Spectra obtained with the 6-m telescope of the Special Astrophysical Observatory have been used to make a detailed spectrophotometric investigation of the spiral galaxy Mark. 307. For the nuclear region and five condensations in the spiral arms, the relative intensities of the emission lines have been used to estimate the values of T/sub e/ and n/sub e/, the abundances of the elements O, N, and S, the masses and volumes of ionized gas, and the number of 09 stars. On the basis of its parameters, the nuclear region of the galaxy is identical to the nuclei of spiral galaxies. One giant H II region is distinguished among the condensations by all its physical parameters; the scale of star formation in it probably exceeds that of the nuclear region of the galaxy.
