displacement of the acetyl group. Bikhaconitine like other aconitines 

 produces in excessively dilute Solution a tingling Sensation on the 

 tongue. The toxicity tovvards warm blooded animals is greater than 

 that of aconitine and japaconitine owing to its greater depressing 

 action on the respiratory function. 



During the course of investigation on the aconitines two groups 

 of alkaloids have been determined. (a) the aconitine group including 

 aconitine from Aconitum Napellus, japaconitine from A . japo- 

 iiicum or A. Fischeri, pseudaconitine from A. dimorrhizmny 

 bikhaconitine from A. spicatum, indaconitine from A. chas- 

 mantlium. All these are highly poisonous. iß) The atisine group 

 including atisine from A. heterophyllum and paimatisine from 

 A. palmatum. These are not poisonous in the ordinary sense.

Easterfield, T. H. and G. Bagley, The Resin Acids of the Coni- 

 ferae. Part I. The Constitution of Abietic Acid. (Journ. 

 Chem. Soc. London. Vol. LXXXV. 1904. p. 1238—1249.) 



The following probable constitutions are given: 



Rimnic acid, CitiHjoO. = oxymethylphenanthrenecarboxylic 



acid. 

 Podocarpic acid, Cit H-.. Oa = oxydimethylphenanthrene- 



carboxylic acid. 

 Abietic acid, C19 M..8 O-.- = methylisopropylphenanthrene- 



carboxylic acid. 

 Pimaric acid, C20H30OJ = dimethylisopropylphenanthrene- 

 carboxylic acid. 

 The observations of the authors dont lend support to the view 

 that abietic acid is an oxidation product of the terpenes. They 

 suggest that terpenes act as solvents in which the resins are renio- 

 ved from the plant system and that this is the true meaning of the 

 constant association of the two classes of Compound.
