[1631] Scammony was quoted in a London price current, April 1874, at 8s. to 36s. per lb., Resin of Scammony at 14s. per lb.
[1632] Thus 100 bales were offered in a drug sale, 3 July 1873.
[1633] Such was the case at Aleppo, as we know by a private letter from Mr. Consul Skene.—D. H.
[1634] Thus at Ootacamund, Mr. Broughton, in a letter to one of us (15 January 1870), speaks of receiving “a cluster of tubers” weighing over 9 lb., and remarks that the plant grows as easily as yam.

[1638] It is plain that such a proceeding is irrational. The roots should be dug up when the aerial stems have died down.
[1639] Linnæa, iii. (1830) 473; Pharm. Journ. viii. (1867) 652.—We are not aware of any more recent account.
[1640] Guibourt obtained of it 17 per cent., Umney 21·5, Squibb 11 to 16, T. and H. Smith “not more than 15,” D. Hanbury 11 to 15·8. Jalap grown in Bonn afforded to Marquart 12 per cent.; a root cultivated at Münich gave Widnmann 22 per cent.; from plants produced in Dublin W. G. Smith got 9 to 12 per cent.; and fine tubers from Ootacamund in India yielded to one of us 18 per cent. of resin. Broughton is of opinion that exposure of the sliced tuber to the air in the process of drying, favours the formation of resin, by the oxidation of a hydrocarbon.
