[Footnote 157: Opium, called here Teryak, is prepared in the south-eastern part of Persia as follows:--The head of the poppy has incisions made in it lengthways on three of its sides at a fixed time in the evening, and when only half ripe. The next morning after it has been so cut a dew-like substance shows itself at the place; this must be removed before sunrise, and, after having been boiled, the resulting product is the Teryak. It is singular that from the three places where the poppy has been cut issue substances of different quality, and of these that in the middle is most esteemed.]
