512. LIQUIDAMBAR ORiENTALis, continued. 



j. Storax in mass. (Drum Storax.) 



Note. This specimen is alluded to by Pereira tinder the head of red- 

 dish brown storax. Prof. Guibourt considered it to be " falsified brown 

 storax." It is covered with minute white crystals which are flat, unlike 

 the acicular crystals of styraciu, usually found on sty nix calamita. 



513. LlQUIUAMBAR STYRACIFLUA, L. 



a. Balsam. (Liquidambar, Sweet Gum, Copalm Balsam.) 



b. Cylindrical earthenware jar containing balsam of 



liquidambar, from Guatemala. Presented by Mr. D. 



Hanbury. 



Note. Liquidambar is produced in the Southern States of America. 

 Its odour is more terebinthinous than that of liquid storax, which it 

 otherwise much resembles. It has been used in the form of ointment 

 for healing indolent ulcers and for cutaneous diseases. See Amer. 

 Dispens., p. 489. Liquidambar .Altingia, Bl., yields a similar product in 

 Tenasserim. P. J. [1] , vol. viii., p. 243. A syrup of liquidambar is 

 used in America for the diarrhoaa of infants. It is made by the same 

 formula as that given in the U. S. Pharmacopoeia for syrup of Prunus 

 Virginiana. See P. J. [1] , vol. xvi., p. 336. 



c. Liquidambar mou, ou blanc. Presented by Prof. 



Guibonrt. 



Note. This is the specimen mentioned by Pereira in his Mat. Med., 

 vol. ii., pt. i., p. 336, as being distinct from commercial liquidambar. It 

 resembles Chian turpentine in appearance, and styrax in odour. See 

 Hist, des Drag. , vol. ii., p. 306. 



f c. Section of the trunk from Guatemala. Presented by 

 Mr. D. Hanbury. 



SALICACE^}. 



514. POPULUS BALSAMIFERA, L. (Tacamahac Poplar.) 



a. Leaf buds. 



Note. The leaf buds of this species, and of P. nigra, L., are used to 

 make an ointment, and to prevent rancidity in other ointments, in which 

 property they are said not to be equal to paraffin. See Lind. Fl. Med., 

 p. 320. Amer. Dispens, p. 664. For formula see Cooley's Cyclopaedia, p. 855. 



515. POPDLUS TREMULOIDES, Mich. (American Aspen, American 



Poplar.) 



a. Bark. (White Poplar Baric.) 



Note. This bark is used as a bitter tonic and febrifuge in America. 

 Amer. Dispens., p. 666. It somewhat resembles slippery elm bark in 

 appearance, but the latter has an odour like fenugreek, and is not bitter 

 like poplar bark. See Amer. Dispens., p. 665. 



516. SALIX CAPREA, L. (Great Sallow, Bound-leaved Willow.') 



a. Bark. (Willow Bark.) 



Note. Several other species yield willow bark. The bark of Salix 

 purpurea, L., is stated to be intensely bitter. S. Caprea is known by its 

 broad flat ovate leaves, with wavy margins. The bark has been used in 

 agues. See Per. Mat. Med., vol. ii., pt. i., p. 337.
