THIS little work is designed to aid teachers who are using the Fourteen Weeks Course. The problems contained in all the books are fully, and, it is thought, accurately solved. Great pains have been taken to revise and compare them carefully. The practical questions are answered, often not in full, yet enough so to give the key to the more perfect reply. The use of the text-books is presupposed, and the statements merely supplement, or apply the fuller theories therein contained and explained. On many points there may be a difference of opinion. The author often finds in his own classes a wide diversity. On mooted questions he has merely advanced one view, leaving the subject open for the discussion of other theories. Minute directions are given, pages 71-82 inclusive, for performing a course of experiments in Chemistry. It is hoped that these may be of service to teachers who, with incomplete appadatus, are trying to illustrate to their pupils some of the principles of that science. In all cases of doubt or misunderstanding with regard to the answers or solutions, the author will be pleased to correspond with any teacher using the Series ELMIRA, Mdrch 19, 1870
