which afterwards delighted and instructed the world, as the necessary means of the course he was pursuing in the education of the young man, his pupil. Very remarkably this is the case with his “System of Logic,” which when it was published many years after was adopted and continued to be until recently the text-book for the Universities of Oxford and Cambridge; this appears also to have been the case with his “Scheme of Ontology.” He refers to many of his writings published at a much later period of his life, as for the most part the productions of these his earlier years. We shall have occasion to speak of these again; at present it is sufficient to refer to this persistency of mental labour and assiduous industry as not only the sufficient cause for the illness which suspended him from labour, but the foundation of future years of painful infirmity which accompanied him through life. There must have been much about him not only to command respect but to enchain affection. Long hesitating as to whether he should accept the proffered pastorate, he had not long entered upon the real responsibilities of his office before he was again seized with a painful and alarming illness; almost immediately he was compelled again, in July, 1702, to renew his rest in Southampton, and then returning to London he mentions, in the memoranda we have already quoted, that he was “seized with violent gaundise and colic three weeks after my return to London, and had a very slow recovery, eight or nine weeks’ illness. From September 8th, or thereabouts, to November 27th or 28th. This year, viz., 1702, by slow degrees removed from Newington to Thomas Hollis’s, in the Minories.”
