    SALTS OF STIlYCnNIA—ARRANGED ACCORDING TO THEIR DEGREES OF SOLUBILITY AND TOXIC POWER. Pliospho-vinato of Formiate Mallate ,, Fluosilicate ,, Acetate ,, Pyro -phospli ate ,, Meta-phosphate Ortho-phosphate ,, Acid sulphate ,, Hydrochlorate ,, Acid tartrate ,, Citrate ,, Arseniate ,, Arsenite ,, Gallate „ Nitrate ,, Nitrite ,, The above table is not by any means complete as regards all the salts of stryclmia, but contains only those which are more common, and to these I have confined my observations. I have also purposely avoided any attempt to classify the numerous double salts of this alkaloid, failing to perceive any useful end which could thereby be attained. These double salts have been carefully observed by various che- mists, and especially by Messrs Nicholson and Abel, to whose contributions on this subject I would refer those who may wish further information. Besides these, there is another series of chemical substances containing strychnia, and called substitution compounds, thus, there are methylstrychnia, ethylstryclmia, amylstrychnia, chlorostrychnia, and their various salts, but as these substances have already received considerable attention in their chemical relations from Messrs Stahlschmidt, How, Menetries, Schiitzenberger, Tilden, Hera- path, and Laurent, and in their physiological bearings from Messrs Crum Brown, and Eraser, I must refer the reader for information on this subiect to the Avritings of these observers. Pursuing further the properties of strychnia, w^e find that in the caustic alkalies, fixed and volatile, it is perfectly in- soluble. It is not, if pure coloured, on bemg treated with the strong mineral acids cold or boiling, but when, as is Strychnia. )) 1.J J JJUjJllUJsIJlll n IT viincnl nliif XXj jJUOUlUlllLC 11 Borate )) x^CLlllai tciL ITULe ») /wo 1 n rj» UAtlUlLC 1) bUiUXlUlC ) ) Chromate Bromide )) ]\Iellitate )> lodate 1) Iodide )) Sulphocyanate ji Carbazoate )) Taunate )i Metantiuioniate 1) Chloride )) )) )1 )) It ?) )) 5) 51 )) •) !) 1) )) 1) )) 1> M 51 51 5) 51 11 51
