A print of Minkowski's photograph of the planetary nebula NGC 7293 was used to obtain equidensities for two sections of the inner boundary of the ring of this object. The morphology of the radial filaments and the small condensations observed in NGC 7293 was investigated. It was found that in the typical case the filaments consist of several condensations enveloped in a faint irregular shell. The filaments do not protrude into the bright ring of the nebula and are not connected with the structure of its outer edge. Within the ring, there are numerous small condensations that are the remnants of filaments. The filaments and condensations in NGC 7293 may be relics that have survived from the epoch of ionization in the nebula. They are uncovered by the outflow of gas from the inner surface of the nebula and then rapidly disperse. The characteristic sizes of the filaments and condensations together with their relative density and lifetime are estimated.
