of green, to remove which it is exposed to sunlight ; it thus acquhes a

The investigations of several chemists, performed in 1878-79 in 



Fittig's laboratory, have shown the oil to contain the following con- 

 stituents : — At 147-14)8° C. isohutylic ethers and hydrocarbons arc 

 distilling, at 177° angelicate of isohutyl, at 200^-201° angelicate of 

 isamyl, at 204''-205° tiglinate of isamyl (both these compound ethei-s 

 answering to the formula C'H'O.OC'H"). In the residual portion 

 hexylic alcohol, C'ff'OH, and an alcohol of the formula C'"ff«0, are met 

 with, both probably occurring in the form of compound ethers. By de- 

 composing the angelicates and the tiglinate above named with potash, 

 angelic acid, C^H^O^ and tiglinic (or methylcrotonic) acid, isomeric to the 

 former, are obtained to the extent of about 80 or more per cent, of the 

 crude oil. In the oil examined by Fittig, angelic acid was prevailing ; 

 from another specimen E. Schmidt (1879) obtained but very little 

 of it, tiglinic acid was by far prevailing (see also article Oleum 

 Crotonis). 



We have performed some experiments in order to isolate the hittn' 

 principle, but have not succeeded in obtaining it in a satisfactory state 

 of purity ; it forms a brown extract, apparently a glucoside. We can 

 also confirm the statement that no alkaloid is present. 



Uses— An infusion or an extract of chamomile is often used as a 

 bitter stomachic and tonic. 



Adulteration and Substitution— The flower-heads of Mo.tr'mm 

 Chamomilla L., designated in Germany Common Chamomiles {gemeine 

 Kamillen), are sometimes asked for in this country. In aspect as weU 

 as in odour, they are very different from the chamomiles of Engbsli 

 pharmacy ; they are quite single, not bitter, and have the receptacle 

 devoid of scales and hollow. 



A cultivated variety of Chrysanthemum Parthenium Pers., or 

 Feverfew, with the florets all ligulate, and some scales on the receptacle 

 (not having the receptacle naked, as in the wild form), common lo 

 gardens,' has flower-heads exceedingly like double chamomiles, nm 

 they may be distinguished from the latter by their convex or i 

 flat receptacle, with the scales lanceolate and acute, and less membran- 



nearhj 



ous. 



The chamomiles of the Indian bazaars which are brought froni 

 Persia and known as Bdbunah, are (as we infer from the statement <^ 

 Royle) the flowers of Matricaria suaveolens L., a slender form^ ot «^ 



the 



Chamomilla, growing in Southern Kussia, Persia,' Southern Siberia 

 in North America. 



The fresh wild plant of Anther.iis nobilis L., pulled up from 

 ground, IS sold in London for making extract, a proceeding higiny 

 prchensible supposing the extract to be sold for medicinal use.
