Letter from William Allen, London, to Robert Were Fox, Falmouth Allen has dispatched barometers to Falmouth by the brig 'Susan'. He has been practising with a similar instrument at Brighton and notes his experiences in using and transporting the device. On behalf of his committee, he thanks Fox for his support on the education of the poor, 'next to the abolition of the slave trade it is one of the most important subjects in a moral and political point of view'. 30 September 1809
