595. ALOE SOCROTRINA, continued. 



c. Inspissated juice. (Mocha, or MoJca Aloes.) From 



Wright & Co. 



d. Ditto* Presented by Dr. A. Leared. 



Note. This kind of aloes has been imported from Muscat. It is of 

 inferior quality, containing usually 25 per cent, of impurity. Per. Mat. 

 Med., vol. ii., pt. i., p. 192. Hanbury attributes it to Aloe Socotrina. 

 Pharmacographia, p. 616. Its odour is intermediate between that of 

 Socotrine and Barbados aloes, which would seem rather to indicate that 

 it is produced by Aloe Indica, Eoyle, which Hanbury thinks is a slight 

 variety of Aloe vulgaris, Lam. Pharmacographia , p. 622 ; P. J. [1] , 

 vol. xii., p. 268. For fig. of plant, see Bentley and Trimen, Med. Plants, 

 tab. 283. . 



e. Socotrine aloe juice, No. 1. 



/. Socotrine aloes prepared, No. 2, from No. 1. 

 g. Large skin of false Socotrine aloes. 



Note. Specimen e is the one alluded to in Per. Mat. Med., vol. ii., 

 pt. i., p. 188. It was imported into London from Madras, but was first 

 purchased from some Arabs on the coast of the Eed Sea. 



~h. Zanzibar aloes. Presented by Mr. F. J. Hanbary. 

 Note. This kind of aloes is imported in monkey skins. It is the kind 

 mentioned in Pharmacographia, p. 622. The odour of the specimen h is 

 similar to that of Socotrine aloes bust less agreeable, and the surface is 

 duller and more resinous-looking. 



596. ALOK FEROX, Lam. 



a. Portion of the stem. Bentl. & Trim., Med. Plants, tab. 284. 

 &. Inspissated juice. (Cape Aloes.) ' 



c. Ditto. (Socotrine Cape Aloes.} Two specimens. 



d. Ditto. (Hepatic Gape Aloes.) Two specimens. 



e. Ditto. (Natal Alo.es. y 



f. Resin deposited from a decoction of aloes. 



Note. Other species, such as Aloe ferox, L., A. perfoliata, L., also yield 

 Cape aloes. A. Africana, Mill, and A. plicatilis, Mill, are said by Dr. Pappe 

 to yield a less powerful kind. Specimens c and d are the' specimens /3 

 and y mentioned by Pereira in his Mat. Med., vol. ii., pt. i., p. 192. 

 They were sent to him by Mr. Dunsterville of Algoa Bay. Natal aloes is 

 produced by a large aloe which has not yet been identified, but from the 

 similarity of the odour of the drug to Cape aloes, it is here classed with it. 

 It closelyresembles hepatic aloes in appearance, but has an odour like Cape 

 aloes, and usually presents a powdery surface. Hepatic aloeshas an odour 

 like Socotrine aloes, and a dull and opaque, not a powdery, surface. 

 Socotrine aloes may be recognised by its reddish tint, and by the frag- 

 ments being nearly transparent, as well as by its odour. 



597. ALOE VULGARIS, Lam. 



a Stem. See Bentley and Trimen, Med. Plants, No. 282. 



b. Leaves, preserved wet. 



c. Inspissated juice. (Barbados Aloes.) Two specimens.
