"Mr.Kendal's watch" is the subject of frequent notices in Captain Cook's account.

At the Cape of Good Hope, it is said to have "answered beyond all expectation." Further south, in the neighbourhood of Cape Circumcision, he says, "the use of the telescope is found difficult at first, but a little practice will make it familiar.

By the assistance of the watch we shall be able to discover the greatest error this method of observing the longitude at sea is liable to." It was found that Harrison's watch was more correct than Arnold's, and when near Cape Palliser in New Zealand, Cook says, "this day at noon, when we attended the winding-up of the watches, the fusee of Mr.Arnold's would not turn round, so that after several unsuccessful trials we were obliged to let it go down." From this time, complete reliance was placed upon Harrison's chronometer.

Some time later, Cook says, "I must here take notice that our longitude can never be erroneous while we have so good a guide as Mr.Kendal's watch." It may be observed, that at the beginning of the voyage, observations were made by the lunar tables; but these, being found unreliable, were eventually discontinued.
To return to Harrison.

He continued to be worried by official opposition.
