Errata for Blyth & Pozrikidis (2004) "Evolution equations for the surface concentration of an insoluble surfactant; stability of an elongating thread and a stretched interface" Theor. Comp. Fluid Dynamics, 17(3), 147 - 164.

In equation (5.10), the factor of 1/2 in the first term on the right hand side should be inside the bracket multiplying only the G(t) term.

In equation (3.5), the term $v_x$ should be premultiplied by a scale factor to reflect the change of the derivative from d/dx to d/dl (partial d's). The same comment applies in the appropriate places throughout the paper. For example, for a two-dimensional interface in section 4, in equations (4.2) and (4.3) $v_x$ should be replaced with $\sqrt{1+f_x^2}v_x$. On making this change, it is informative to note that (4.3) reduces to equation (2.4) of Halpern & Frenkel (Journal of Fluid Mechanics, V. 485, 2003).
