We present the results of an investigation
of the large-scale structure of the diffuse interstellar medium
in the 2
Galactic Quadrant (
).
145 loops were identified on IRAS-based far-infrared maps.
Our catalogue lists their basic physical properties.
The distribution clearly suggests that there is an efficient
process that can generate loop-like features at high Galactic latitudes.
Distances are provided for 30 loops.
We also give an observational estimate of the volume filling factor
of the hot gas in the Local Arm,
.
