which have a very distinct deep groove around them, for the 

 purpose of attaching the handle. They are not numbered. 



Another photograph (Plate XV, Pig. 3), shows six magical 

 stones, all of which are different from those described, 

 excepting No. 3, which is the same stone depicted as No. 9 

 in Fig. 1. Nos. 1, 2, 3, and 4, are of the same material as 

 No. 9 in Fig. 1. Nos. 8 and 10 are clay-slate, while the rest 

 are grey sandstone. The three small articles on the floor 

 of the picture are stone hatchets used by the aborigines, 

 and are without numbers. 



ON THE AUSTRALIAN MELALEUCAS AND THEIR 



ESSENTIAL OILS, Part IV.

Melaleuca genistifolia, Sm. 



Historical.— This species was described as far back as 

 1796, by Dr. Smith, in Trans. Linn. Soc, London, III, 277. 



Bentham in his Flora Australiensis, Vol. Ill, p. 144, 

 (1843, 1858) synonymises M. lanceolata, Otto, and M. 

 bracteata, F.v.M. under it. 



In our third paper on the Melaleucas published in this 

 Journal, Vol. XLIV, it is shown both botanically and 

 chemically that M. bracteata is quite distinct from M. 

 genistifolia, and further it will be demonstrated in a later 

 paper that M. lanceolata is all that is claimed for it as a 

 species.
