466 THIRD REPORT — \83o. 



the time of Mrs. Flamsteed's deatli, which took place on July 

 29th, 1730. 



Here the correspondence ceases, probably on account of the 

 circumstances mentioned in the last letter, whereby it appears 

 that jNIrs. Flamsteed did not leave either Mr. Sharp or Mr. 

 Crosthwait a single farthing for all their services ; neither had 

 they received any remuneration since Mr. Flamsteed's death 

 for their unparalleled exertions in her behalf. 



*^*' Since the above statement was written, Mr. Baily has 

 discovered amongst Flamsteed's manuscript papers, deposited 

 at the Royal Observatory at Greenwich, all the Answers of Mr. 

 Sharp to the above letters of Flamsteed; thus constituting a 

 complete correspondence between the parties fornearly eighteen 

 years. 



CORRIGENDUM IN PROFESSOR POWELL'S PAPER.

 Powell's paper a formula is introduced (p. 377) which the author finds, since 

 the paper was printed, is incorrect ; this however does not affect the rest of the 

 paper : but the whole will shortly appear in detail in another form.
