For the past fifteen years rather extensive investigations have been carried on in this laboratory concerning the thermal dissociation of the hydrides of the alkaline earth metals. During this oeruid considerable time has been spent in devising suitable apparatus for the work and improved methods of procedure. Each successive worker on the problem in this laboratory has contributed materially to some phase of the investigations, or at least suggested from his experience improvements to be made in existing methods.It is however, unfortuneate that, because of the nature of the course in which these investigations have been undertaken, time for research has in each case been limited to one academic year. As a period of apprenticeship in working with a vacuum system is adviseable is not necessary, and unforseen difficulties have arisen in the past even after the system had been placed in good working order, this time limit has in several instances curtailed work which at the time gave promise of success.
