The distribution of diffuse [\N+] 205 $\mu$m emission perpendicular to the Galactic plane at $l = 7\fdg 28$ has been measured from the NASA Kuiper Airborne Observatory and is compared with the distribution of emission by other atomic and molecular species. The profile of [\N+] emission, characteristic of warm ionized gas, is modeled as a Gaussian of $12\farcm 9~^{+3\farcm 2}_{-2\farcm 5}$ HWHM. The distribution of [\C+] 158~$\mu$m emission, characteristic of predominantly neutral photodissociation regions, and first measured by Stacey et al. (1985) at the same longitude, has a Gaussian HWHM of $18\farcm 4~^{+1\farcm 9}_{-1\farcm 6}$. Line intensities are compared with those observed with the 7$\deg$ beam of the COBE FIRAS.
