with ether. These crystals are larger than those of the neutral 

 salt, and retain their acid after several solutions and crystalli- 

 zations. An analysis of the neutral salt gave — 



Sulphuric acid 8.84 9.697 



Brucine 91.16 100. 



The sulphate of strychnine and morphiura are composed as 

 follows : . 

 Sulphate of strychnine, sulphuric acid.. 



Sulphate of morphium, sulphuric acid . 



The muriate of brucine is easily obtained in quadrangular 

 prisms, terminated by oblique faces. They are unalterable in 

 the air, and very soluble in water ; if heated, at a certain point 

 they decompose, and the muriatic acid escapes in white vapours. 

 It is decomposed by sulphuric acid, and by those bases 

 which decompose the sulphate. When analyzed it gave — 



Brucine 94.0467 100. 



Muriatic acid 5.9533 6.331 



agreeing extremely well with the calculations made of its com- 

 position.

These also agree pretty nearly with the calculations. 



The neutral phosphate of brucine is soluble uncrystaUizable 

 Kalt. When more acid is added, the supersalt formed, crystal- 

 lizes readily, and forms large rectangular tables. It is very 

 soluble in water, effloresces slightly in the air, and is soluble in 

 strong alcohol at common temperatures. 



The neutral nitrate of brucine does not crystallize, but forms 

 a gummy mass by evaporation, but, on the contrary, the super- 

 salt crystallizes readily in acicuhir quadrangular prisms. These 

 are readily distinguishable from the nitrate of strychnine, which
