Mapping of the dark cloud L 134 N in (C-12)O and (C-13)O has shown that at least two subclouds are distinguishable spatially and in velocity. (C-12)O emission is distributed over an area of about 90 arcmin diameter with a maximum temperature of about 11 K; for (C-13)O these are about 50 arcmin and 4 K. Linewidths increase from the edge of the cloud inward to a peak of about 2.5 km/s at the position of the (C-13)O temperature maximum. Line velocities show much variation as a function of position, but the predominant emission component occurs at 2.5-3 km/s in the LSR frame. Comparisons are made with earlier observations of L 134 N and with recent observations of L 134.
