An unrecorded William Allen caricature?

A CARICATURE relating to the marriage of William Allen, F.R.S., (1770-1843) to Grizell Birkbeck, widow of Wilson Birkbeck, has recently come to light. It bears the title 'THE ATTRACTION OF GRAVITY !!!, the space being filled with a plough (Allen's pharmacy was in Plough Court, Lombard Street, London) and the subheading: 'Eye Natures walks shoot Folly as it flies'. This coloured engraving, by an artist yet unidentified but who may be Thomas Jones or possibly Robert Cruikshank, is not recorded in Mrs. D. M. George's Political and Personal Satires for 1827 nor is it in the catalogue of the Print Room at the British Museum. It must have been published in March 1827, the month in which the wedding took place, as were six other caricatures relating to the wedding. These are Sweet William and Grizell or Newington Nunnery in an Uproar (Robert Cruikshank, 5 March 1827, an uncoloured version of which was published by Henry Heath), Racing Intelligence or Money Makes the Mare to Go (Robert Cruikshank, 8 March 1827), Humming All the Trade is or The Modern Alchemist (T. Jones, 8 March 1827), Willy the Lion-Insulted by Asses (G. Williams, 1827) The Loves of Willy and Grizzy (Henry Heath, 14 March 1827-a small coloured engraving with doggeral verses below) and Yea, Verily the Spirit Moveth-The Wedding of Willy and Grizzy (? Henry Heath, 14 March 1827, a small print with doggerel verses). The coloured engraving now described carries the wording: 'Sweet Grizzy, we have long spoken the truth together, verily now let us lie together-If the friends animadvert upon thee or me, they shall find I am a Reciever (sic) that can give them a Retort! !.' The words 'Reciever' and 'Retort' had reference to Allen's business as an apothecary. The drawing shows Grizell and Allen holding hands, both dressed in the Quaker style of the period. The reason this marriage called from the caustic pens of the caricaturists of the time such severe lampooning of Allen was the consternation that it caused among the Friends, not only in London but throughout the country. Allen, a minister of the Friends, was a public figure, internationally known for his antislavery views, for his connections with the Royal House, for his visits to the Czar of Russia, and for the prominent position he held in London pharmacy. When the Pharmaceutical Society of Great Britain was formed in 1843 Allen was called upon to be its first president. In 1827 Allen was 57 years old and his bride, Grizell, 69. Allen had been married twice before: Grizell had been fifteen years a widow since the death of Wilson Birkbeck in 1812. Lucy Bradshaw, in her three-volume Life and Correspondence of William Allen" notes that about March 1827 Allen mentions in a letter to a friend that a new epoch is opening in his eventful life, that for years he and Grizell Birkbeck had been upon terms of friendship and that he often sought her help and counsel. Not until he lost his beloved child, his last earthly prop, did a more intimate union than that of friendship appear. They, Allen and Grizell, purpose that the marriage should take place on the 14th instant (March). Allen added: 'Should this step appear singular let it be remem-
