6th, and 7th. Hoar only on the 11th. On the 14th and 15th frost, but of 

 the above degree only: a little sleet on the 31st post meridian. To the 22d no 

 frost or snow. On these coldest days the thermometer was never so low as 38°, 

 but on 3 days only, viz. Dec. 14th and 15th, and Jan. Qth. It will appear that 

 our cold was nowise excessiv^e, when it is considered that the balm of Gilead, in 

 the natural open ground, has not suffered: the myrtles are in perfect health; the 

 mignonettes in flower; the cluster rose and white violet in bloom at Christmas; 

 and the scarlet double ranunculus is full blown; the double hyacinths have formed 

 their bells, and some are now ready to unfold. The whole quantity of rain fallen 

 in 1762 was 29-tV inches. 



Fill. A Delineation of the Transit of Venus expected in the Year 17 69. By 



Mr. James Ferguson, p. 30. 



Besides the delineation, Mr. F. points out some places that might be very 

 proper situations for observing that transit, viz, Wardhuys in Norwegian Lap- 

 land, and the Solomon isles in the great South Sea; or that any other place near 

 the north cape will be just as well for the northern observers; and Tuberon's 

 isle, or St. Bernard's, or the Fly islands, in the great South Sea, will answer as 

 well for the southern. 



IX. An Account of an Appulse of the Moon to the Vianet Jupiter, observed at 



Chelsea. By Mr. Samuel Dunn. p. 31. . 

 The alteration of the angles of position made by the cusps of the moon, and 

 a planet to which the moon makes a near appulse, will always enable those astro- 

 nomically inclined to determine from observation, the longitudes of places, by 

 the naked eye, and a clock or watch set to apparent or equal time. Such an ob- 

 servation Mr. D. made at Chelsea, Dec. 25, 1762, at 1 1^ 0"^ 30* apparent time. 

 Jupiter's distance from the moon half a degree, when in the line of the moon's 

 cusps. Lat. 51° 29' 5", Long. 41'^ west of Greenwich. 



X. A Catalogue of the Fifty Plants from Chelsea Garden, presented to the 

 Royal Society by the Company of Apothecaries, for the Year 1762, pursuant 

 to the Direction of Sir Hans Sloane, Bart. By John Wilmer, M. D. p. 32. 

 This is the 41st presentation of this kind, completing to the number of 2050 



different plants. 



XI. Observations made by Mr. John Bartram, at Pennsylvania, on the Yellowish 



fVasp* of that Country, p. 37- 



Mr. B. saw several of these wasps flying about a heap of sandy loam ; they 

 settled on it, and very nimbly scratched away the sand with their fore feet, to
