appear extraordinarv, that vaccination, lliongh so generally 

 successful, should sonielinics fail of rendering the humaa 

 constitution unsusceptible of small-pox, especially since it 

 has been found that in several instances sniall-pox has oc- 

 curred to individuals over whom the sniall-pox inoculation 

 had appeared to have produced its full inHuenee. Three 

 instances of this kind have taken place within the last 

 month, and in another instance the natural small-pox has

A NEW COMET. 



X HE last French paper? contain llic following account 

 civen bv the astronomer Bouvard, and dated from the Im- 

 perial Observatory, August 21 : — "The comet discovered 

 at Viviers, on the £5th of last March, by M.dc Flauguergurs, 

 and seen till the end of May, when it ceased to be visible, 

 in consequence of its proximity to the Sun, has again ap- 

 peared this morning in the constellation of the Little Lion, 

 its motion, almost entirely in declination, carries it towards 

 the north, close to the constellation of the Great Bear, where 

 it will then be visible every night, even to the naked eye. 

 This morning, between three and four o'clock, I discovered 

 this comet very near the horizon ; its position was nearly 

 that laid down in the elements calculated by M. Burckhardt; 

 and according to my observations, I have determined it as 

 follows: — Right ascension, 147 deg. iSmin.; North decli- 

 nation, 32 deg. 53 min." 



The following is a letter from Dr. Olbers, of Bremen, to 

 Prof. Boden, on the same subject : — " The comet which 

 M. Flauguergues discovered on the C5th of March at Viviers, 

 and M. Pons on the 1 1th of April at Marseilles, and which 

 was seen on the 20Lh of May at Paris, will re-appear before 

 the end of August. It will be much more visible then than 

 in the spring. Its greatest brilliancy will be in October, 

 and' it may be visible still in December. In September and 

 October it does not quit with us the southern part of the 

 lieaven."
