Phosphoric acid 15-01 13*52 14*40 



Oxide of uranium 58-45 5720 60-80 



Oxide of copper 8-27 



Water 15*22 15-55 



Silica 0-49 



Earthy matter 0*61 0'22 



The formula deduced from these analyses is 



[P 2 O 5 , Cu 2 O, 2U 2 O 2 O + 8 aq] . 

 The uranite of Autun gave the following results : — 



Phosphoric acid 14*00 



Oxide of uranium 63 - 28 



Lame 5*86 



Barytes 1*03 



Water 14*30 



Uranite has therefore a composition similar to that of chalkolite, 

 its formula being [P~ O 5 , Ca 2 O, 2U 2 O 2 + 8 aq]. It is to be ob- 

 served that the formula long since proposed by M. Berzelius agrees 

 exactly with that of M. Werther. 



M. Werther obtained chalkolite artificially by the following pro- 

 cess :— He took the salt of uranium [P 2 0\ H 2 O, 2U 2 O 2 + 8 aq], 

 and boiled it for some time with a solution of subacetate of copper, 

 decanted the liquid, digested the residue with acetic acid, and washed 

 it perfectly : he thus obtained a greenish powder, which presented 

 by the microscope the unaltered crystals of the phosphate of uranium 

 which he had employed. This product contained 146 per cent, of 

 water, and 8*7 per cent, of oxide of copper. — Journ. de Ph. et de Ch.,

SOCIETY OF THE FRIENDS OF THE NATURAL SCIENCES OF 

 VIENNA. 



The Wiener Zeitung of the 28th September last contains a report 

 of the proceedings of a Meeting held at the Imperial Mint of Vienna, 

 on the 22nd of the same month, at which Bergrath Haidinger pre- 

 sided. 



The President communicated to the Meeting that his application 

 to the Government respecting the formation of a Society of the 

 Natural Sciences had received the following favourable answer : — 

 " According to an announcement made by the Minister of the In- 

 terior on the 22nd of July of the present year, His Majesty the 

 Emperor and King, by a Decree of the 18th of July, has been gra- 

 ciously pleased to sanction the formation of the Society proposed by 

 you, under the appellation of The Society of the Friends of the Na- 

 tural Sciences of Vienna (Gesellschaft der Freunde der Naturwissen- 

 schaften in Wien)." Circumstances inevitably resulting from the 

 existing state of affairs, and the summer-months during which so 

 many scientific men and others interested are absent from the ca- 

 pital, render it unavoidable to postpone for a time the General 

 Meeting which is necessary to be held for the formal constitution 

 of the Society. Notice of this Meeting will be duly given. 



This communication was preceded by several others of a scientific
