of the electrical conductivitj ot" carvacrol 

 or tliymol are known to the aulhors, but probably no appre- 

 ciable dissociation takes place, since tlie toxic action seems to be 

 unclianged by the addition of Na OH, indic.ating the absence of 

 H ions. The entire molecule in both ot these substances is, there- 

 fore, to be regarded as responsible for the poisonous effect here 

 Seen. 



The introduction of the isopropyl group (CH [CHs]2) is here 

 Seen to very materially increase the toxic properties of the mole-
