In 1630, Deane published a number of Tracts which had been left more or less incomplete by Samuel Norton. His share in the authorship of the different tracts varies. The titles of one or two will sufficiently indicate the nature of the subjects, and it can be seen that his studies included the philosophical stone, and other subjects receiving attention at the present time, such as "culture pearls." "Mercurius Redivivus, seu modus conficiendi Lapidem Philosophicum." "Saturnus Saturatus Dissolutus et Coelo restitutus, seu modus componendi Lapidem Philosophicum ... e plumbo...." "Metamorphosis Lapidem ignobilium in gemmas quasdam pretiosas, seu modus transformandi perlas parvas ... in magnas et nobilis ..." etc. etc. Edmund Deane married twice, first to Anne, widow of Marmaduke Haddersley of Hull; the date is not known, though it was before the entry of pedigree was recorded in 1612. In 1625, he had a license at York to marry Mary Bowes of Normanton at Normanton. There does not appear to have been a family by either of his wives. He died in 1640, and was buried in St. Crux Church, York. This church was demolished about the year 1885, as it was considered structurally unsafe, but there does not appear to have been any memorial erected to him in the church. The manuscript Registers of the Parish of St. Crux are in the College of Arms: the manuscript extracts do not commence until the year 1678. His Will, however, is preserved. It is dated 30th of Oct. 1639, and was proved at York on the 14th of April, 1640. In a biography it should be the task of the writer to visualise the personality of his subject as well as to record merely the material events of his life. In this instance it would be quite impossible to do so from lack of material, but yet from his works, and from the opinion held of him by Michael Stanhope, and last, but not least, from the contents of his own Will, I think some picture can be painted of him. A man of learning is shown from his writings: a perusal of "Spadacrene Anglica" will exhibit both the clearness of his intellect and the forcibleness of his style. For many years he successfully practised medicine at York. He was held in high esteem among his professional brethren, and was recognized by them as a leader in the profession with a broad mind, ready to listen to and investigate new ideas. His personality is fully and finely revealed in his Will, and as this is the only biography, as it were, written by himself, I append an extract from it, so that he may speak for himself. In the name of God, Amen.
