Medullic and margaric acids, which were formerly included in this
series, have now been shown to consist of mixtures of stearic and
palmitic, and stearic palmitic and oleic acids respectively.

The acids of this group are saturated compounds, and will not combine
directly with iodine or bromine. The two first are liquid at ordinary
temperatures, distil without decomposition, and are miscible with water
in all proportions; the next four are more or less soluble in water and
distil unchanged in the presence of water, as does also lauric acid,
which is almost insol
