Hall, Cambridge, in 1766. Both father and son were buried in Hendon churchyard. Works Ayloffe's published writings came later in life and were no great success with the general public. In 1751 he sent out proposals for printing by subscription the debates in Parliament before the Restoration in eight octavo volumes. Little favour was apparently extended to the scheme. Although in 1773 it was advertised that the first volumes would soon go to the press, none appears to have been published (cf. Rawlinson MSS. in the Bodleian, s. v. 'Ayloffe'). Also in 1751, Sir Joseph issued a prospectus for subscribers to a translation of Diderot's and D'Alembert's Encyclopédie, with additional or expanded articles on subjects of English interest, but the first number, published on 11 June 1752, obtained scanty support and was severely handled in the Gentleman's Magazine (xxii. 46), so that the project was abandoned. Some years previously, Ayloffe had induced Joshua Kirby, a well-known draughtsman of Ipswich, to prepare some engravings of the chief buildings and monuments in Suffolk. Twelve of them were published with descriptive letterpress by Ayloffe in 1748. It was Ayloffe's intention to introduce Kirby's drawings into an elaborate history of the county upon which he was apparently engaged for the succeeding 15 years. In 1764 he had made such progress in collecting and arranging his materials that he issued a lengthy prospectus for publication of an exhaustive Topographical and Historical Description of Suffolk, but sadly he again received too little encouragement to warrant him in pursuing the plan further. Subsequently, Ayloffe contributed several memoirs to Archæologia, the journal of the Society of Antiquaries, which were highly valued at the time. On 25 February 1763 he "communicated" an interesting Copy of a Proclamation (1563) relating to Persons making Portraits of Queen Elizabeth (ii. 169–170). In 1773 and 1774 there appeared in Archæologia (iii. 185–229,2.39-272, 376–413) three papers by him, describing: A picture at Windsor of the famous interview in 1520 between Henry VIII and Francis I Four pictures at Cowdray near Midhurst, the property of Lord Montague, illustrating Henry VIII's wars in France in the latter part of his reign The opening of the tomb of Edward I at Westminster in 1774, an exhumation that Ayloffe with Daines Barrington superintended. Another paper prepared for the Society of Antiquaries, On Five Monuments in Westminster Abbey, was published separately, with engravings, in 1780. An account of the
