SPECTROSCOPY

As full details as possible have been given of the methods of working with the various types of instruments. In the many branches of Applied Spectroscopy as distinct from the statistical work it has been quite impossible to deal with the great number of researches of the present time. Typical investigations have therefore been selected both with the view of indicating the lines upon which present work is being carried on and further in the hope which I trust is not a vain one that more workers may be encouraged to enter this fascinating and prolific field of research.
