Anthemis (Compositae). 
For more than a year the investigation of this genus has been 
carried on in my laboratory at Haarlem, and I utilised my stay at 
Kew in order to extend it to some new species. In summarising 
the results hitherto obtained, it may be said that the seeds of 
the following contain much HCN : A, aetnensis, Schouw, A. 
alttssima, Li, A. arvensis, L., A. austriaca, Jacq., A. Blancheana, 
oiss., A. chia, L., A. Cota, L., A. elbuensis? A. montana, 1... 
A. rigescens, Willd. In all cases I determined the amount of 
seeds were mostly presented by the Jardin des Plantes at Paris. 
From a large quantity of seeds of A. aetnensis, and A, chia, 
obtained from the firm of Haage and Schmidt of Erfurt, I have 
prepared the cyanogenetic glucoside. It belongs to the amygdalin 
type, giving off hydrogen cyanide and benzaldehyde on hydrolysis. 
The strong odour of benzaldehyde may even be observed on 
grinding the seeds with water. imo 
uthemis contains é.a, the parent plant of “ Roman Camomile 
(A. nobilis, L.) of which the ethereal oil has frequently been 
examined. Apart from this little is known as to the activity of the 
genus, A. Cotula, L., is sometimes called in English “ Poison 
Daisy.” Compare the note under Dimorphotheca concerning hydro-
