MARRIAGE OF THE PRINCESS MARY TO THE PRINCE OF HESSE.

In the beginning of May, the king of Great Britain set out for Hanover, after having appointed a regency, and concerted vigorous measures for distressing the enemy. In a few days after his departure, the spousals of the princess Mary were celebrated by proxy, the duke of Cumberland representing the prince of Hesse, and in June the princess embarked for the continent. About the same time, a sloop arrived in England with despatches from admiral Vernon, who, since his adventure at Porto Bello, had bombarded Carthagena, and taken the fort of San Lorenzo, on the river of Chagre, in the neighbourhood of his former conquest. This month was likewise marked by the death of his Prussian majesty, a prince by no means remarkable for great or amiable qualities. He was succeeded on the throne by Frederick his eldest son, the late king of that realm, who has so eminently distinguished himself as a warrior and legislator. In August, the king of Great Britain concluded a treaty with the landgrave of Hesse, who engaged to furnish him with a body of six thousand men for four years, in consideration of an annual subsidy of two hundred and fifty thousand crowns.
