1818 Parliamentary Act, under King George III

1818 Parliamentary Act, under King George III -- An intriguing Act carrying an execution (agreement) between His Majesty George III and the King of Portugal for the preventing of traffic in Slaves. Gives details of agreements for Royal Navy Warships to board and seize vessels of both countries trading in slaves but gives (seemingly) exceptions to some Portuguese vessels with "issued paperwork". Mentions among others obscure West African colonies such as "Molembo" and "Cabinda", and also the "Brazils".
