boiling point is constant, and then to distil it from oxide of lead j 

 by these means a limpid colourless liquid of a sharp and burning 

 taste is obtained, and a smell which resembles that of benzoic 

 aether. It burns with a yellow flame, is oily to the touch, boils at 

 317° Fahrenheit, and its specific gravity is 1-036.

This aether when treated with potash yields alcohol ; when sub- 

 mitted to the action of chlorine, succinic aether is decomposed ; 

 in diffused light the reaction goes on very slowly, but solar light 

 immediately determines it. The chlorine disappears, and is re- 

 placed by muriatic acid : there are very soon deposited upon the 

 sides of the bottle numerous crystals of succinic acid, mixed with 

 a viscid yellow matter. 



Ammoniacal gas has no action upon it ; but when shaken with 

 liquid ammonia, the succinic acid soon disappears, and after some 

 hours a white crystalline matter is precipitated, which appears to 

 have some analogy with oxamithon. 



The density of the vapour of succinic aether is 622; calculated 

 according to its formula, we have

Succinamide. When ammoniacal gas is heated and made to act 

 upon succinic acid, a perfectly white substance is obtained ; not 

 possessing any of the properties of the acid, crystallizing with great 

 readiness in very regular rhombs, and more soluble in alcohol than 

 in water. When treated with potash at a high temperature it 

 loses its ammonia. When succinate of lime is submitted to heat, a 

 substance is obtained which M. Darcet calls succinone. — Journal de

NEW LOCALITY OF PLENAKITE. 



Plenakite has been found in very perfect crystals, accompanied 

 by quartz, in the brown iron ore of Framont. Its specific gravity 

 is 300. Hardness equal to that of topaz. It cleaves readily pa- 

 rallel to the faces of a rhombohedron of 116° 40', according to 

 M. Beirich. It has been analysed by Prof. G. Bischof of Bonn, 

 who finds that its composition is expressed by the formula
