    Object history
    In October of 1762 Malpighi sent the Royal Society an extensive account [MS/103/1] of the development of the chick in an egg as a follow up to his earlier Dissertatio Epistolica de Formatione Pulli in Ovo (1673) on the same subject.

    It was read at the Royal Society on 22 January 1673 [JBO/5, pp.6], ordered for printing two years later on 17 June 1675 [CMO/1/221], and published as the appendix to Malpighi’s Anatome Plantarum (1675), along with seven illustrative plates.
