Reading edition
In the mountains near Derabad, in Affghanistân, a kind of naphtha is obtained by placing flocks of wool on the places where it oozes from the earth. It contains a mixture of bitumen, supposed to be mumia, and is less pure than the Persian. Vigne, Affghanistân, p. 61, seq. Masson, Balochistân, &c. i. 115.
