Data from essentially all heliographic latitudes (50 ¿S to 60 ¿N) are used to demonstrate directly the anticorrelation between the solar wind speed and the coronal density to which it maps. The data, coronameter observations of density and interplanetary scintillation measurements of wind speed, are well suited for comparison, since they have similar selection effects, both responding most accurately to large-scale structures. Their relationship is demonstrated on time scales from 2 days to 1 year for the years 1972--1975, during which the structure were corotating or slowling evolving. This study makes a quantatitive point-by-point comparison of coronal density and solar wind velocity, in contrast to earlier comparisons where holes were parameterized by their area and streams by their maximum speed.
