Features of the enema nozzle and bag

For niruha and anuvasana enemas an apparatus is made with a leak-proof bag of strong, soft leather holding eight kudava of fluid (the commentary adds 128 tola, with a query) and a nozzle 6, 8 and 10 angula long for children, youths and young adults. Near its tip is a round collar (karnika) measured at one, two or three angula; its thickness equals the little finger at the tip, the ring finger in the middle and the middle finger at the base, and it is shaped like a cow's tail with a rounded tip. The verse gives some numbers in Jain technical words, which footnotes explain.
