this uniform is extencl,cd to the president, the academicians 

 and adjuncts, and also to the pupils ; but with this differ- 

 ence, Uiat, besides on the collar and facings, they have em-

M. Gorachow, a merchant of Jakusk, has transmitted to 

 his imperial majesty a horn of extraordinary size, which was 

 found m the river Krom. This rarity has been sent to the aca- 

 demy of sciences, to be preserved in its museum. It is 

 worthy of remark, that the inhabitants of the district 

 where this horn was found beheve it to be the claw of a 

 bird called Kosroskari.

ANTIQUITIES. 



Baron D'x\ketin, librarian to the elector of Bavaria at 

 Munich, has made a very curious discovery in the centralli- 

 brary of that city : it is an old manuscript of the thirteenth 

 century, containing a treatise on the Greek firej which not 

 only gives an acc-nuit of the method of preparing it, sup- 

 posed"by the learned to be lost, but also a process for making 

 gun-powder similar to that followed at present. 



NEW VEGETABLE ACID. 



M. Klaproth, in Scherer's Journal of Chemistry, has? 

 given a paper on the naaire of a saline substance observed 

 and collected in the botanical garden of Palermo, by Mr. 

 Thomson, on the bark of the white mulberry tree {Moms 

 alba) . 



This matter was of a brownish colour; it covered and 

 even pepetrated the bark. Its taste was nearly similar to 

 that of the succinic acid. On coals it swelled up slightly 

 and burned, leaving an earthy residuum. A thousand part'? 

 ■of water dissolved thirty-live parts of this salt warm, and 

 fifteen cold. By evaporation it gave crystals in needles 

 united in a radiated form, and of a pale woad colour. 



Barytes formed no precipitate in the solution of this salt. 



Alkaline carbonates occasioned in it a brown deposit, 

 which by calcination passed to white, and then dissolved 

 with effervescence in nitric acid. The sulphuric and oxalic 

 acids occasioned in a nitric solution of it precipitates, which 

 indicated the presence of lime,
