A full account of this calamity, and of his dispute with Dr Hooke, were published in 1685, in his " Annus Cli• mactericus, sive rerutn Uranicarum et observation= annus quadragesirnus nonus, exhibens diversas occulta tiones tam planetarum quam fixarum, post editam Machi nam Celestem observatas, necnon plurimas altitudines meridianas sous, et distantias planetarum fixarumque, eo army impetratas cum amicorum nonullorum epistolic ad rem istam speetantibus et continuatione historic DOV22 stellar in Cello Ceti, ut et annotationum reruns celestium." This work was the last which Hevelius published. Worn out with the infirmities of age, and with the labours of science, he died on the 28th January 1687, in the 76th year of his age. Hevelius left behind hint the reputation of having been one of the most industrious and .ingenious practical astronomers of the age in which he lived. The surprise which Halley expressed at the wonderful accu racy of his observations, must be felt by every person who examines them, and who considers that they are well made by unassisted vision, and that the instruments were constructed and graduated with his own hands.

Hevelius left behind him two complete works, and many other manuscripts. The first of these made its appearance in 1690, in folio, entitled " Prodrornus astronomix, exhi bens fundaments qux tam ad novum plane et correctiorcm stellarum fixartun catalogum construendum quam ad om nium planetarum tabulas corrigendas omnimodespectant, necnon novas et correctiores tabulas solaces, aliasque plurimas ad astronomiam pertinentes, utpote refractionum solarium, parallaxium, declinationum, angulorum eclip ilex et meridiani, ascension= rectarum et obliquarum horizonti Gedanensi inscrvientium, differentiarum ascen sionalium, motus item et refractionum stellarum fixarum, quibus additus est uterque catulogus stellarum fixarum, tam major ad ann. 1660, quam minor ad ann. completum 1700. Accessit Corollarii loco tabula motus lunge libra torii, ad bina sxcula proxime ventura prolongata, brevi cum descriptione ejusque usu."

This work, which was published by his widow, contains the catalogue of 1888 stars. It was afterwards reprinted in the 3d vol. of Fiamstead's Historia Celestis, and is in corporated in the catalogue of stars given in our article ASTRONOMY.

In the same year appeared his other posthumous work, entitled Firmamentum Sobiescianum sive Uranographia, totum ccelum stellatum, utpote tarn quodlibct sidus quam 0111HCS et singular stellas, secundum genuinas carum inag nitudines nude) oculo ct olim jam cognitas, et imper pri mum cletectas, accuratissimisque organic rite observatas, exhibens ; et quidem quodvis shins in pcculiari tabella, in piano descriptum, sic ut ornnia conjunctim totum globum cclestem exactissime refcrant : grout ex hinis berrispheriis rnajoribus, borcali scilicet et australi, adhuc clarius cuique patet." This work contains 54 charts, representing the whole heavens.

I levelius was elected a Fellow of the Royal Society of London in 1664, and contributed several papers to the Philosophical Transactions.

When M. Delisle passed through Dantzic on his way to Russia in 1626, he purchased all the manuscript obser vations of Ilevelius, along with his extensive correspon dence, forming seventeen folio volumes, four of which were occupied with his observations. These manuscripts contain much curious information respecting the history of astronomy. They were lodged by Dclisle in the depot of of the marine at Paris. Those who wish for farther and more minute details respecting the life and writings of Hevelius, will find much information in a life of him, pub lished at Dantzic in 1780 by Benjamin Leugnich, and en titled, Hevelius, oder 4nekdoten and Xachrichten von diesem beruehmten Mamie. Many particulars respecting our author will also be found iu Bernoulli's Travels in Prussia, Poland, and 1Viirsovia, 1782, p. 183. A figure of his mausoleum is given in Bernoulli's Collection of Voyages, torn. ii. 1781. See also the Journal de Savans, flout, 1782, and Mures Journal Literaire, Nuremb.
