The purpose in A Handbook of Chemical Analysis is to meet the needs of teachers who present this subject to student who do not have the time or perhaps the inclination to pursue it in depth, but who may also require explicit coverage of basic topics. This book, therefore, introduces material in an elementary fashion, and presents only the main facts.
The point, however, is that this book does present the facts in a systematic way. One can appreciate the sound of music without knowing anything of musical theory although of course one's appreciation is enhanced by knowing some theory. However, a book of musical theory, even if it is illustrated by audible snatches of themes and a few chord progressions, is quite unlike the hearing of a real composition in its entirety.
