Object history
At the meeting of the Royal Society on 28 November 1667, ‘Mr. Oldenburg produced a letter written to him by Renatus Franciscus Slusius, canon of Liege, dated there 24 November, 1667, N. S. giving an account of his method of reducing an equation of the fourth degree or biquadratic into two quadratic equations, by a circle and a parabola; and expressing his great respect to the society. It was ordered, that the secretary should return him the thanks of the society, and that Mr. Hooke and Mr. Collins should have a copy of the letter to consider, whether Mr. Slusius had effected what he had undertaken’ (Birch 2:217-18). Oldenburg’s reply is dated 25 November 1667.
