Abstract
The relation between mass loss rate and pulsation period in carbon Mir as is discussed. The dust mass loss rate is very low (about 2 x 10(-10 ) M./yr) up to about P = 380 days, where there is a sudden increase. F or P > 400 days there is a linear relation between log M and P. The ch ange in the mass loss rate near 380 days may be related to radiation p ressure on dust becoming effective in driving the outflow.
