The Dutch ship more than one hundred tons of opium annually to Indonesia by 1750.

There are continued Mongol interventions in Tibet throughout the period of Qing rule of Tibet and a reciprocal spread of Tibetan Buddhism in Mongolia.

The Lhasa riot of 1750 takes place in the Tibetan capital Lhasa, and lasts several days.

The uprising begins on November 11, 1750 after the expected new regent of Tibet, Gyurme Namgyal, is assassinated by two Manchu ambans.

During the uprising against Chinese authority both ambans are murdered by the mob, and fifty-one Qing soldiers and seventy-seven Chinese citizens are killed.

The nearest bridge to London Bridge was, for over six hundred years, at Kingston.

A bridge over the Thames at Westminster had been proposed in 1664, but opposed by the Corporation of London and the watermen.

Despite further opposition in 1722, and after a new timber bridge was built at Putney in 1729, the scheme received parliamentary approval in 1736.

Financed by private capital, lotteries and grants, Westminster Bridge, a road and foot traffic bridge designed by the Swiss architect Charles Labelye, was built between 1739–1750.

The bridge is required for traffic from the expanding West End to the developing South London as well as to south coast ports.

Without the bridge, traffic from the West End would have had to negotiate the congested routes to London Bridge such as the Strand and New Oxford Street.

Roads south of the river are also improved, including the junction at the Elephant & Castle in Southwark.

John Michell studies magnetism and discovers the "inverse-square law", the fact that the magnetic force exerted by each pole of a magnet decreases in proportion to the square of the distance between them.

His 1750 paper Treatise of Artificial Magnets, which is written for seamen and instrument makers and intended as a practical manual on how to make magnets, includes a list of the "Properties of Magnetical Bodies" that represent a major contribution to the understanding of magnetism.

In a work of some eighty pages, he presents an easy and expeditious method of producing magnets that are superior to the best natural magnets.

Besides the description of the method of magnetization which still bears his name, this work contains a variety of accurate observations about magnetism, and features a lucid exposition of the nature of magnetic induction.

John Michell was born in 1724 in Eakring, in Nottinghamshire, the son of Gilbert Michell, a priest, and Obedience Gerrard. Gilbert was the son of William Michell and Mary Taylor of Kenwyn, Cornwall; Obedience was the daughter of Ralph and Hannah Gerrard of London.

He is educated at Queens' College, Cambridge, and will become a Fellow of Queens.

The Skidis are reported in 1750 to be ruled by a grand chief who has nine hundred warriors.

The British response to the Acadian exodus accelerates it.

Cornawallis orders, for example, Captain John Handfield and two companies of troops to Fort Vieux Logis in Grand Pre with instructions to patrol the roads to prevent Acadians from leaving.

Patrols also happen throughout the Cobequid. (On one such patrol, Noel Doiron’s priest Jacques Girard had been arrested. This action had precipitated Doiron leaving Noel, Nova Scotia for Point Prime, Ile St. Jean in the spring of 1750.)

The British eventually forbade all assemblies of the Acadians, and they have been ordered to supply the British commanders with provisions and offer their labor on demand, at prices set by regulation.

Not surprisingly, many Acadians refuse to supply the British, and by the summer of 1750 Acadians by the hundreds are in flight from the province.

Gilman had left unannounced for New England by April 1750.

By July, Cornwallis had given the saw mill to Clapham to manage.
