circumstance that had attended their collection, at a distance of more 
than half a century back from the time I speak of. He it was who 
first possessed me with a desire to explore the American shores, a de- 
sire which has followed me through life, though as yet it has been but 
very imperfectly gratified. With this small tribute to his memory I 
may appropriately close this general expression of my thanks to those 
who have aided me in the present undertaking.” The rest of the pages 
are devoted to the botanical history of the genera and species. 
The author's admirable ‘ Phycologia Britannica,’ in three volumes, 
royal 8vo, each volume containing 120 plates, with full synopses and in- 
dexes, is completed ; but, valuable as the contribution to our knowledge 
of the Alge the ‘Nereis Boreali-Americana’ is, we trust that the con- 
tinuation and completion of the ‘Nereis Australis a work of equal 
value with the present, will not thereby be delayed, and of which we

We are happy to find this important work continued with unabated 
zeal and talent. It has extended now to three volumes complete, each 
with 100 plates, and we have now before us three numbers with thirty- 
nine plates of vol.iv. Vol. ii. is rich in Polygonee, Composite, and 
Geniste among Leguminosae ;—Vol.iii., scarcely less so in Composite, < 
including some very remarkable genera and species; and several new 
species of Amygdalus, of Ebenus, Haplophyllum, Nitraria, Reaumuria, 
etc., are admirably illustrated. The three numbers of the third volume 
have many plates devoted to Grasses, others to new Thymelaceous 
plants. In no work that we are acquainted with, is more labour be- 
stowed on careful diagnosis and admirable analysis of figures. +
