Observations with the interferometer began in 1965.

So far, however, from promoting the acceptance of the psychological theory, this physical hypothesis proved to have rather the opposite effect, and it began to be dropped by Hartley's followers ( as Joseph Priestley, in his abridged edition of the Observations, 1775 ) before it was seriously impugned from without.

) Observations by Eusebius and Georgius Syncellus can be taken to indicate that Bacchylides might have been still alive at the outbreak of the Peloponnesian War, but modern scholars have differed widely in estimates of the year of his death – Jebb, for example sets it at 428 BC and yet a date around 451 BC is more favoured.
