4S6 Additional Notes. 



P. S. [Bj/ the Editors of the Magazine.] It is easy to 

 see, by a careful perusal of these two letters, ami that in our 

 last Magazine, the progress of this invention, and how far 

 Mr. Godfrey ought to be considered as the inventor. It is 

 our business to give impartial accounts of facts and transcripts 

 of authentic papers. The reader, after that, is to judge for 

 himself. For our own part, we have no hesitation in pro- 

 nouncing Mr. Godfrey the real original inventor of this 

 famous and useful instrument. 



The following extract of a letter from Mr. Hazard, which 

 accompanied the above documents, ought to be added, in 

 justice both to the Royal Society and to Mr. Godfrey. 



" Alderman Hillegas, of this city, (Philadelphia) knew 

 Godfrey. He says he remembers to have heard, perhaps 

 SO years ago, that, as Hadley had obtained the patent, com- 

 plete Justice could not be done to Godfrey; but that the 

 Royal Society, thinking his ingenuity ought to be rewarded, 

 either subscribed for him as individuals, or gave him out of 

 their funds, c£ 200 sterling: and knowing his infirmity (for 

 it seems he was apt to indulge in intemperate drinking), they 

 thought it better to send the amount in household furniture 

 than in cash, ^nd, inta^ alia, sent him a dock; which the 

 Alderman remembers to have seen." 



Godfrey had a son, Thomas Godfrey, jun. who, in 

 1765, published a volume of Juvenile Poems. The young 

 man is spoken of, by the writer of the preface, as possessing 

 great natural endowments, with but little cultivation; and as 

 deserving to be ranked, as well as his father, among the cu- 

 riosities of Pennsylvania. — MS. Letter oj the Rev. Dr. Eliot, 

 of Boston, to the Author. 



It is worthy of notice, that the use of the Quadrant m 

 question was confined to the English nation until the year 

 1736, when M. D'Apres de Mannevillette, the great 

 maritime Geographer, employed it on board a French ship; 

 and on his return to France, one of the earliest objects of his 

 attention was to state, in a public print, his high estimation of 

 this curious instrument. He thus had the honour of intro- 

 ducing to his countrymen one of the most valuable inventions 

 of the age.
