The eclipse of April 8, 1652, is another of those Scotch eclipses, as we may call them, which left their mark on the people of that country. Maclaurin[94] speaks of it in his time (he died in 1746) as one of the two central eclipses which are “still famous among the populace in this country” [Scotland], and “known amongst them by the appellation of Mirk Monday.” The central line passed over the S.E. of Ireland, near Wexford and Wicklow, and reaching Scotland near Burrow Head in Wigtownshire, and passing not far from Edinburgh, Montrose and Aberdeen, quitted Scotland at Peterhead. Greenock and Elgin were near the northern limit of the zone of totality, and the Cheviots and Berwick upon the southern limit. The eclipse was observed at Carrickfergus by Dr. Wyberd.[95] Hind found that its duration there was but 44s. This short duration, he suggested, may partly explain the curious remark of Dr. Wyberd that when the Sun was reduced to “a very slender crescent of light, the Moon all at once threw herself within the margin of the solar disc with such agility that she seemed to revolve like an upper millstone, affording a pleasant spectacle of rotatory motion.” Wyberd’s further description clearly applies to the Corona. A Scotch account says that “the country people tilling, loosed their ploughs. The birds dropped to the ground.” The eclipse of November 4, 1668, visible as a partial one in England, was of no particular interest in itself but deserves notice as having been observed by Flamsteed,[96] who gives a few diagrams of his observations at Derby. He states that the eclipse came on much earlier than had been predicted. It was well known at this time that the tables of the Sun and Moon then in use were very defective, and it was a recognition of this fact which eventually led to the foundation of the Greenwich Observatory in 1675. On September 23, 1699, an eclipse of the Sun occurred which was total to the N. of Caithness for the very brief space of 10-15 secs. At Edinburgh, about 11/12ths of the Sun’s diameter was obscured. In the Appendix to Pepys’s _Diary_[97] there is a letter from Dr. Wallis mentioning that his daughter’s attention was called to it by noticing “the light of the Sun look somewhat dim” at about 9 a.m., whilst she was writing a letter, she knowing nothing of the eclipse.
