ru.wcE. — A rojiort on \\\f International Congress of Exporiniont Stations, liehl in 

 connoction with the Paris Exposition of 1889. has rocontly b«M»u issued by Messrs. L. 

 and H. Gran(h:iu. Besiih'S the jiroceedings of tlie conijre.ss the rejiort contains a 

 large amount of statistical information reg.irding the hist(uy, organization, work, 

 ^ndjiuhlications of the experiment statitms in France and other countries, and arti- 

 cles on .special suhjects in agricultural science. 



Brazil. — Dr. M. Gerlach, formerly assistant at the experiment Station in Halle. 

 Gernittny, has accepted a call from the Brai^ilian Government to establish in that

 proceed to Brazil immediately for that purpose. 



Tkstixg im.atinic cui.oKiiiK A.s TO ITKITV. — A. V. llolleuian (Chem. Ztg., 1892, 

 p. 3.">) ]toints out that while Kr.iuch's manual for testing cliemical reagents* retpiires 

 only that ])latinic chloride should dissolve to a clear sobition in alcolwd and leave a 

 residiu'. on evaporation, wholly insidiiblo in dilute nitric acid, these tests alone are 

 insutlicient to prove the jnirity of the reagent. He mentions having found snljihiiric 

 acid in jtlatinic chloride i)ut uj) by one of the Ijest-known (ierman manufacturers of 

 chemicals, and which the tests given by Kraucli indicated as pure. For use in (|uan- 

 titative potash determinations, according to the present nu'thods, it is essential that 

 the platinic chloride be absolutely free from this acid, for otherwise error may result 

 from the formation of barium sulphate, from the traces of barium in the solution, 

 along with the i)otassium-i>latinic chloridt> precipitate.
