189. RARER ALKALOIDS. 203 



Conessine or wrigMne, see Haines 1 and Stenhouse. 2 It is very 

 sparingly soluble in alcohol, ether, and bisulphide of carbon. 



Harmaline and harmine, compare Fritsche. 3 The former yields 

 yellow salts with acids the latter colourless. Both are some- 

 what sparingly soluble in alcohol. 



Surinamine is also sparingly soluble in spirit. (Compare Hiitten- 

 schmidt and Winkler. 4 ) 



Aribine, see Rieth. 5 It is sparingly soluble in ether, as is also 



Atherospermine, compare Zeyer ; and Rhceadine, compare Hesse. 7 

 The latter is colourless, but is converted by dilute acids into 

 deep red rhoeagenine. 



Fioline, compare Boullay; 8 for beberine, see Maclagan 9 (cf. 171); 

 for belladonnine, see Hiibschman j 10 for cocaine and hygrine, compare 

 Niemann, Wohler, and Lessen. 11 Concentrated hydrochloric acid 

 decomposes cocaine into benzoic acid, and the alkaloidal ecgonine. 



For chlorogenine and porphyrine see Hesse. 12 Chlorogenine in 

 acid solution shows a powerful blue fluorescence. 



Corydaline, compare Wackenroder, Miiller and Leube, Boedecker 

 and Wicke. 13 The alkaloid dissolves in cone, sulphuric acid, with 

 dark red colouration. 



Cytisine, compare Husemann and Marme. 14

 Alstonia constricta is probably a mixture of these two alkaloids (Hesse).
