The chemical composition of the photosphere and the corona
Collected photospheric and coronal abundances are presented in tables as summarized from a variety of references. A fairly complete picture of the composition of the solar photosphere for the first 92 elements is developed. Photospheric and coronal abundances are equal to within a factor of 2 (0.3 dex).

The chemical composition and energy content of the energetic cosmic radiation
A brief survey is made of our present knowledge of the composition and energy spectra of the primary cosmic radiation. The total energy carried by all forms of cosmic radiation that have appreciable penetrability into matter has been evaluated.

Chemical composition of lunar anorthosites and their parent liquids.
Data obtained in a trace element analysis of some anorthosite and anorthositic fragments are presented. The low Mg concentrations of the Apollo 15 anorthosite and the KREEP anorthosite reflect the mineralogical purity of these samples. They are so pure that their composition can be taken as that of liquidus plagioclases. Some of the characteristics of the parent liquids of these plagioclases can be calculated from the liquid-plagioclase distribution coefficients.

The chemical composition of soil from the Apollo 16 and Luna 20 sites.
The concentrations of the rare earth elements K, Rb, Sr, Ba, U, Zr, and Cr for the Luna 20 soil and four different Apollo 16 soils are reported. These trace element abundances imply: (1) that the lunar highlands consist of a mixture of rocks rich in large ion lithophile (LIL) elements and LIL-element improverished anorthosites; or (2) that the bulk of the aluminum-rich crust did not originate by upward segregation of plagioclase in a primitive liquid shell. The Luna 20 soil is distinguished from the Apollo 16 soil by lower aluminum and LIL element abundances.

Chemical composition of Luna 20 rocks and soil and Apollo 16 soils.
Review of the abundances of 24 major, minor, and trace elements measured by instrumental neutron activation analysis in Luna 20 metaigneous rocks, breccia, and soil, and in Apollo 16 soils. The similarities and differences observed are discussed. The bulk compositions of Luna 20 and Apollo 16 rocks and soils show close similarity between the two highland sites. Interelement correlations observed previously for maria are also found in highland samples. Luna 20 and Apollo 16 soils are low in alkalis. Both soils show an apparent Cd-Zn rich component similar to that observed at the mare sites and high Tl abundances relative to mare sites.

The chemical composition of population I stars.
A comparison of observed and theoretical mass-luminosity relations for unevolved stars in high-mass eclipsing binary systems and in low-mass visual binary systems is used to find the hydrogen and metals abundances of Population I stars: X = 0.69 plus or minus 0.12 and Z = 0.036 plus or minus 0.039. Alternatively, by adopting Z = 0.03 plus or minus 0.01, one finds X = 0.71 plus or minus 0.03. Limitations of the method are discussed briefly.
