Some further Remarks on P. Soiiciefs Dissertations against Sir Isaac Newton. t 

 Chronology. f By Edmund Halley, LL. D. N° 399, p. 296. 



When I gave my remarks on P. Souciet's Dissertations against Sir Isaac 

 Newton's Chronology, I was obliged to take what he was pleased to give us out 

 of Hipparchus's comment on Aratus, not having then that author himself by 

 me. Since then, having procured the Florence edition of Hipparchus, anno 

 1567, I find an argument very much ad hominem, which the R. P. must con- 

 fess will bring the Argonautic expedition full as low as Sir Isaac Newton 

 makes it. 



P. Souciet, in his 5th Dissertation, p. II9, 120, finds out a star of the first 

 magnitude, closely adjoining to that we now call the first star of Aries, as it is in 

 the catalogue of Ptolemy, where it is said to be in the horn of Aries, and not 

 in the ear. This star the R. P. supposes long since to have disappeared ; but 

 that being of old very considerable, it was from this first star of Aries, the 

 zodiac began, though for argument-sake he is contented to let it begin as Sir 

 Isaac does, with the aforesaid star in the ear or horn ; which Hipparchus, in 



* We shall only remark, that although the work is entitled Vegetable Statics, yet in the 6th chap, 

 the author gives an account of a vast variety of experiments relative to the disengagement of air (by 

 distillation, fermentation, chemical solution, &c.) from animal and mineral, as well as vegetable 

 bodies. Also, of the absorption of air in the burning of sulphur, and phosphorus, and in the process 

 of respiration ; so that this chap, contains the rudiments or germs of some of the most brilliant dis- 

 coveries (particularly of those which relate to the constitution of the atmosphere and to gaseous 

 chemistry) which subsequent philosophers have made.
