We have constructed a volume-limited catalog of normal spiral galaxies within the redshift interval 0-4000 km s-1 and brighter than 1.9 Jy at 60 μm to study relationships between fundamental galaxy properties and to map to the peculiar velocity field. Herein we report observations of 57 galaxies from this sample at Jodrell Bank, 42 of which resulted in detections, and study relationships between far-infrared and neutral hydrogen properties. Gas and dynamical or halo mass are well correlated with each other and moderately so with far-infrared luminosity. A decrease in dynamical mass with increasing farinfrared color temperature suggests that less massive, later-type systems enjoy higher speci..
