CV BURR PRINTING HOUSE, FRANKFORT AND JACOB STREETS, NEW YORK. A KEY TO ALL THE QUESTIONS AND EXAMPLES CONTAINED IN THE EXAMINATION QUESTIONS INCLUDED IN THE PRECEDING VOLUmes. The Keys that follow have been divided into sections corresponding to the Examination Questions to which they refer. The answers and solutions have been numbered to correspond with the questions. When the answer to a question involves a repetition of statements given in the Instruction Paper, the reader has been referred to a numbered article, the reading of which will enable him to answer the question himself. To be of the greatest benefit, the Keys should be used sparingly. They should be used much in the same manner as a pupil would go to a teacher for instruction with regard to answering some exatnple he was unable to solve. If used in this manner the Keys will be of great help and assistance to the student, and will be a source of encouragement to him in studying the various papers composing the Course. |
