viii OPTICAL PROJECTION It is under these sad circumstances that I have taken up the pen in order that, as nearly as possible, the fourth edition should be presented to the public as it would have been had the Author been spared to revise it. So far as possible I have preferred to leave my father's original work untouched, a few paragraphs slightly altered and a footnote here and there comprise all the alterations that have been made, and the bulk of the work has consisted in writing a new and fairly voluminous Appendix describing many of the more modern optical instruments. In doing so I have followed, so far as possible, my father's plan of including no instruments or experiments that I cannot speak of from practical experience. With hardly an exception every paragraph in the new Appendix has been written from my own personal knowledge. In a work of this class, dealing as it does with the easiest and most convenient way of handling apparatus, to do otherwise would be dangerous and unwise, and this must be my apology if omission has been made of any new appliances which should have been included. KUSSELL S. WEIGHT. June 1906.
