The first study of any portion of mathematics should not be done from a synopsis of compact results, such as this collection.
The references, although they are far from complete, will be
helpful, it is hoped, in showing where the derivation of the results
is given or where further similar results may be found. A list
of numbered references is given at the end of the book. These
are referred to in the text as "Ref. 7, p. 32," etc., the page num-
number being that of the publication to which reference is made.
