 The boiling points of potassium and sodium have been satisfactorily determined by English phys icist by placing the metals in 6 hollow iron ball with blow-pipeS An air thermometer was low cred into the vapor cf the boiling metal, scaled, and broken open under water, the temperature being then calculated from the volume of water forced into the bulb. The mean results gave TAP deg. c. q ,s6s deg F.) as the boiling point of sodium, and 667 deg. Q,2Ss deg) that of potas- sium.
 COVERED RrvERs.-An apparent disappearance is 2 phenomenon that seems to have taken place with some rivers. Captain John Page, of the Argen- tine navy, mentions that the upper Paraguay, if absolutely lost for many miles has been known to How beneath . matted covering of living and dead vegetation several feet in depth. In the year 1858 one of these growths, under the influence of ex- traordinary inundation, broke loose and drifted two thousand miles, bringing up at Buenos Ayrss with many animals and reptiles that had taken refuge upon 1t.
 SCIENTIFIC FARMNG.-The first agricultural experiment station, according to Prof ". O. Atwater, of the United States department-of agri- culture, established at little German village near Leipzig, in 1851. Tn 1856 there were i've, h 1861 fifteen, in 1866 thirty, and to-day there are more than one hundred experiment stations and kindred institutions in the different countries of Ecrope. The movement is extending to Asia and to South America The first agricultural experi- ment station In America was established ct Mid- lefoun Conu Tn fha chauaf~al Iahor~forw Waa-
