The amount of suspended carbon present in a culture of Tetrahymena can be measured, with the aid of a colorimeter, before and after the ciliates have fed, and this difference can be regarded as an index of ciliary activity. This can be varied by changing the culture conditions. When transferred from a proteose-peptone medium to distilled water containing carbon 106, T. pyriformis can remove the carbon from 6-10 ml medium per hour.
