(I*) Ackmwkdgement-I am sincerely grateful to the referee of this paper for his invaluable comments which led to the improvement of the paper. I am also grateful to Prof. P. H. We observe here from (12) that the velocity still increases Calderbank, Department of Chemical Engineering, Uniwith time at a given point.

Thus for small v/dR*, the flow of elastico-viscous fluids exhibits boundary layer characteristics. Conversely, when v/agR4 is large, the velocity is strongly dependent on position and there is no boundary layer. For K = 0, this problem reduces to that considered v,. by Sanyal(3) Proceeding as in Ref.
