Letter from Mordaunt Martin of 'Burnham' to Dr [John Coakley] Lettsom, Sambrook House, London, 8 Mar 1801. Stating that he has despatched to Lettsom a parcel of mangelwurzel seeds. Explaining that he was prevented from answering Lettsom's letter of 3 Jan by an attack of gallstones, since relieved by pills of soap and rhubarb. Discussing the 'Brown Bread Act' [probably 41 Geo.3.c.16] to which, he says, Lettsom was in some degree accessory; quoting Lettsom and Horne Tooke on the Act; Martin prefers brown bread for his breakfast, using his own wheat 'sifted in the coarsest hair sieve', but deprecates the 'indiscriminate use of it'. Attacking at length the Potato Premium Bill, which had just been rejected, according to 'the paper of this night'; claiming that such a bill would force by premiums an unnatural produce on land which the occupiers could use for more profitable crops. Adding that his and Lettsom's 'hearts will beat in unison' on reading pages 109-110 of the 2nd edition of [Robert] Fellowes's Christian Philosophy [1799].
