tonne

Is there any specific account of the "tonne in Cornhyll" existing?

The letter of Mr. Kidder relative to the "pretty pynnace of about thirty tonne," is again referred to by your correspondent.

He says it was "a pretty Pynnace of about some thirty tonne."

When he comes to large weights, does he not commonly abjure the 1,000 kilos and write one tonne?
