An Abstract of Meteorological Diaries communicated to the Royal Society, with. 

 Remarks on them hij fV. Derliam, D. D. Canon of IVindsor, and F. R. S. 

 N''423, p. 261. 



Most of these Diaries are accounts of the course and strength of the winds, 

 the heights of the barometer, and the weather, as to rain, &c. ; now of no use. 



Dr. Derham, in his observations, notices that he found a great conformit)' 

 in tlie above articles at different places, at considerable distances. 



Dr. D. remarks that in January 17 1 6, the river Thames was frozen for se- 

 veral miles, and particularly so intensely at London, that whole streets of booths 

 were erected on the ice, oxen roasted, coaches driven, and many diversions 

 exercised above bridge. And so strong was the ice below bridge, as to allow 

 people to walk and skait at their pleasure on it. 



Also that one day in 1715, the wind was so violent, that the Thames was 



emptied from London-bridge as far as , so that only a small rivulet of 



water, no larger than a brook of 10 or 12 feet over, remained; insomuch, 

 that people walked on the bottom, and found treasure there. 



On Feb. 12, 1713-16, Mr. Robie notes an earthquake to have been at Salem 

 village; and on Oct. 21 following the day was so dark, that people were forced 

 to light candles to eat their dinners by. Which could not be from an eclipse, 

 the solar eclipse being the 4th of that month. 



On Feb. 13, 1716-I7, he observed an immersion of the first satellite of Ju- 

 piter, at 10*^ 48' 17"; and on Feb. 8, he observed an emersion at 8^ 7' 30"; ac- 

 cording to which, the difference of longitude between Harvard-College and 

 Upmin&ter, is 4*^ 45', and Mr. Robie says, that it is 4*^ 44' from London, by 

 the latest and best observations. 



Sept. 23, 1717} Mr. Robie, at Harvard-College, New England, observed 

 the solar eclipse.
