Vapor densities and/or dissociation pressures of UO/sub 2/, ThO/sub 2/, ZrO/sub 2/, ThO/sub 2/-8 and -20 wt % UO/sub 2/, and ZrO/sub 2/-20 and -50 wt % UO/sub 2/ were obtained in the range from 2000 to 3000/sup 0/K by the transpiration technique. The UO/sub 2/-ZrO/sub 2/ system exhibited marked positive deviation from ideality, indicative of a strong tendency toward immiscibility. The UO/sub 2/-ThO/sub 2/ system was found to behave almost ideally. On the basis of the vapor pressures of UO/sub 2/ and of ThO/sub 2/ and the activity values it would be expected that compositions containing 1 mole % or more of UO/sub 2/ would volatilize by preferentially losing UO/sub 2/. A composition containing slightly less than 1 mole % UO/sub 2/ should prove to be the congruently subliming composition. O/sub 2/-dissociation pressures were determined for stoichiometric UO/sub 2/ and for a composition on either side of the stoichiometric one. At 2360/sup 0/K, UO/sub 2.03 +- 0.01/, UO/sub 2.00 +- 0.01/, and UO/sub 1.97 +- 0.01/ exhibited O/sub 2/-dissociation pressures of 1 x 10/sup -7/, 4.3 x 10/sup -10/, and 3 x 10/sup -12/ atm, respectively. From determinations of vapor density and measurements of O/sub 2/ pressure, pressure-temperature-composition relations …

The following report summarizes the geological and geophysical studies made on the rocks of the Midi Mist site in the Area-12 tunnel complex of the Nevada Test Site. The data was needed to determine whether the rock met the technical criteria of the nuclear experiment.

Office memorandum addressed to J. M. Souter. The memo, which was written by P. G. McCaghren, states that Mr. Emery Richard Whetstone called the Police Department at 1:20 AM. Whetstone, who spoke as if he were intoxicated, said that Franklin Folley (the drummer in Frank Sanatra's band) shot President Kennedy.

Abstract: "Fifteen in situ interval densities were calculated from the borehole gravity meter observations made in Test Well-B. The weighted average density for all the rocks sampled by the gravity meter is 1.83 gm/cc. The alluvium density ranges from 1.71 to 1.82 gm/cc and averages 1.76 gm/cc. The lake beds range from 1.91 to 1.93 gm/cc and average 1.92 gm/cc. The Rainier Mesa Member averages 1.83 gm/cc. The Tiva Canyon Member averages 1.74 gm/cc and the upper 110 feet of Topopah Spring Member has a density of 2.30 gm/cc."
