 pie* of this work to all his friends in England ex- 

 cept Dr Hooke ; who, in revenge of the affront, pub- 

 lished in 1671 hi* " Animadversion* on the First 

 Part of the MaMa Celtttit, of the honourable, 

 learned, and famous Joanne* Hevelius, together with 

 an explication of aiHisf instrument* lajaiie by R. ri. 

 Land. Ho. Thi* work wa* characterised by the ir- 



^of it* author. It wa* written with that 

 arrogant superiority, which injured his own 

 and excited toe highest resentment on the part 

 In the same year, Hevelius *ent a letter 

 to the Royal Society, containing a reply to the objection* 

 of Hooke and Flanutead, and appealing to observation 

 for the correctness of his opinion*. He complained of 

 the " bitterness and boasting" with which he had been 

 attacked, and requested that the Royal Society would 



Tand Dr Halley*, who held 



nearly the same opinion* a* Hooke, was requested to 

 repair to Dantsic. He arrived in that city on the 96th 

 May 1079, and continued with Hereiius till the l-tli 

 of July. By mean* of -a good instrument, furnished 

 with telescopic sights, Hafley compared hi* own obser- 

 vations with those of Hevehu* ; and he particularly at- 

 tended to the Mxxeasive observations njanV anon' the 

 same stars by Heveliu*. wrth hi* '

Hevelius had fortunately presented about 30 o 

 of this work to his friends; for before it was published, 

 his property of every description was consumed by a 

 dreadful lire, on the 26th September 1(>7<>. No fewer 

 than teven houses, containing his money, plate, gold, 

 silver, household goods, printing houses, great part of 

 his library, the remaining copies of all hi* printed 

 work*, published at his own expcnce, from the year 

 1647 to 1679, and particularly liis observatory, with 

 all his optical and astronomical instruments, were com- 

 pletely reduced to ashes Among the articles preserved 

 were the Utter part of his Macfitna Ceirdu, containing 

 the observation* of nearly 50 yean, and his tfen Ca- 

 talogs aftkt Fixed Start. 



A rullaccount of this calamity, and of his dispute 

 with Dr Hooke, were published in 1<>8.5, in his " An- 

 nu* Climactericus, sive rerum Uranicarum et obscrva- 

 tionum annus quadragesimus nonus, exhibens divenas

Thi* work was the last which Heveliu* published. 

 Worn out with the infirmities of age, and with the la- 

 bours of (cience, he died on the 28th January 1687, in 

 the 7'>lh year of hi* age. Hcveliu* IrA behind him the 

 ftuwUtiao of having been one of the most industriu< 

 and ingenious practical astronomer* of the age in v 

 he lived The surpriae which Halley expressed at the 

 large bra** sextant, wonderful accuracy of his observations, must be 

 hiarnly favourable to by every peraon who examine* them, and who consi- 

 n, dated July 8- 1 8th, ders that they are well made by unassisted vision, and 

 that the instrument* were constructed and graduated 

 with hi* own hand*. 



Hevelius left behind him two complete works, and 

 other manuscript*. The first of these nun
