The carvacrol used was obtained from Schuchardt and 

 boiled constantly at 236°. The same proportions of zinc- 

 ammonium-bromide and ammonium-bromide were used as in 

 the foregoing investigations and the mixture was heated for 

 the same number of hours at 350°-36o°. 



The reaction-mass consisted of a light golden-brown under- 

 layer, and a darker overlying layer of a granular consistence, 

 intermixed with a considerable quantity of a light-yellow oil. 

 The sides of the tubes were covered with drops of water. 

 Pressure almost none. 



In the corresponding experiments with carvacrol, zinc- 

 ammonium-chloride and ammonium-chloride, the pressure in 

 tubes was considerable, the escaping gas possessed an agree- 

 able aromatic odor and burned with a feeble flame. In these 

 experiments more carbonized substance was formed than 

 when the bromine compounds were employed. The products 

 were isolated by previously described methods.

a yellowish-brown oil distilled by the first distillation at 240°- 

 245°, leaving a small quantity of carbonized substance in the 

 bulb ; by the second, almost entirely between 241 "-242°. 

 The freshly distilled amine was nearly colorless, and upon 

 exposure to the air turned yellow, then brown. It solidified 

 and crystallized indistinctly at —16° C. 

 The analysis gave the following result : — 



0.1497 gr. substance gave 0.4448 gr. carbon-dioxide, and 

 0.135 1 gr. water, corresponding to 0.12 13 gr. C. and o. 1501
