Isaac Dalby

[1][2] The venture failed, and in 1772 he arrived in London, and obtained an appointment as teacher of arithmetic in Archbishop Tenison's School in Lambeth.

[1][2] This arrangement was broken up by the death of Beauclerk in 1780; in the following year Dalby was appointed mathematics master in a naval school at Chelsea, which later failed.

He held this post for twenty-one years, resigning it in 1820, when old age and infirmity had overtaken him.

He was a contributor to The Ladies' Diary, and was an original member of the Linnean Society of London.

[1][2] Dalby died at Farnham on 16 October 1824, and was buried there at St Andrew's Church.
