Section VI. — General Description of Tables. 



§ 33. In the tables giving the results of the experiments made with solutions of a 

 particular salt, the weights given are those which would have been used if the 

 weighings had actually been made in a vacuum ; and the standard temperature, T, 

 at which all the operations have been made, is given at the top with the name of the 

 salt, both being constants. 



Of the variables, we have under m the quantity of the salt, expressed as the number, 

 whole or fractional, of gram-molecules, which is dissolved in 1000 grams of water, under 

 W the weight in grams of the solution so produced, and under S the specific gravity 

 of the solution referred to that of distilled water as unity, both having the standard 

 temperature T. 



With the exception of the determination of the temperature, the result of every 

 series of operations depends only on determinations of weight, and they are independent 

 of the work of others. Even the tyro has no difficulty in being assured of the true 

 weight of the hydrometer when floating up to the same mark in the solution and in 

 distilled water respectively. The difficulty which requires manipulative skill, laboratory 

 experience, and perseverance to overcome, is to satisfy the condition that the 

 temperatures of the solution and of the distilled water respectively, and that of the
