Subject index mercuration

Venus is completely covered with dense clouds. The composition of the clouds has been the subject of much speculation for many years. It includes ice, carbon suboxide, sulfuric acid, hydrocarbons, mercuric chloride, ammonium chloride, and hydrated ferrous chloride. Recently, Young (1066a) has proposed, based on refractive index measurement, that the clouds are composed most probably of droplets of 75% H2S04.
