Clusii Atrebatis Exoticorum lib. sept._, p. 157, 1605, fol.), and stated to have been derived by the Arabs from the Greek name, the term less commonly used by them being _Conder_: cf. Sanskrit _Kunda_. According to Colebrooke (in _Asiatick Res._ ix. p. 379, 1807), the Hindu writers on Materia Medica use for the resin of _Boswellia thurifera_ the designation _Cunduru_. [5] A term applied also to the resinous exudation of _Pinus longifolia_ (see Dr E. J. Waring, _Pharmacopoeia of India_, p. 52, Lond., 1868). [6] See "Appendix," vol. i. p. 419 of Sir W. C. Harris's _Highland of Aethiopia_ (2nd ed., Lond., 1844); and _Trans. Bombay Geog. Soc._ xiii. (1857), p. 136. [7] Cruttenden, _Trans. Bombay Geog. Soc._ vii. (1846), p. 121; S. B. Miles, J. Geog.

[12] "_Boswellia thurifera_," ... says Waring (_Pharm. of India_, p. 52), "has been thought to yield East Indian olibanum, but there is no reliable evidence of its so doing." [13] "Libanus igitur est mons redolentie & summe aromaticitatis. nam ibi herbe odorifere crescunt. ibi etiam arbores thurifere coalescunt quarum gummi electum olibanum a medicis nuncupatur."--_Perigrinatio_, p. 53 (1502, fol.).

One of the Chinese names for frankincense, _Ju-hiang_, "milk-perfume," is explained by the _Pen Ts'au_ (xxxiv. 45), a Chinese work, as being derived from the nipple-like form of its drops. (See E. Bretschneider, _On the Knowledge possessed by the Ancient Chinese of the Arabs_, &c., p. 19, Lond., 1871.) [16] _The Voyage of Nearchus, loc. cit._
