O.R. Norton, Rock From Space, 2nd ed. 1998, p. 193:

CI carbonaceous chondrites => "... they contain the highest percentage
of water - 20 percent - of any carbonaecous meteorite. When heated in a
closed container, the water is easily driven off and condenses on the
side of the enclosing vessel."

CM carbonaceous chondrites => "... contain less water than the CI group,
only about 10 percent, ..."
