The Pre-Śiromaṇī age, 2.Raghunātha Śiromaṇī, 3. Bengali Commentators on Śiromaṇī, 4. The Post-Gadādhara Era, 5. Bengali Naiyāyikas in Kāśidhāma, 6. Nyaya Schools of Bengal. The author, with sufficient historical evidence, determines the time of many of the Navya-Nyāya scholars and he also proposes his views on the authorship of many of the Navya-Nyāya commentaries.
