PREFACE.
To embody in a condensed form somesalient features of the present status of Food Adulteration in theUnited States is the object of this volume. The importance of thesubject, and the apparent need of a book of moderate dimensionsrelating thereto, must suffice as its raison d’être.The standard works have been freely consulted, and valuable data havebeen obtained from the recent reports of our State and Civic Boards ofHealth. The system of nomenclature accepted by the American ChemicalSociety has been generally adopted. It was, however, deemed advisableto retain such names as glycerine, sodium bicarbonate, etc., in placeof the more modern but less well-known terms, glycerol and sodiumhydrogen carbonate, even at a slight sacrifice of uniformity.
The photogravure plates, most of which represent the results ofrecent microscopical investigation, are considered an important featureof the book. And it is believed that the bibliographical appendix, andthe collation of American Legislation on Adulteration, will supply awant for ready reference often experienced.
