Members Forum MOUNTAIN GORILLAS As conservationists working in the Parc National des Volcans of Rwanda, we are disturbed by Dian Fossey's inclusion of "tourist presence" among the factors she lists as contributing to the demise of the mountain gorilla. No other single factor has done so much, in so short a time, to im prove the chances of survival for the park-and hence gorillas-as the increase in park revenue, which is due solely to tourism. J. P. von der Becke M. Condiotti C. Aveling A. H. Harcourt R. J. Aveling Parc National des Volcans, Rwanda SOLAR SYSTEM The name of Earth's moon is Luna. Why has one of the most prominent celestial objects become unknown? Has Luna gone loonie? Pat Dimmick Cheshire, Connecticut Our moon is an orphan;no official name has been approved by the International Astronomical Union-neitherthe Latin namefor our satellite, Luna, nor the more common "moon," an ancient word related to month. METRIC SYSTEM The wonderful map "The Solar System" and ar ticle on Saturn were lost to me and, I'm sure, alot of other people. I could do no more than look at the pictures, feeling a sense of bewilderment be cause I cannot understand kilometers. Rev. George R. Ingham Oswego, New York This is the United States, and we are not giving it up for all the boneheads who believe they can push the metric system down our throats. Raymond K. LeClair, Sr. Old Tappan, New Jersey The voyage to Saturn was measured entirely in metric by the scientists involved; our account therefore was generally in metric, but contained equivalents in the English system we are used to. Eversince the U. S. government decided to move toward metric in 1975 andjoin most of the rest of the world in the way things are measured, pub lishers have found themselves betwixt and be tween. We use metric when it is advisable and appropriate, as in science articles, but include enough equivalents to enable easy translation. Presenting CLASSIC BLACK.
