Document issued by the Office of the Attorney General of Texas in Austin, Texas, providing an interpretation of Texas law. It provides the opinion of the Texas Attorney General, Will Wilson, regarding a legal question submitted for clarification: Whether an appointment to an unclassified seasonal position disqualifies such appointee for later appointment to a classified position at a rate of pay not to exceed the mid-point, provided he has "markedly superior qualifications."

Technical progress is reported on research and development associated with the design of the Pathfinder atomic power plant. Preconstruction work is reported on fuel elements, reactor mechanical studies, and nuclear analysis. Other design work is reported on the oscillator control rod mechanism, a superheating calorimeter, and superheater thermocouple lead connectors. (J.R.D.)

The problem of crystal structure of the martensitic B1 phase of the eutectic alloy in the Cu-Al system still requires a more accurate clarification (Hun ger and Dienst 1960, Tarora 1949). Martensitic phases in general are formed through small thrust (shear) deformations of the original lattice. On this basis the results of Hunger and Dienst (1960) are doubtful, since the lattice constants found by them have required a considerable reclassification. From the known lattice constants of the B1 phase (Tarora, 1949) and the orientation relationships of the B1 phase (Wassermann, 1934) one has expected a hexagonal lattice for the martensitic phase with [formula].
