the celeftial bears under ihe name of Mothers. Bui it ap- 

 pears doubtful whether the mother goddefles of the Gaul's of 

 Britain, Germany, Spain, &c. were the fame diities. ll is 

 at lead certain that in conCequence of migrations, the notions 

 refpecting thefe goddeffes. their fun£lions and attributes, had 

 at that lime been ftrangclv altered. The figures given bv 

 Montfaucon hold children in their arms, Tike the fcmile 

 figures fcen on medals of fome of the cmprcircs, with the 

 legend Juno Lucinu; which confirms the opinion of C. 

 Mongez, that thefe figures reprcfcnt the mother goddefles in 

 general, and in particular the Junos and Genii of women. 



PALLADIUM, OR NEW SILVER. 



We have juft been favoured with a fpecimen of a metal, 

 faid to be a new one, to which the above name has been 

 given, and which, anvuig others, is faid to poflefs the fol- 

 lowing properties: — i. It dilfolves in pure fpirit of nitre, and 

 makes a dark red folution. 2. Green vitriol throws it down 

 in a (late of a reguius from this folution, as it alwavs does 

 gold from aqua reg'ia. 3. If you evaporate the folution you 

 get a red calx, that dilfolves in fpirit of fait or other acids. 

 4. It is thrown down by quickfilver, and by all the metals 

 but gold, platina, and filver. 5. Its fpecilic gravity by ham- 

 mering was only 11-3; but by flatting, as much as ii-8. 

 6. In a common fire it larniflies a little, and turns blue; 

 but comes bright again, like other noble metals, when 

 ftronger heated. 7. The greatcft heat of a blackfmilh's fire 

 would hardly melt it. 8 ^But if you t mch it while hot with 

 a fuKdl bit of fulphur, it runs as eafily as zinc. — It is fold 

 only by Mr. Forlter, at No. 25, Gerrard-ftrect, Soho, Lon- 

 don, in famples of five fliillings, half a guinea, and one guinea 

 each. — VV^e have not had lime to fubjcft the fpecimen lent 

 'to us to any chemical lefts. When we do, we fliall report the 

 refult to our readers. Where or how it has been procured 

 ue have n l yet learnt. 



IMPROVED LAMPS. 



Mr. Paul, of Geneva, now in London, has made fome im- 

 portant improvements in the conftrudion of lamps and re- 

 tleitors, by which, among other advantages, that liszht whicii 

 is ufually thrown up into the atmofphere and lo(i, ili reflecJ-ted 

 to the fj)ace intended to be illnminaled ; by which a much 

 greater etfeil is produced, and at the fame time a laving in 

 ■ tlie confumption of the oil. We underitand thev are foon to 

 be cmjiloycd by Mr. Smelhurd in lighting the llreets.
