Sinopsis

Excerpt from Chemical Arithmetic, Vol. 1: A Collection of Tables, Mathematical, Chemical, and Physical, for the Use of Chemists and Others

The Reciprocal Table is simply a reprint of the one which formed part of the old'edition but, in correcting the proofs, instead of merely following that edition, I re - read all the reciprocals with Barlow's table, and, I am glad to say, found no error. A four-place table of reciprocals is a little ahead of a four - place table of logarithms in point of precision, and it is obviously the more convenient table of the two whenever the reciprocal is wanted for its own sake. Now, such cases occur nowhere more frequently than in practical chemistry. To give only one example, and there are plenty of analogous cases. Supposing we have found that 1 CC of standard solution A neutralises x CC of solution B, and we want to know the number of CC of A which corresponds to 1 CC of B. The reciprocal table gives the answer quite directly, and on this account more exactly than the logarithm table does.
