Numerical solutions have been obtained for steady viscous flow past a circular c..-l;nder a t Reynolds numbers up to 300. A new technique is proposed for the boundwy condition a t large distances and an iteration scheme has been developed, based on Newton's method, which circumvents the numerical difficulties previously encountered around and beyond a Reynolds number of 100. Some new trends are observed in the solution shortly before a Reynolds number of 300. As vorticity starts t o recirculate
