"Ya. A. R ospina" (garbled name, unverified)

The third editor credited in the closing attribution of this volume's editorial back matter, responsible for the texts and notes to the September-December 1887 letters; the name is corrupted in the source (an internal space splits what should likely be a single surname, and the initials do not obviously match any editor otherwise associated with this edition), possibly a scanning/OCR artifact of "N. A. Roskina," but preserved literally per the translator's note rather than silently corrected. Treat this credit as unverified pending the printed original.
