Experimental.— The material received from Gladstone, 

 ( v Mi eiisl-tiid, came to Sydney by sea, and it was quite dry 

 when it reached us; 107 fbs. of leaves and terminal branch- 

 lets gave 2l£ ounces of oil, equal to l*25°/\ The material 

 from Port Macquarie was also quire- dry when distilled, and 

 2.52 lbs. of loaves and branohlet.s gave 101 ounces of oil, 

 equal to 2 , 58:/°. The close agreement of the two crude oils 

 can be seen from the following results : —

When the crude oil of both samples was dissolved in eight 

 or ten volumes acetic acid and bromine added in excess, 

 after a very short time the mixture became reddish, then 

 violet, and soon of a deep indigo blue, which colour remained 

 permanent for a long time. 



The crude oil of M. thijmi folia 1 does not appear to give 

 this colour reaction, although in general characters it closely 

 approaches the oil of this Melaleuca. The colour reaction 

 is given readily with the oil of M. uncinata, but not so 

 distinctly with that of M. linariifoliu. 



For distillation, 100 cc. of the oil of the Gladstone sample 

 were taken, about 1 cc. came over below 173° C. (corr.); the 

 thermometer then slowly rose to 176° by which time 50 cc. 

 :;i<: distilled; between 176-178° 30 cc. more came over, 

 and between 178-184° 10 cc. distilled; between 184-195°
