It is unnecessary to plot these data, for with the exceptions 

 of urethane in water and chloral hydrate in chloroform, the 

 curyes are quite regular. In the cases of urethane and chloral 

 hydrate, the curyes change direction very suddenly at about 

 12°, showing a very sudden decrease in solubility as the tem- 

 perature decreases from this point.
