oil forwarded is certainly a near approach to the fine Olive oil of Europe. 
Price varying from Rs. 2-8 to Rs. 5-12 per maund. 
* Another letter has just been received from Mr. Crozier, intimating the 
despatch of some more contributions for the Exhibition, and of some 
medicinal plants, minerals, gums, etc. The process of preparing Wound 
oil is also described, and will be noticed hereafter as soon as the plants 
employed in the process are identified by the Professor of Botany. The 
demand for the oils of India is steadily on the increase, and it is de- 
sirable that every means should be used to give publicity to the subject, 
as there are several manufactures in which the solid fatty oils of India 
might be advantageously substituted for Tallow, Wax, or Spermaceti; 
some of the fine oils of this Presidency might also be brought more ex- 
tensively into use if more were known about their quality, colour, smell, 
and price. Experiments are being tried with some of the Indian oils, 
and any information or specimens will be thankfully received and ac- 
knowledged." 
On the Botany of the NORTH-WESTERN District of WESTERN 
AUSTRALIA. 
[At p. 188 of our last volume we announced the safe return to Swan 
River of the venerable James Drummond, from a long and interesting 
tour of eighteen months’ duration, to the northward of that river. We 
have now the pleasure of giving some account of the botanical success 
of that tour. Of the plants themselves we cannot speak till their 
arrival, which is almost daily expected.—Eb.] 
The Swan River district and the country south between the Swan and 
King George’s Sound, Cape Riche, and as far to the east as Middle 
Mount Barren, have been partially examined, many new plants found, 
` and an account of them published in various botanical publications, but - 
as yet little is known of the botany of this colony to the north of the 
Moore River. 
Having lately travelled from the Moore River to the Murchison 
(latitude 274° south), and taken several excursions to the east and 
west of Dundaragan, I send you some account of the plants I met 
with, premising that I shall principally confine my observations to
