Excerpt from Simple Methods for Detecting Food Adulteration We hope that this little book will be useful in more ways than one. It contains a series of samples for experiment, and another for observation, each of which by itself should be of educational value. The experiments are simple, consisting for the most part of the application of chemical tests, the results of which must be carefully noted, and the comparing of weights of certain substances, generally called "taking their specific gravity." The observations bring in the use of the microscope; these will be better performed by a more elaborate than by a cheaper microscope. It is not, however, the privilege of everybody to have the use of an instrument of very high power. Each must, therefore, do his best with the instrument at his command.
