■ ** Thcfc elements will corrcTpond to three obfervatlons, of 

 the 29th March, 7th and 16th April. I have omitted^ no- 

 thing that coutd render this calculation as exad as polhble; 

 but "the liolioccntric arc being only tour degrees, we can 

 expect only to attain ncarlv to exadnel's. Trie ohCervation, 

 therefore, of April 9, which Mechain was fo kuid as to 

 communicate to me, gives an error in longitude of— 35", and 

 in latitude of — n ". I am, however, far from wiiliing to 

 exclude elliptic orbits, and I (hall continue my rcfearches 

 with them in proportion as a greater number of obfcrvations 

 are obtained ; but, in the mean time, I was defirous to gra- 

 tify the curiofity which the polhbility of another new planet 

 fecms to fiave excited in the public.

METEOROLOGY. 



At Derbv, an uncommon pha^nomenon appeared in the 

 air a few mornings ago : it confilted of four circles, and 

 part of another, in the following order : — The fmalleft, which 

 was nearell to the fun, might l)e tifieen degrees diameter, with 

 luminous fpots to the right and left, like what are called para- 

 helia; the fecond encompafled the former, and was twice as 

 large; the third the fize of tlte fecond, anu joined its cir- 

 cumference 10 the weft; and the fourth circunjf.ribed all the 

 others, and was touched upon the wcllern fide by part of an- 

 other of the fame diameter. 



VACCIxVE IXOCULATION. 



This ufeful pra6lice fcems to be gaining ground in Spain. 

 Dr. Francifco Figuillcm has puhlillied the following work in 

 recommendation of it: — Lc f^acuna en Effayia, CartiisFa-

 Madrid, 8vo. In Catalonia, above 7000 perfons were ino- 

 culated between the month of December ' 800, and Sep- 

 tember 180 . " On the highed mountains and amld(l the 

 fevtrcft cold, in the decpclt valleys and amidfl the greateft 

 heat, (fays the letter from which this account was taken,) 

 the inoculation has been attended with complete lucccfs." 



A letter from Portugal to Dr. Alibert at Paris, after men- 

 tioning the oppofition which has hitherto been made to the 

 vaccine inoculation in that country, fays, — " Some one has 

 found here, in a Porluguefe work, that the vaccine inocula-
