PREFACE
A brief statement of the general policy adopted in the construction
of this book perhaps will reveal most easily the points of departure
from the manuals already available for use in laboratory courses of
anic chemistry. It has e the practice in this
country to provide the beginning student with carefully standardized
and detailed directions, in order that a good technique may be acquired
with the greatest possible economy of time and materials, and to this
policy I subscribe wholeheartedly. There is no novelty in the prefer-
ence for preparations rather than experiments involving only test
reactions, or in the opinion that the most stimulating and useful
preparations are those which proceed smoothly and in good yield.
It is hardly necessary in these days to state that every effort has been
made to keep the cost of chemicals at a minimum, and a few prepara-
tions which have e old favorites have been abandoned regret-
fully for this reason. Careful attention has been given to the matter
of utilizing the products accumulating from one experiment as starting
materials for other preparations, for this plan is both economical and
instructive.
Less orthodox is the view that some of the reactions of aliphatic
chemistry can be illustrated perfectly well, and to considerable
advantage, with the use of pounds. Some of the trans-
formations characteristic of the aldehydes, acids, halides, and esters
proceed particularly well when simple aromatic substances are em-
ployed as the starting materials, and the use of s
