402. DATDRA STRAMONIDM, L. 



a. Leaves. 



b. Seed. 



Note. Ike leaves resemble those of Henbane in shape and in being 

 toothed at the margin, but are not hairy, and the stem leaves are stalked, 

 not sessile as in Henbane. For fig. of plant, see Bentley and Trimen, 

 Med. Plants, tab. 192. 



403. HYOSCYAMDS NIGER, L. 



a. Leaves. (Annual Henbane.) 



b. Ditto. (Biennial Henbane.) 



c. Seed. 



Note. The radical stalked leaves of the biennial plant are often sold 

 as Annual Henbane. In the Annual Henbane plants the small radical 

 leaves are withered before the plant blossoms, therefore all the leaves 

 in the annual drug should be without stalks. For the seed, see P. J. 

 [2] , vol. ix., p. 233. Henbane leaves may be known in the dried state 

 from Stramonium by the leaves being hairy, not smooth, and from 

 Belladonna by the leaves being toothed in the margin. For fig. of plant, 

 see Bentley and Trimen, Med. Plants, tab. 194. 



404. NICOTIANA TABACUM, L. 



a. Leaves. (Tobacco.) 



Note.Tob&ceo is yielded by several different species. N. Persica 

 yielding the Persian ; N. rustica the Latakia, Turkish, and Manilla ; N. 

 repanda the Cuban and Havana. See Bent. Man., p. 580 ; P. J. [1] , 

 vol. iii., p. 342 ; P. J. [3] , vol. ii., p. 666. For fig. of plant, see Bentlty 

 and Trimen, Med. Plants, tab. .191.

a. Section of stem, showing manner of incising the bark. 



See P. J. [3] , vol. iii., p. 422.

 /. Mannite. See P. J. [1], vol. vi., p. 183. 



Note. Manna is not now produced in Calabria as an article of com- 

 merce. P. J. [3] , vol. iii., p. 422 ; P. J. [2] , vol. xi., p. 326. Artificial 

 manna either contains no mannite at all, or not more than 40 per cent., 

 while true manna contains 70-80 per cent. Spurious manna is known 

 by its uniform colour and freedom from the slight impurities, as well as 

 from the peculiar odour and slight bitterness of manna. P. J. [1], 

 vol. iv., p. 567. Mannite occurs also in many other plants. Sea 

 Miller"! Chem., pt. iii., p. 321 ; P. J. [1] , vol. iv., p. 667 ; [1] , vol. viii., 

 pp. 480-482; [1] , vol. x., p. 124; [1], vol. xvi., p. 630; [2], vol. xi., 

 p. 629. For Artificial Mannite, see P. J. [3], vol. i., p. 864. For fig. of
