Description
Excerpt from Select Methods: In Chemical Analysis Chiefly Inorganic
A complete list Of separations has not been attempted. Where no process of separation or estimation is given, it may be inferred that the Author has had no experience in any but the well-known methods employed in most laboratories and to have introduced these ordinary processes into the work, simply for the sake of filling up gaps, would have largely increased its bulk without add ing materially to its value. To save space, the description of a process is frequently discontinued at the point where the sub stances under separation are brought to such a state that the concluding steps are obvious.
NO special system of weights and measures has been employed many of the descriptions having been condensed from the original memoirs, it was thought better to retain the system therein adopted, so as to have simple numbers to deal with, instead of having to convert them to one common scale and to introduce decimals. Thus, when an author says, take 8 grains of a sub stance, O°51816 gramme has not been substituted; and where 10 grammes are mentioned, he has not put i54°ss4o grains. When not otherwise expressed, all degrees are according to the Centigrade scale. Formulae have been avoided as far as practicable.
