acknowledged. Nor will the advantage herein be all on the side 

 of the Author. For, if collectors who send him specimens will 

 carefully number them, and keep a duplicate set numbered 

 to correspond with that forwarded, he will undertake to send 

 in return names, according to the list of numbers. In this way 

 the student may easily have his whole collection correctly named, 

 provided he make no mistake in putting two different plants 

 under one number. 



Collections of specimens intended for the Author may be 

 sent to Charles Moore, Esq., Botanic Gardens, Sydney ; to 

 Dr. Ferdinand Mueller, Botanic Gardens, Melbourne ; or 

 to George Clifton, Esq., Fremantle, Western Australia. 

 Or, if sent to England, they may be addressed to Sir W. J. 

 Hooker, Royal Gardens, Kew ; or to the publisher, Mr. Lovell 

 Reeve, 5, Henrietta Street, Covent Garden, London.
