Présentation de l'éditeur
This book of tables for every day use in the chemical laboratory is a revision and modification of my Tables for Chemical Calculations published about 16 years ago, and now out of print. The changes in our official atomic weights have made necessary a complete revision of most of the tables. A new table for facilitating the calculation of percentage compositions of organic compounds has been added, while, in order to make the book more compact and thus more convenient for its chief uses, several of the smaller, less important tables have been omitted, while the matter relating to the explanation of the tables and the illustration of their uses has been either left out or much changed and abbreviated. The table of logarithms of numbers has been provided with a double thumbindex which is believed to be a novel and useful device. With this improvement one can turn from any place in the table to any other reference, backward as well as forward, by practically a single motion, since all indices are visible from every part of the table. The greatest care has been used to secure accuracy in the data by the duplication, at least, of their derivation, with a complete verification after the plates were cast. There is no doubt that accurate calculation is exceedingly important in connection with quantitative analysis and other kinds of chemical work, and it is believed that these tables will be of assistance in avoiding errors of calculation, as well as in making the work more rapid and less laborious than is often the case.
