It is argued that infrared data (3-micron and 3.4-micron features corresponding respectively to OH and CH stretching frequencies) clearly bear out the predictions of models in which a cellulose-like molecule makes up a large fraction of all the dust. A predominantly inorganic water-ice composition of the grains would appear to be ruled out by this data because of the excessive mass absorption coefficient of ice at 3.05 microns. It is concluded that these indications, combined with the further indication that C, N, and O must provide the main mass contribution of grains, make the argument for an organic composition of interstellar grains quite overwhelming.
