IN the preparation of this revised and extended edition, we have
had in mind two major factors.
First, considerably greater emphasis has been placed on semimicro techniques and their application to preparations, separations, analysis and physical determinations such as those of
molecular weight. We have therefore greatly expanded the
section on Manipulation on a semi-micro scale which was in the
Third Edition, and we have described many more preparations
on this scale, some independent and others as alternatives to
the larger-scale preparations which immediately precede them.
Some 40 separate preparations on the semi-micro scale are
described in detail, in addition to specific directions for the
preparation of many classes of crystalline derivatives required
for identification purposes. The equipment required for these
small-scale reactions has been selected on a realistic basis, and
care has been taken not to include the very curious pieces of
apparatus sometimes suggested as necessary for working on the
