cerning the phoenix; Pliny fpeaks of its 

 repioduftion; Tacitus informs us, tliat it 

 repairs to Heliopolig to die. It was con- 

 fecrated to the Sun. "One of the times of 

 its appearance occurred during the reign 

 of Sefoftris, 1318 years before our era.— 

 Horus Apollo and Nonnus, affert that it 

 was an eijibkm of the Sun, and one of 

 the names of that luminary. 



In a Medical Thefis M. BcuUt had 

 railed doubts concerning the age of Hip 



gafcar and the Eaft Indies, a vocabulary 

 cf Madagafcar, aftronomical tables to 

 find the longitudes at fea ; in three vo- 

 lumes o£^avo. We have alfo to ani.ounce 

 two other works on Africa : " Hilioiical 

 Account of the Diicoveries and Settle- 

 ments of the Europeans in the North and 

 Weit of Africa, till ths commencement 

 of the 19th century ;" to which are an- 

 nexed, Horn-niann's Travels inro Fezzan, 

 and all the accounts obtained by the Afri- 



pocrates, in confequenre of a paflage of can Society relative to the empires of Bor- 



that author on the rifing of Ariiurus ; 

 but M. Dupuis has remarked, that a 

 fingle obl'i.rvition is fufficient to dtllroy 

 the whole theory if M. Boulet, who af- 

 ierts, that the rifing of Arftu'us is an 

 heliacal rifin?, again i (he ex/refs text of 

 Hefiod, who ftys, that it is a riling of the 

 the twilight which t >kes place at the dole 

 of day, at the beginning of tne night. — 

 If it were true, as he maintains, that the 

 colures of the equinoxes ought to be 

 placed fo as they mu.1 have been three 

 tlicifand ye^rs ago, f'l far from findmg 

 that their pofi ions currefpond with thofe 

 ftated by Heliod, wefhould fee that Siiius 

 was not vifibl- und r ihe parallel of 39 

 degrees, and the o her appearances would 

 not have happened at the period indica-ed 

 by Heiiod. So great ■* change in the de- 

 .clinarion would thence refult, that the 

 ridngs and fettins^s would no longer cor- 

 relpond to the periods ot the year to 

 which the author has relene 1 them. 



Geograph^' has likewiCe madelbmepro- 

 grci^. A Map of H.'Uand is preparing 

 in tr.at countrv with infinite pains : the 

 fame iirecautions are oV)ferved as if the 

 point ill quellion was tlie menfuration of a 

 degree. M. tie Z ich has given in his 

 Journal the Chat' ot \\\t triangles which 

 are already finilh-d ; they adjoin to thofe 

 meafured oy M. De'ambie for the great 

 meridian; and the ililtaice between Dun- 

 kiik;ind M'^ntcallel is taken for the firft 

 fide. When the Triangle!, are completed, 

 abafe will l)e meaiured towards the north 

 for the purpofe cf verifying them. The 

 Batavian Republic has charged Colonel 

 Krayenhoff with the fuperintendance of 

 this new map. 



M.Rochon, who in the third volume of 

 hU Voyages gave an eafy method tor re- 

 ducing the di(iancc:> obferved at fca, has 

 this year procured a curious inftrument to 

 be made for Hill farihir facilitating ihofe 

 calculations. He has likcwil'e puhliflied 

 an important work intitled " Voyage to 

 Madagafcar, to Morocco, and the Indian 

 8eas," accompanied with maps of Mada-

A very beautiful HyJrographical Chart 

 of the White Sea appeared in the month 

 of November at Peterfturg. The author 

 is Lieu'enantOeneral Kutufoff. Several 

 naval officers have been employed tour 

 years under his direction in collecting the 

 materials necefiary to the compofition of 

 this chart. The coads of the White Sea, 

 of its gulfs, and of part of the Frozen 

 Ocean, are drawn from trigonometrical 

 furveys ; its depth has been meafured 

 with care, and fixteen of the principal 

 point's of the coalf have been determined 

 by ;iiu-onornical obfervations. 



In America, Captain Lewis has under- 

 taken to afcend tiie .MilTouri in quill of a 

 psffage to the Wellern Ocean. 



.M. Lnrtique, who has for thirty years 

 been attaclied to the depot of the navy, 

 has completed a large and beautiful Map 

 of America in relievo, exhibiting the 

 mnurtainsand iflands, anl the colours of 

 the fea, in I'uch a manner as cannot fail to 

 interefV all thofe who (ludy geography : 

 even i he blind may learn that Icience from it. 

 M. Coulomb has n ad an inteielling 

 Memoir on the effcft of heat 011 magnrt- 

 ifm. At *oo degrees of heat it lo;ts |, 

 and the whole at 700 degrees, at whictJ 

 the tempering of ftcel < nly commences. 



To alceitain thofe elevated degrees 

 which the thermometer cannot indicate, 

 M. Coulomb puts a pound of ignited 

 iron into a pound of water, the heat di- 

 vules itfclf between the ftrel and the w»- 

 fcr, and you perceive the relation of the 

 caloric to the two lubltanccs ; the water 

 changes nine times lei's than the iron ; it 

 requires nine times the heat to raife water 

 to a certain temperature than iron.
