Tn most cases Mr. Brewer informs us directly, or in some way indi- 
cates, which are the aliens of the Surrey flora; but, occasionally, further 
observation or greater carefulness in expressing the results of observa- 
tion as regards the citizenship of species, would have improved the . 
book. For instance, for anything that appears in the Flora, Hesperis 
matronalis may be a plant of hilly Surrey pastures, in the same sense 
as the Bee-Orchis, or Anacharis as much an inhabitant of the Surrey 
‘Streams as Ranunculus aquatilis. Mr. Watson’s notices of stations are 
very full of detail, and being so are, as might be expected, often 
valuably suggestive of points regarding the geography of species, over 
and above the mere fact that a given plant grows in such and sucha 
. Place, An interesting part of the book is a copious list of the intro- 
duced plants of Mr. Irvine’s English ‘ Port Juvenal,’ the Thames side 
at Wandsworth and Battersea; and it is explained that in this case the 
Species have originated, not with foreign wool,. but from the refuse of 
foreign corn from the Wanslsworth water-side distillery. For a county 
‘Where the hills ascend to nearly 1000 feet, we should have been glad 
to hear something of the elevation which some of the species attain. 
— There is an elaborate table, at the conclusion of the work, of the geolo- 
. gical range of the species, the plants ascertained to grow upon each of 
‘the eleven formations being separately indicated. We have studied the 
book with much interest, and have great pleasure in recommending it 
to the favourable attention of our readers.

_ Few botanists have done so much towards making us better ac- 
a i with the vegetation of Australia than Dr. Mueller, the inde- 
— fitigable director of the Botanic Gardens at Melbourne. Nearly 
_ tty month he issues a fascicle of his ‘ Fragmenta,’ containing all the 
. RW discoveries which his own explorations, those of the Australian 
. “tpeditions, and the labours.of Messrs. Moore, Hill, Maxwell, Beckler, 
and ot ers, are constantly accumulating, What a gain for science if 
Aall great Herbaria the practice obtained of examining every newly- 
Wrved collection, and carefully describing the new genera and species,
