We have re-analysed all available high-resolution
ultraviolet IUE spectra of the high-mass X-ray binary
HD 153919/4U 1700-37. The radial velocity semi-amplitude of 
km s-1 and orbital eccentricity of 
agree very well
with the values obtained earlier from optical spectra. They disagree
with earlier conclusions for the same data reduced by Heap & Corcoran
([CITE]) and by
Stickland & Lloyd ([CITE]).
