Indologists have at this time of day come to know how prominent is the part played by numbered categories in the Pali Canon. The whole of the Fourth Nikāya, the Anguttara, is composed of such. The two last Suttantas of the First Nikāya: the “Sangīti” and the “Das-uttara”, are composed of such. Five Suttas of the Second Collection: “Bahuvedaniya, Chabbisodhana, Bahudhātuka, Mahācattarīsaka, Pañcattaya,” have numerical title and treatment. The Third Nikāya alone, the Saṃyutta, has not conformed to this method. In the case of the Anguttara- and Dĩgha-Nikayas the subjects are not only grouped under numbers, they are taken in arithmetical progression: the Ones, Twos, Threes, etc. (That the Anguttara progression should cease at the Elevens, as though it were a cricketing chronicle, has not yet been inquired into, if I may except myself (in my re-written Home University Library Buddhism, 1934).) The lists are apparently out to exclude nothing which will have been of doctrinal importance to the compilers, whenever and wherever that compilation took place.
