I began my travels where I purpose to end them viz. at the City of London and therefore my account of the city itself will come last that is to say at the latter end of my southern progress; and as in the course of this journey I shall have many occasions to call it a circuit if not a circle so I chose to give it the title of circuits in the plural because I do not pretend to have travelled it all in one journey but in many and some of them many times over; the better to inform myself of everything I could find worth taking notice of.
