The passage in the memoir as to the exact period is more than usually vague.

The writer is dealing with the year 1800, and he proceeds: "My father, now about his forty-sixth year, was much more stout and healthy than when I first remember him.
Soon after that early period he became subject to vertigoes, which he thought indicative of a tendency to apoplexy; and was occasionally bled rather profusely, which only increased the symptoms.

When he preached his first sermon at Muston in the year 1789 my mother foreboded, as she afterwards told us, that he would preach very few more: but it was on one of his early journeys into Suffolk, in passing through Ipswich, that he had the most alarming attack." This account of matters is rather mixed.

The "early period" pointed to by young Crabbe is that at which he himself first had distinct recollection of his father, and his doings.

Putting that age at six years old, the year would be 1791; and it may be inferred that as the whole family paid a visit of many months to Suffolk in the year 1790, it was during that visit that he had the decisive attack in the streets of Ipswich.
