The scientific terms for these operations are taṭliyah and tajrí', though we might expect taṭliyah and tánshíq, because tanshíq means injecting into the nose.

For each Bughdí and Jammázah 3¾ sers of sesame oil are annually allowed, viz., three sers for anointing, and ¾ ser for injection into the nose. So also ¾ s. of brimstone, and 6½ s. of butter-milk. For other kinds of camels the allowance is 5/8 s. of brimstone, 6½ s. of butter-milk, and ¾ s. of grease for injecting into the nose-holes.

Formerly these operations were repeated three times, but now only once a year.
