PREFACE.
The importance of exact chemical analysis in a great variety of cases which
come before the courts is now fully recognized, and the translation of this
excellent little book on Legal Chemistry, by one of the most distinguished
French Chemists, will be appreciated by a large class of American readers who
are not able to consult the original. While it is to be regretted that the author
has not presented a much more complete work, there is an advantage in the
compact form of this treatise which compensates, in some degree, for its
brevity.
The translator has greatly increased the value of the book by a few additions
and his copious index, and especially by the lists of works and memoirs which
he has appended; and while he could have further increased its value by
additions from other authors, we recognize the weight of the considerations
which induced him to present it in the form given to it by the author. Some
chapters will have very little value in this country at this day, but the translator
could not, with propriety, omit anything contained in the original.
C. F. Chandler.
PREFACE TO THE SECOND EDITION.
The principal change to note in this edition of the LEGAL CHEMISTRY is the
addition of a chapter on Tea and its Adulteration. The general interest at
present evinced concerning this species of sophistication appeared to call for a
simple and concise method of examination which would include the requisite
tests without entering upon an exhaustive treatment of the subject. The
translator's practical experience in the testing of tea at the United States
Laboratory of this city has enabled him to make a few suggestions in this
regard which, he trusts, may be of use to those interested in food- analysis.
Numerous additions have also been made to the bibliographical appendix.
J. P. B.
