from whence we may conclude, the eclipse began at London about 31 or 32 

 minutes after 4 the same morning. Mr. Brattle found, that at 44 minutes 

 after 11 at night, part of the moon's disk looked somewhat duskish, and that 

 at 52 minutes, the shadow was well entered; so that from hence, as well as 

 from a comparison of the ingress and egress of the principal spots, it probably 

 began there about 49 minutes after 11; whence it follows, that Cambridge in 

 New England lies 4'' 424-"", or TCf 37' to the westward of the meridian of 

 London. 



I happened to see the moon the same morning at 35 minutes after 5, when 

 she wanted at most but 3 minutes of being totally eclipsed ; so that at London 

 she immerged at 38 minutes past 5. Mr. Brattle saw her immerge exactly at 

 54 minutes after 12; whence it follows, that the difference of the meridians, 

 found by comparing these observations, is 4** 434-'", or 70° 52', agreeing very 

 well with the former; so that by taking a mean between them, the difference 

 of longitude of the 2 places is 4** 43 , or 70°, 45'.

* We find no particulars relative to the life of Dr. Harris, the author of this first real Dictionary 

 of the Arts and Sciences, as to the state in which they then were. Some years after the above, a 

 second volume of the same was published, in a new alphabet, in the title of which he is stiled 

 " late Secretary of the Royal Society." A third volume was afterwards added, but it is supposed a 

 compilation by the booksellers. He seems to have been a patron of the mathematical Wm. Jones, 

 Esq. the friend of Sir Isaac Newton, vice-president of the Royal Society, and father of the late Sir 

 Wm. Jones, the celebrated Indian Judge: as Mr. Jones dedicated to the Rev. Mr, John Harris his 

 Treatise on Navigation, published in 1702, in whose house Mr. Jooes says he composed his 

 said book.
