New Binocular. — Beck has produced a portable binocu-

 as to remove the stage entirely from the stand for con- 

 venience in packing. The stand is large, fitted with a 

 centering apparatus and suitable for pond work. 



A New Station. — A biological station containing aquaria, 

 laboratories, rooms for collections and library is in course 

 of erection near Sebastopol, on the Black Sea. It is ex- 

 pected that the building will be opened for scientific work 

 during the present year. 



Mountains, — At an altitude of 2,000 feet a search for 

 microbes proved fruitless in Switzerland and presumably 

 would elsewhere. 



^A^olmer Forest. — The Guilford Natural History and 

 Microscopical Society has succeeded in securing the pro- 

 tection of birds, foxes, etc. in this forest. 



Carbondioxide Crystals. — When solid carbondioxide is 

 examined under the microscope, wire-like crystals may be 

 seen along its edges. Branching filaments issue from 

 them apparently at right angles and somewhat resemble 

 the groups of minute crystals seen in crystallised iron, 

 gold and ammonium cloride.
