Part Used and Name. CINNAMODENDRON, Spurious Winter's 

 Bark; the bark. It is not official in the British Pharmacopoeia, 

 the Pharmacopoeia of India, or the Pharmacopoeia of the United 

 States. The true Winter's Bark, obtained from Drimys Winteri, 

 Forster, was official in the United States Pharmacopoeia of 1850, 

 and also in the Dublin Pharmacopoeia of 1826. 



General Characters and Composition. This bark has been 

 already referred to under the head of Canella alba, as the one 

 long known and used in England and elsewhere for the true 

 Winter's Bark, and therefore, as being probably the bark commonly 

 referred to by writers, for which Canella Alba bark was for- 

 merly said to be substituted ; hence it has been termed 

 Spurious Winter's Bark. It is found in quills, which are com- 

 monly ten, twelve, or more inches in length, and one or two 

 inches in diameter. It is covered by a thin corky outer coat, 

 which has a dull reddish-grey or ferruginous-brown colour, and is 

 marked with rounded depressions or scars. Internally it is 

 yellowish-brown, reddish-brown, or of a deep chocolate colour. 

 Its fracture is short and granular, but somewhat fibrous inter- 

 nally. It has an agreeable aromatic odour resembling cinnamon, 

 and a very pungent taste, without any bitterness. Cinnamo- 

 dendron bark may be readily distinguished from true Winter's 

 Bark for which, as just noticed, it has been commonly substituted, 

 both by its structural and chemical characteristics. Thus the 

 latter is marked on its inner surface by very rough striae, caused 

 by the great contraction of the inner layer in drying, while the 

 inner surface of the former is nearly smooth ; and while a decoc- 

 tion of true Winter's Bark is not sensibly altered in colour by 

 iodine, that of Cinnamodendron Bark is changed to a deep pur- 

 plish-brown under the same circumstances. 



Cinnamodendron bark may be also readily distinguished from 

 Canella Alba bark, by the darker colour of its inner surface ; and
