470 t'HILOSOPHICAL TRANSACTIONS. [aNNO 1740. 



A Conjunction of Planus and Mercury, May 17, 1737, observed at Greenwich. 

 By J. Bevis, M. D. N° 459, p. 630. 



At 9'' 44", the planet Mercury appeared immediately under Venus, their 

 distance asunder not more than a 10th part of the diameter of the latter. 



An Occultation of Aldeharan by the Moon, Dec. 12, 1738, p.m. observed in 

 Fleet-street with a reflecting Telescope of \5 Inches in Length. By Mr. G. 

 Graham, F. R. S. N° 459, p. 632. 



The occultation at 5^ 27"* & 



Emerged at 5 29 59 



Duration 1 2 53 



An Eclipse of the Sun, Dec. I9, 1739> in the Morning, observed by Mr. Short 

 in Surry-street, with a Reflecting Telescope of\6 Inches Focus, that magnified 

 about 40 times. N° 459, P- ^33. 



The beginning could not be seen for clouds about the horizon. About 35" 

 after 8 o'clock, there was an opening, when the sun seemed to be about 2 or 3 

 digits eclipsed. The end was exactly observed at 9*^ 1" 45% t. app. 



^n Eclipse of the Moon, Jan. 1, 1740, observed at Mr. Graham's house in Fleet- 

 street, by Mr. Short, with a reflecting Telescope ofQ Inches Focus, that mag- 

 nified about 40 times. N° 459, P- 633. 



Beginning about 8*" 25" 0' t. app. 



Beginning of total darkness at . . . 9 31 10 



End of total darkness 1 1 15 20 



End of the eclipse at 12 22 O 



But the beginning and end could not be distinctly seen for clouds. 



Some Remarks and Experiments concerning Electricity. By the Rev. J. T. De- 

 saguliers, LL. D., F. R. S. N° 459, p. 634. 



1. Bodies electric per se, are such in whom a virtue of attracting and repel- 

 ling small bodies at a distance is inherent, though it is not always in action, so 

 as to produce that effect. But by rubbing, patting with the hand, hammering, 

 warming, and sometimes only exposing to dry air, such bodies exert the virtue 

 above mentioned ; otherwise they are in a non-electric state. 



2. Non-electric bodies, are such in which no electrical virtue can be excited
