Conversazione to mark the 300th anniversary of the publication of the Philosophical Transactions of the Royal Society, Hooke’s Micrographia, and Evelyn's Sylva

Her Majesty Queen Elizabeth the Queen Mother and His Majesty King Gustav Adolf of Sweden honoured the Society by their presence at a conversazione on 16 November 1965 to celebrate the 300th anniversary of the publication of the Philosophical Transactions. Professor Andrade, F. R. S. , in his account of the early history of the Transactions (1) has told how they were edited by Henry Oldenburg from 1665 until his death in September 1677, and how with the last part of the twelfth volume, which appeared four months later, they ceased publication for four years. The first twelve volumes thus constitute a definite period in the history of the Philosophical Transactions, and the exhibits focussed on this period, with a special interest in Robert Hooke and Micrographia, and in the husbandry of the period.
