Following closely on Baron's article came an account of stylistic research carried out by the Polish scholar W. Lutoslawski in conjunction with his study of Plato's logic. Starting in 1891 he revealed from time to time details of his work, originally in Polish, but afterwards in periodicals of other countries. Later the fruits of his various labours were collected and published in one book. The greater part of it deals with the subject of the title; of concern here is only chapter 3 (pp. 64–193), entitled ‘The style of Plato’, which contains his investigation into the chronological order of the dialogues.

Lutoslawski's interest being primarily in Plato's logic and only incidentally in his style, he excluded from his inquiry not only suspected works, but also those ‘of no logical importance’. There remained twenty-two dialogues, the same as those accepted by Ritter as authentic together with the Parm., to be arranged in their order of composition. In contrast to earlier investigators he was acquainted with the achievements of all his predecessors, his own work being in fact a compendium of their inquiries. Knowing, therefore, that Campbell, Dittenberger, Schanz, Ritter and Arnim generally agreed on this, he regarded it as proven that Soph., Pol., Phil., Tim., Crit. and Laws constituted the last chronological group. His procedure was based on that of Ritter, the calculation of the number of ‘late’ linguistic characteristics in each dialogue, but whereas the latter used a mere 40 criteria, Lutoslawski aimed to amass 500.
