[364] As, for instance, strychnine racemate, a compound of racemic acid with the optically active strychnine. This would be resolved into strychnine d-tartrate and strychnine l-tartrate, which are not enantiomorphous forms.

[366] Solid models constructed of plaster of Paris can be obtained from Max Kaehler and Martini, Berlin.

[367] Instead of the present method of obtaining potassium chloride by decomposing carnallite with water, advantage might be taken of the fact that carnallite when heated to 168° undergoes decomposition with separation of three-fourths of the potassium chloride (van't Hoff, Acht Vorträge über physikalische Chemie, 1902, p. 32).

[369] These curves represent only portions of the isotherms, since the systems in which a ternary solution is in equilibrium with solid hydrogen chloride or a hydrate, have not been investigated.
