PREFACE TO THIRD EDITION.
The call for a Third edition of this little book, after two editions of two
thousand copies of each have been exhausted within three years, is certainly
gratifying to the author, and assures him that his aim to present it as an aid
to the medical student in his pursuit of chemistry has been realized. He thinks
that this compend has not interfered with more thorough reading from text-books,
but has helped to make these better understood, and has thus rendered the path
of the medical student in this direction less difficult.
It was not found necessary materially to enlarge the subject of this edition.
But the text has been carefully gone over. A few errors were corrected, and
several tables, of the elements, weights and measures with rules for converting
them, thermometric scales, etc., were appended.
Trusting that this issue will have the same generous reception from all parts of
the country which has been accorded to the former editions, the author hopes
that it will be a welcome friend to the student, which will help him better to
appreciate the subject under consideration, and in doing so extend his
usefulness as a medical practitioner.
L.W.: August, 1891.
PREFACE TO FIRST EDITION.
An Extensive experience in preparing medical students for examination in
chemistry has satisfied the write that the incomplete knowledge of this
department of medical science, so often exhibited by students and physicians, is
generally due to their inability to study the subject thoroughly without
encroaching in too great a degree on the time required for the more practical
branches of their profession.
Most students appear to be justified in claiming that they have derived much
profit from the systematic course of "quizzing" which is in vogue at the medical
schools. This benefit is attributable, no doubt, to the fact that by this mode
of instruction essential points are brought out in the form of questions which
exact attentive consideration before adequate answers to them can be given.
In the volume here presented the author has the same object in view, while he
trusts that it will not be the means of dispensing with the deeper study of the
subject, he feels assured that unless the frame-work of knowledge be first well
constructed, substantial progress will be quite impossible.
If this little work shall tend to give students a better understanding of
chemistry, and with it a greater love, or perhaps less of a distaste, for the
pursuit in connection with their medical studies, the writer considers that he
will have achieved much of what he attempted.
As an introductory course to chemistry in most, if not in all, medical colleges
includes the principles of physics, some essential questions on this subject
precede the chemical part of the work. Theoretical chemistry, though treated in
a separate chapter, is also frequently referred to throughout the text. The
classification of the elements is somewhat at variance with the most modern
ideas of pure chemistry, but it has been given with the view of presenting the
matter in logical sequence to the medical mind. Toxicology has received ample
consideration under the head of each element or compound which possesses
markedly poisonous properties. Analytical processes have been brought out as far
as compatible with the condensation of so large a subject within so limited a
space. No separate chapter or part is devoted to the "urine and its analysis,"
its components being considered in the order of their precedence in the adopted
arrangement.
The questions and answers of this manual have been so arranged as to conform to
the principle text-books on the subject. For this purpose the authoritative
works of Fownes, Attfield, Richter, Charles, Barker, and Witthaus, as well as
Holland on the urine, and Draper and Ganot on physics, have been freely used in
its preparation
