l.cpine. — On the integration of Hamilton's differential 



by M. I'aul Slaeckel. Concerning the results shown 



■ r. the author remarks : " There is the true general- 



i.iouville's theorem, which allows the utilisation of 



-- in the integration of Hamilton's equations to find 



new iyi>es of integrable equations, that is, to form new linear 



elements of which the geodesic lines can be determined." — On 



parasitic electrodes, by -M. Ci. Delvale/. — On the mechanical 



properties of alloys of copper and zinc, by M. lleorges Charpy. 



The tensile strength increases with the percentage of zinc, 



attains a maximum at 43 per cent., and then decre.ises rapidly ; 



the elongation before rupture al.so increases with the 



zinc, passes through a maximum at 30 per cent., and then 



rapidly diminishes. — On a carbide of glucinum, by M. 



P. Lcbeau. Pure crjslallised glucinum carbide has been 



prepared at the high temperature of the electric furnace. 



The properties of this carbide, more (Mrticularly its reaction 



with water resulting in its decomposition in the cold with the 



prtKluclion of methane, resemble those of aluminium carbide 



Cj.Mj, hence support isgiven to the formula C:,Be4. The atomic 



weight of glucinum must be near 14, and glucina becomes
