Cryoscopy is, in brief, the determination of the freezing point of fluids containing substances in solution. The following are the principal laws deduced by Raoult and others from the study of the freezing point of solutions: 1. All substances, solid, liquid and gaseous, when dissolved in a definite liquid capable of solidification, lower the point of solidification, and this the more the greater the concentration of the solution. 2. If the body dissolved is not combined with or altered by the water of the solution, the lowering of the freezing point is proportional to the molecular weight of the substance dissolved. 3. The solution of an equal number of molecules in a constant quantity of water lowers the freezing point to the same extent no matter what the nature of the substance dissolved may be. 4. When various substances are dissolved in the same solution, the lowering of the freezing
