Publisher's Synopsis
THERE is no department of inquiry in which it is not full as easy to miss truth as to find it, even when the materials from which truth is to be drawn are actually present to our senses. A child does not catch a gold fish in water at the first trial, however good his eyes may be, and however clear the water; knowledge and method are necessary to enable him to take what is actually before his eyes and under his hand. So it is with all who fish in a strange element for the truth which is living and moving there: the powers of observation must be trained, and habits of method in arranging the materials presented to the eye must be acquired before the student possesses the requisites for understanding what he contemplates.
