232 Opposition of Mars -d-ith the Sun. 



others were considerably reduced. The subject however de- 

 mands further illustration and inquiry; as it is one of consi- 

 derable importance when comparing the observations of dif- 

 ferent astronomers ; and even of different observers at the 

 same observatory. 



Besides a detail of these singular phenomena, the volume 

 contains, 1° a determination of the scale of the barometer used 

 at the observatory : 2° observations to determine the refrac- 

 tion near the horizon : 3° a new table of corrections for that 

 purpose : 4° the usual daily observations of the observatory ; 

 amongst which we observe the transits of those stars which are 

 pointed out by M. Schumacher as culminating about the 

 same time as the moon : and lastly above seven thousand addi- 

 tional stars, observed in zones, agreeably to the plan laid down 

 in the former volumes ; together with the elements for their 

 reduction. 



The present volume has reached this country much more 

 early (even by many months) than usual : it has in fact arrived 

 before the presentation copies intended for the public societies. 

 This unusual expedition must be attributed to the exertions 

 and activity of Mr. Bohte, bookseller, of York-street, Covent 

 Garden ; who is determined, as much as possible, to remove 

 the impediments which obstruct the early transmission of Ger- 

 man books to this country. 



M. PASQUICH AND M. KMETH. 



A scandalous attack has recently been made on M. Pas- 

 quich, the venerable director of the observatory of Buda, by 

 his assistant M. Kmeth ; and which has unfortunately been 

 circulated in many respectable journals. The latter accuses 

 the former of having forged the observations of the observa- 

 tory : that is, in fact, of giving to the world a statement of ob- 

 servations that were never made. Some of the principal as- 

 tronomers on the continent have taken up the subject, in 

 order to convince the world of the innocence of M. Pasquich. 

 Amongst those who have come forward on this laudable oc- 

 casion are MM. Gauss, Olbers, Bessel, Encke and Schu- 

 macher.

OPPOSITION OF MAKS WITH THE SUN. 



Gosport, March 35th, 1824. 

 As the announcement of the opposition of Mars must have 

 excited some curiosity among our astronomers, and as cor-
