 Japans meteorological system now comprises twenty-three observatories in the most important places throughout the country. From each district three weather reports daily are sent to the central observatory at Tokio, where they are prepared for publication by the lead ing journals of the seaports.
 With glass plates coated with suiphu- ret of calcium, Mons. Curtave Hermite obtains phosphorescent photographs. The exposure is made under a strong a5hs, and sae picture ;s ~ay aaiiss:s;sses aaiss:s;sses when the plate is taken into the dark.

 Oxygen Cheaply Lique6ed.-In note Q the French Academy of Sciences, Mons. Cailletet has communicated a plan Or producing liquid oxygen which is so 'imple that 1t is expected that the product nay soon become an article of com- nerce, as lique6ed carbonic acid now is n Germany. He states that when the Ias known as formene is slightly con- iensed and cooled in boiling ethylene inder atmospheric pressure, it is resolved nto an extremely volatile colorless fluid, md this fluid, in returning to a gaseous tate, yields degree of cold suf6cien, Q immediately iquely oxygen.
 Hot Yeark--Some interesting particu- ars concerning the historic hot seasons t Europe have been collected by an talian ssvaat. In 617 A.
