dauin, the editor of Cafar a ufum Del- 
point, imagines that this Amagetobria 
fxeuld be fought at Bingen, on the 
Rhine; and, in fapport of this opinion, 
he cites the verfes of Aufonius, in the 
beautiful defcriptioa of the Mofelle, given 
by that poct: 
*Peankerarm celerem nebulofo flumine Navam, 
Addita miratus veter} nova meniavico, - 
fEquavit Latias ubi quondam Gallia Cannas, 
M. d’Anville, with jutice, confidered 
this opinion as untenable, and Ceilarius 
was of the fame way of thinking. The 
refemblaace of the name of a place fitu- 
ated near the confuence of the Ogncn 
with the Saone, a little above Pontailler, 
and denominated /a Moize de Broie, to 
that of Admegetobria, led Chiflet to ima- 
ine that this might have been the fitu- 
ution of the torn mentioned by Czefar ; 
and this idea is approved by D’ ‘Auville, 
who oblerves, that this tradition is re- 
corded by Pierre de St. Julien, ia bis 4n- 
tiquities of the Burgundians. The extra-

advaniage of this opportunity to cleanle 
the bed of the Saone, which pailes by 
their town, found in it, among other mo- 
numents, the handle of an urn, on which 
is the name MAGETOB. This circum- 
ftance is confered as a proof that the 
town was not called Admageiobria, but 
Magetobria, or Magetobsiga- This was 
the opinion of Raymond Martin, who, 
ip his Alphabetical Explanation of the 
geographical fiimations a aaa in Cz- 
far, 2 be this town under the letter M, 
and calls it Magetobria. The prepcfi-

has lately asnounced a very curious pro- 
erty of the new earth called yttria.— 
When the muriate of yttria is heated to

muriatic acid ts treated in the fame wa

by Mefirs. HisinGer and Berzeiius,

M.Rosz has pubsifhied an account of white

A. fet of experiments on the folution of 
indigo in different kinds of fulphuric 
aciel has lately been laid before the public by 
M.Bucveiz, who found thatthe Britifh 
fulshuric acid was a bad folvent, unlefs 
it had been previoufly boiled with fulphur; 
that the acid manufactured in the North 
oi Europe diffolved it well in its natural 
fate ; but, when deprived of the fuiphu- 
rous acid gaz, it became as inefficacious as 
the Englifh. Hence it appears that the 
prefence of this gas premoted the folu-

it has long been known that the me-

‘may be employed to throw down copper,

Lead was precipiated in the metallic

The fame refult was obtained when zinc
