The Society's Rules appear to have been settled in 1797, printed in 1798, and revised in 1810 and 1827. Meetings were held regularly on Thursday evenings, and mainly consisted of debates: in the early days, this seems to have been what distinguished the Cymreigyddion from the Gwyneddigion, among whom debating had fallen into abeyance. Other activities included a strong social element and the dispensing of charity. Proceedings were held in both
Welsh and English, and one of the Society's objects was the teaching of English to Welsh newcomers to London. In its later years it held lectures and organised
eisteddfodau, and seems to have acquired a
radical political character. The Society was (like the Gwyneddigion) anti-
Methodist, and revelled in the disgrace of the preacher
Edward "Ginshop" Jones, sued in a
breach of promise case in 1801: it published a 24-page booklet containing the texts of Jones's love-letters, which had been read out in court, and a ribald ballad about the affair by Glan-y-gors. The Cymreigyddion always seems to have been a more "democratic" body than the Gwyneddigion, and in the early 19th century, as the Gwyneddigion fell into decline, the Cymreigyddion to some extent took over the membership of the older society. ==Legacy==
