Excerpt from Laboratory Notes in Household Chemistry for the Use of Students in Domestic Science
The following pages are written as a guide and introduction to the study of household science. It is not the object of the authors to put forth a work on the analysis of food and other kindred subjects met with in the practice of domestic science; their sole aim is to throw some light upon the composition of food and other materials to the end that those practicing this most useful of arts may achieve better results by understanding the more important properties of materials with which they deal.
Some knowledge of chemistry, both general and organic, is necessary and a clear idea of the essentials of physics is indispensable.
It is hoped that teachers using the manual will communicate with the authors in regard to any suggestions or improvements.
The book is a pioneer in the subject and may be criticized on account of the selection of subjects; they are, however, those which have in the course of three years proved most useful to the authors' classes.
The common and metric systems of weights and measures are used in the manual; in all exact experiments the metric system has been given the preference, but in cases where the experiment has a direct bearing on domestic science the common household units have been brought into play.
