A fourth interpretation of the observed variations in abundances could invoke relatively small differences in the solubility of volatiles in metallic H. Approximately 85% of Jupiter's H is in the metallic phase. For instance, the mixing ratio of a minor constituent in the molecular part of the planet is much larger than the solar value, because this mixing ratio in the metallic interior is somewhat smaller than the solar value or vice versa.

We thank J. Cooley for his efforts as instrument manager; R. Lott and T. Tyler for the mechanical design contributions; A. Doan for his help in the enrichment cell design; R. Abell, H. Powers, and H. Mende for the precision assembly welding and machining; and R. Arvey and H. Benton for the electronics assembly and testing at Goddard Space Right Center. The contributions to the electronics system design of B. Block, J. Caldwell, J. Eder, J. Maurer, and W. Pinkus at the University of Michigan are gratefully acknowledged. The hybrid electronic circuits were fabricated at the General Electric Astro Space Division at Valley Forge, PA, and the microvalves for the gas sampling System were designed and fabricated by Aker Industries in Oakland, CA. The capillary leak arrays and secondary electron multiplier detector were manufactured by Galileo Electro Optics in Sturbridge, MA. The chemical getter material was provided by the SAES Getter of Milan, Italy. M. Wong of the University of Michigan participated in the data analysis. We also thank the Galileo Probe Project personnel at NASA Ames Research Center, and we particularly acknowledge the contributions of A. Wilhelmi, C. Sobeck, and P. Melia for their efforts during the development, spacecraft integration, and testing phases.
